Dark Energy and the Runaway Universe, Dr. Alex Filippenko, UC Berkeley
Are the slight quantum fluctuations of energy levels of electrons in an atom evidence of dark-energy-radiation?
Observations of very distant exploding stars show that the expansion of the Universe is now speeding up, rather than slowing down due to gravity as expected. Over the largest distances, our Universe seems to be dominated by a mysterious, repulsive dark energy that stretches the very fabric of space itself faster and faster with time.

Black Holes, Exploding Stars, and the Runaway Universe: A Life in Science
January 23, 2019
Dr. Alex Filippenko (University of California, Berkeley) reviews his fascinating research career in astronomy, focusing on his work with black holes and with active galaxies and supernovae (exploding stars) -- and their role in helping us determine the ultimate fate of the universe. He also talks about some of the circumstances and people that influenced his work as a scientist, about the importance of education and outreach for the public support of science, and about his work to help ensure the future of Lick Observatory, the first permanently occupied mountain-top observatory in the world.
Dark Energy and the Runaway Universe | Alex Filippenko | Talks at Google
We expected the attractive force of gravity to slow down the rate at which the Universe is expanding. But observations of very distant exploding stars (supernovae) show that the expansion rate is actually speeding up, a remarkable discovery that was honored with the 2011 Nobel Prize in Physics to the teams' leaders. Over the largest distances, the Universe seems to be dominated by a repulsive dark energy -- an idea Albert Einstein had suggested in 1917 but renounced in 1929 as his biggest blunder. It stretches space itself faster and faster with time. But the physical origin and nature of dark energy, which makes up about 70% of the contents of the Universe, is probably the most important unsolved problem in all of physics; it may provide clues to a unified quantum theory of gravity.

Purpose and the Universe : Sean M. Carroll
For HD slides -
Here’s another talk by Sean Carroll back in 2013. In this presentation, Sean Carroll discuses how universe works and how it is related to philosophy. In particular, he discusses of whether is possible to find a purpose of existence by studying the principles of physics. Along the day, Carroll briefly discusses the views of the philosophers and scientists from the past. Finally, the talk is concluded by arguing that purposes can be created even if they do not come from fundamental physics.

Sackler Astronomy Lecture: The Search for Planet Nine
Recent evidence suggests that a massive body is lurking at the outskirts of our solar system, far beyond the orbits of the known giant planets. This object, at a distance approximately 20 times further than Neptune and with a mass approximately 5000 times larger than Pluto, is the real ninth planet of the solar system. In his lecture, Mike Brown talks about the observation that led his team to the evidence for this Planet Nine and discusses how so massive an object could have been hiding in the outer solar system for so long. He also discusses the international effort to pinpoint this newest member of our planetary family.
Mike Brown is the Richard and Barbara Rosenberg Professor of Planetary Astronomy at the California Institute of Technology, specializing in the discovery and study of bodies at the edge of the solar system. He is best known for his discovery of Eris, the most massive object found in the solar system in 150 years, which led to the debate and eventual demotion of Pluto from a real planet to a dwarf planet. In 2006 he was named one of Time Magazine's 100 Most Influential People and was inducted into the National Academy of Sciences in 2014.

Lawrence Krauss CERN Cosmology Lecture - Inflation to Eternity
Lecture given by Professor Lawrence M. Krauss at the CERN Colloquium on Cosmological Physics.
The last decade or two have represented the golden age of observational cosmology, producing a revolution in our picture of the Universe on its largest scales, and perhaps also its smallest ones. In this lecture, Prof. Krauss will argue that these recent development bring to the forefront some vexing questions about whether various fundamental assumptions about the universe are in fact falsifiable. In this he will focus on 3 issues: (1) Proving Inflation, (2) Dark Energy and Anthropic Arguments, and (3) Cosmology of the far future.
In 2014, the potential smoking gun for inflation was thought to have been found with the following experimental techniques Super-sensitive, superconducting microwave detectors, built at NIST, and implemented at BICEP and Keck telescope arrays at the South Pole have allowed astrophysicists to find out some of the answers with new observational results.
The Background Imaging of Cosmic Extragalactic Polarization (BICEP) results are indirect evidence for the existence of the elusive gravitational waves from the big bang itself.
By using highly sensitive microwave detectors, developed at the National Institute of Standards and Technology (NIST), telescope cameras can detect the polarization direction of photons emitted from the moment of last scattering between the photons and electrons in the plasma of the early universe, before stars and galaxies could form.
These photons make up the CMB Radiation, which radiated outward after electromagnetic radiation decoupled itself from the plasma state of matter in the early universe, as the plasma formed into a gas, making space transparent for the first time. The photons emitted at the moment of last scattering, 13.7 Billion years ago, were gamma ray photons. Since then, they have been travelling almost uniformly, in every direction across the universe. Since the universe is expanding, these photons have stretched with the fabric of spacetime as the universe expanded and this has stretched their wavelength from gamma rays to microwaves.
The apparently uniform pattern of polarization in the CMB can be broken into two components.
One, a curl-free, gradient-only component, the E-mode (named in analogy to electrostatic fields).
The second component is divergence-free, curl only, and is known as the B-mode (named in analogy to magnetic fields).
Cosmologists predict two types of B-modes, the first generated during cosmic inflation shortly after the big bang, and the second generated by gravitational lensing at later times.
Now, the BICEP team has confirmed detection of the first type of B-modes, consistent with inflation and gravitational waves in the early universe
However, there are now grave doubts over the validity of the results. The BICEP2 team underestimated how much dust in our own galaxy can polarize microwave radiation, which was tested with ESA's Planck Mission that observed these effects and compensated for them. In order to salvage any hope of a discovery claim they will have to take more data from BICEP2 and Planck, compensate for the effects of space dust, and then publish the paper before making any announcement as it is a big claim to make, to be sure whether they had in fact seen the first signs of gravitational waves from the Big Bang, or were fooled by the effects of intergalactic space dust. Either way the results were announced too early and without proper scrutiny. The results may yet be salvaged when the results are compensated for the intergalactic dust or they may have to go back to the drawing board and wait for a new series of experiments, including an orbiting satellite for observing B-mode polarization from the CMB. Either way, we are making progress as we now have a real opportunity to answer observational questions that would not have even been asked a decade ago.

In an event integrated in the 4th European Conference for Science Journalists, Lawrence Krauss, the acclaimed author of A Universe from Nothing, will be telling the greatest story ever told about the universe. An evening mixed with some of the finest cocktail mixology, light installations, live art by Henrik Schutze and music performances by Tromleorkestret feat. ROSYAN on cello and their robotic, fire spitting barrel organ, as well as the funky, steamy and surf jazz by the superstars The Orgelheimers and, last but not least, a piece that will trigger specific electrical impulses in your brain with incredible 2D graphics and algorithmic electronic music by Vectral.
We may have unexpected connections to life elsewhere in the solar system, and you are also directly connected to almost every being that has ever lived on Earth. And even the most esoteric developments at the forefront of physics, from the Large Hadron Collider, to the discovery of gravitational waves impact on you in ways you might never have anticipated. In this evening, Lawrence Krauss will roam over modern discoveries in science from astronomy to particle physics, and from the remotest corners of the Universe to our own backyard.
Probing the Dark Universe - A Lecture by Dr. Josh Frieman
In this one-hour public lecture Josh Frieman, director of the Dark Energy Survey, presents an overview of our current knowledge of the universe and describe new experiments and observatories. Over the last two decades cosmologists have made remarkable discoveries: Only 4 percent of our universe is made of ordinary matter - atoms, molecules, etc. The other 96 percent is dark, in forms unlike anything with which we are familiar. About 25 percent is dark matter, which holds galaxies and larger-scale structures together and may be a new elementary particle. And 70 percent is thought to be dark energy, an even more mysterious entity which speeds up the expansion of the universe. Josh Frieman is senior staff scientist at the Fermilab and Professor of Astronomy and Astrophysics and member of the Kavli Institute for Cosmological Physics at the University of Chicago. The Dark Energy Survey is a collaboration of 300 scientists from 25 institutions on 3 continents, which built and uses a powerful 570-Megapixel camera on a telescope in Chile to carry out a 5-year survey of 300 million galaxies and thousands of supernovae to probe dark energy and the origin of cosmic acceleration.

Physics | Antimatter and Dark Matter
Dark matter is a theorized form of matter that is thought to account for approximately 80% of the matter in the universe, and about a quarter of its total energy density. The majority of dark matter is thought to be non-baryonic in nature, possibly being composed of some as-yet undiscovered subatomic particles. Dark matter has not been directly observed, but its presence is implied in a variety of astrophysical observations, including gravitational effects that cannot be explained unless more matter is present than can be seen. For this reason, most experts think dark matter to be ubiquitous in the universe and to have had a strong influence on its structure and evolution. The name dark matter refers to the fact that it does not appear to interact with observable electromagnetic radiation, such as light, and is thus invisible (or 'dark') to the entire electromagnetic spectrum, making it extremely difficult to detect using usual astronomical equipment.

Marcus Allen: Ancient Technology of the Egyptians FULL LECTURE
Join Megalithomania in November 2021 to explore this pyramid and others on a specially designed 13 day tour. Details at In modern times, granite is easily cut and shaped using diamond drills and tungsten-tipped chisels. In Ancient Egypt, 100 ton obelisks and blocks of granite were cut from the bed-rock, and shaped using diorite pounding balls, copper tools and sand. This is the accepted consensus. But these crude methods are so unlikely to have produced the visible results as to be, at best, simply a guess. The elegant and sophisticated artifacts seen across Egypt from Giza to Luxor to Aswan and displayed in the great museums of the world, are testament to whatever technique was used in their creation.
Today, this technology is a mystery to us. Stylised human/animal statues carved from granite, intricate hieroglyphs cut into granite obelisks and perfectly flat blocks of granite are some of the proof for this technology. The rain forests of South America might be the place to start looking for answers. In his illustrated presentation, Marcus will show evidence indicating the skills seemingly in use over 4,000 years ago. These results would be virtually impossible to replicate today, using the tools we are told were available in Ancient Egypt. But is the evidence for the actual technology simply ‘hidden in plain sight’?
After a career with a major Motor manufacturer, Marcus changed jobs completely and became the UK publisher of NEXUS Magazine, which he and his wife first introduced to this country in 1994. Since then, he has appeared on many TV and radio programmes and given numerous presentations both here and abroad, discussing subjects sometimes considered controversial. These include the Apollo Moon Landings, political conspiracies, and UFOs, as well as promoting NEXUS Magazine.

2018 Reines Lecture: Exploring the Universe with Gravitational Waves by Kip Thorne
The 2018 Reines Lecture was presented by Kip Thorne, winner of the 2017 Nobel Prize in Physics for the detection of gravitational waves. The discovery, part of the LIGO experiment, validated Albert Einstein’s longstanding prediction that during cataclysmic events the fabric of spacetime can be stretched, sending gravitational tremors across the universe. Thorne is a graduate of Caltech and Princeton University. His research has focused on Einstein’s general theory of relativity and on astrophysics, and he is co-founder of the LIGO Project. Among his many distinctions, Thorne has been awarded the Albert Einstein Medal, the UNESCO Niels Bohr Gold Medal, the Common Wealth Award for Science, and was named California Scientists of the Year. He was elected to the American Academy of Arts and Sciences, the National Academy of Sciences, and the Russian Academy of Sciences. In addition to his renowned scientific research in theoretical physics, he is involved in writing and movie production. Most notably, he worked on Christopher Nolan’s film Interstellar.
Exploring the Universe with Gravitational Waves: From the Big Bang to Black Holes
There are two types of waves that can propagate across the universe: electromagnetic waves and gravitational waves. Galileo initiated electromagnetic astronomy 400 years ago by pointing a telescope at the sky and discovering the moons of Jupiter. LIGO recently initiated gravitational astronomy by observing gravitational waves from colliding black holes. Thorne will describe this discovery, the 50 year effort that led to it, and the rich explorations that lie ahead.

The Search for Dark Matter - Professor Carolin Crawford
An introduction to the hunt for dark matter that takes us up to the most current research and theories:
Unlike the stars and galaxies, dark matter does not give off any radiation – we can only detect it through its gravitational pull. It accounts for a quarter of the Universe, yet we do not yet understand what it is made of. The search for a better understanding of dark matter is carried out both out in space and deep underground, and where astrophysics meets particle physics.

The Accelerating Universe - Professor Joseph Silk
The universe was static, that was the credo of all scientists and philosophers until three decades into the twentieth century, when the expansion was discovered.
Three quarters of a century later, the notion of a simple expansion of the universe was found to be wrong: the universe is accelerating. One implication is that before 2000, we believed that our successors, billions of years hence would see an ever larger space of galaxies, more numerous than grains of sand on a vast beach. Today with our telescopes we can see billions of galaxies: in the far future there would be, we once believed, uncountable billions to study and even search for signs of life. But with the discovery of accelerating space, our horizon has shrunk immensely. The distant galaxies are racing away from us at ever faster velocities. In a hundred and fifty billion years time, our Milky Way will be the only galaxy left in the observable universe. This lecture will explore the origin of this paradigm shift in our cosmic horizon, and discuss the origin of the acceleration as a phenomenon that we call dark energy.

Unraveling the mysteries of dark matter with streams of stars - public lecture by Khyati Malhan
Much like our home planet, our home Galaxy - Milky Way - also hosts several rivers. But these rivers are made of stars, and are known as “streams of stars”. Stellar streams are pristine structures that have been continuously orbiting our Galaxy for billions of years. Recently, they have sparked tremendous amount of interest among the community because of the potential scientific merits they hold for various cosmic studies. The attempt of this lecture is to demonstrate how astrophysicists (like myself) turn such star structures into a tool to probe various cosmic problems, in particular to understand the nature of dark matter.

To Infinity and Beyond: The Accelerating Universe
Dark energy is cosmology's biggest mystery—an anti-gravitational force that confounds the conventional laws of physics. It makes up more than two-thirds of the cosmos, but science is still grappling to explain what dark energy actually is. In this program, top physicists search for clues to this mystery in both the earliest moments of the universe and far into the future of the cosmos.
This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.

Colloquium, April 28th, 2016 -- Probing the Accelerating Universe with the Dark Energy Survey
Probing the Accelerating Universe with the Dark Energy Survey
The Nobel Prize in Physics for 2011 was awarded for the discovery that the expansion of the Universe is accelerating. Yet the physical origin of cosmic acceleration remains a mystery. The Dark Energy Survey (DES) aims to address the questions: why is the expansion speeding up? Is cosmic acceleration due to dark energy or does it require a modification of General Relativity? If dark energy, is it the energy density of the vacuum (Einstein's cosmological constant) or something else? DES is addressing these questions by measuring the history of cosmic expansion and of the growth of structure through four complementary techniques: galaxy clusters, the large-scale galaxy distribution, weak gravitational lensing, and supernovae. The DES collaboration built a new, 570-megapixel, digital camera for the Blanco 4-meter telescope at Cerro Tololo Inter-American Observatory in Chile to carry out a deep, wide-area sky survey of 300 million galaxies and a time-domain survey that will discover several thousand supernovae. I will overview the DES project, which achieved `first light' in September 2012 and which recently completed its third of five survey seasons, and will describe a number of early science results from the solar system to the most distant objects in the Universe.
Mapping the Heavens to Understand Dark Matter and Black Holes
From time immemorial humans have been charting the night sky to make sense of the cosmos—from the mapping of stars for navigation to today’s digital surveys of galaxies to understand dark matter. In this 60-minute-long presentation Dr. Priya Natarajan, author of the book “Mapping the Heavens,” recounts the evolution of celestial map-making and shows how maps literally track our ever evolving cosmic view. In particular, she discusses recent developments in our understanding of two invisible entities: dark matter and black holes. Dr. Natarajan is a theoretical astrophysicist at Yale University, interested in cosmology, gravitational lensing and black hole physics. Her research focuses on making dark matter maps of clusters of galaxies, the largest known repositories of dark matter.

Cosmology - The Next Decade

DATE : 03 January 2019 to 25 January 2019
VENUE : Ramanujan Lecture Hall, ICTS Bangalore
The great observational progress in cosmology has revealed some very intriguing puzzles, the most important of which are the existence of new mysterious components of the Universe: the dark matter and the dark energy. While a standard model of cosmology — the Lambda cold dark matter (LCDM) paradigm — has emerged, many puzzles are as yet unsolved. Is dark energy really just a cosmological constant (Lambda), or is it something dynamical, perhaps even a clue that Einstein’s general relativity needs modifications at cosmological scales? Is dark matter a new particle beyond the Standard Model, and do its microscopic properties leave any imprint at cosmological or galactic scales (e.g., deep inside galaxy clusters, or in dwarf galaxies)? The nature of dark matter would also have very interesting consequences for the reionization history of the Universe, which is already being constrained by observations of high redshift quasars and galaxies and is expected to be determined in considerable detail by upcoming and future 21cm experiments.
This is therefore a very exciting time in cosmology as we make new proposals for cosmological experiments and wait for the next generation of the already approved experiments to become operational. The nature of data that will be provided by the next generation of cosmological experiments would be overwhelming quantitatively (in the case of large scale structure surveys) and very different from the current data sets qualitatively (in the case of the CMB spectral distortions and polarization and 21 cm experiments). There are also large gaps — mainly driven by astrophysical uncertainties in our theoretical understanding of the large scale structure; these must be filled in order to get the full benefit of these new data sets.
This is the backdrop against which we plan to have the School and Workshop to explore and discuss these issues as we look forward to another 10 exciting years in cosmology.
The topics covered in the School will include:
1. Cosmological perturbation theory and CMB anisotropies
2. Growth of cosmological LSS and the Cosmic Web
3. Gravitational lensing
4. 21cm physics
5. Galaxy formation and evolution
6. Galaxy clusters
7. CMB spectral distortions
8. Large-scale relativistic effects in the observed LSS
9. Astro-particle physics, dark matter detection and neutrino cosmology
10.Cross-correlations between observational probes
12.Gravitational wave physics and cosmology
The Workshop will bring together a larger number of scientists working in these and related areas for a more advanced discussion of the latest developments in these and related areas.
In addition, as part of the workshop, there will be one day (a Survey Day) reserved for detailed discussion current and upcoming large scale structure and CMB experiments, especially keeping mind core Indian involvement to specific missions and surveys.
As part of the program there will be Infosys - ICTS Chandrasekhar Lectures by Prof. Rashid Sunyaev, ICTS Distinguished lectures by Prof. Richard Bond and ICTS Vishveshwara lecture by Prof. Lyman Page.

Einstein, Black Holes and Cosmic Chirps - A Lecture by Barry Barish
Albert Einstein’s theory of general relativity, developed 100 years ago, predicts the existence of gravitational waves. In February 2016, the Laser Interferometer Gravitational-wave Observatory (LIGO) became the first experiment to observe gravitational waves, created by two black holes spiraling into each other. The discovery became known as the chirp heard around the world. Four month later, a few hours before this public lecture, LIGO announced the discovery of a second signal. This lecture, given by Dr. Barry Barish, LIGO director from 1997 to 2006, explains the physics of gravitational waves, the detection technique used by LIGO, the observations made and the implications these discoveries have on our understanding of the cosmos.

Jesse Thaler, MIT, Confronting the Invisible Universe
Dark matter is an enigma. Even though it can be seen through its influence on gravity, dark matter is invisible to the other known forces of nature. There are numerous ongoing efforts to discover the origin and properties of dark matter, ranging from laboratory experiments to astrophysical investigations. This intense interest is driven in part by tantalizing hints that the nature of dark matter might be linked to other deep and unsolved mysteries in physics. In this talk, Professor Thaler presents the overwhelming evidence for dark matter as well as speculates on the broader implications of the invisible universe.

Defining, Describing, and Detecting Life in the Universe - Cecilia Sanders - 7/10/20
The discovery of life elsewhere in the Universe could be the most important scientific discovery in history. Is there life out there? How do we define it? How can we detect it? Join our professional scientists for a lecture and discussion! Start: 00:09; Lecture: 7:35; Expert Q&A Panel: 1:03:55; Fermi Paradox Discussion: 1:31:31
Date: July 10, 2020
Lecturer: Cecilia Sanders
Title: You'll Know It When You See It: Defining, Describing, and Detecting Life in the Universe
Abstract: When scientists search for life in the universe, what in the world are we looking for? What kinds of fingerprints or signatures do living things leave behind on their non-living surroundings, and what tools do we need to detect them? In this talk, I will attempt to define life, give a brief history of life (as we know it) in the universe, and talk through some of the astro-bio-geo-chemical techniques that we use to study it.
Speaker & Panelists:
--Cecilia Sanders is a PhD candidate in geobiology at Caltech, where she studies the geologic record for information about lifeforms on ancient Earth. This is an extension of her previous work as a Masters' student of planetary sciences, when she was intrigued by the preservation problem: how do living things impact the world around them in a way that is preserved in rocks for millions to billions of years? Cecilia tries to answer these questions by measuring and sampling assemblages of ancient, sedimentary rock, and by creating models of the ancient world using living organisms in the laboratory. Her work has taken her to Brazil, Namibia, Turks and Caicos, all over the southwestern United States, and even back home to the fossiliferous cliffs of Maryland/DC. When she isn't doing research, she teaches science to Kindergarten, 1st-, and 2nd-graders in Pasadena Unified Schools and is a community activist for racial justice. She loves to paint, to read fantasy novels, and to run tabletop role playing games for her family and friends. Her favorite foods are passionfruit and doce do leite.
-- Dr. Andreas Faisst is an assistant scientist at the Infrared Processing and Analysis Center (IPAC) at Caltech. He uses the biggest telescopes in the world to study the growth and structure of the first galaxies in the Universe.
--Nicole Wallack is a PhD candidate in planetary science at Caltech. She uses space and ground based telescopes to study the atmospheres of planets around other stars to try to understand how planets form and evolve.
-- Dillon Dong is a PhD candidate in astronomy at Caltech. He uses radio and optical telescopes to study the birth and death of massive stars. In addition to hanging out with his pet bunnies Eloise and Ruben, he has recently been rediscovering his love of bushwhacking and scrambling in the local San Gabriel Mountains.
--Dr. Cameron Hummels is a postdoctoral researcher in theoretical astrophysics at Caltech. He creates supercomputer simulations to study the formation and evolution of galaxies since the Big Bang.

The Accelerating Universe - Robert P Kirshner
Carnegie Observatories 2015 Spring Lecture Series
A Noise Within Theater, Pasadena, CA, May 11, 2015
Dr. Robert P. Kirshner, Clowes Professor of Science, Harvard University
The expanding universe was discovered at Mount Wilson almost 100 years ago. But there is something new! In the past 20 years, astronomers have found that cosmic expansion is speeding up, driven by a mysterious 'dark energy' whose nature we do not understand. Dr. Kirshner, one of today's preeminent astrophysicists, is the recipient of many prestigious awards, including the 2014 Breakthrough Prize in Fundamental Physics (sponsored by Google, among others), as well as the 2014 James Craig Watson Medal of the National Academy of Sciences for 'service to astronomy.'

The Epic of Gilgamesh, Lecture by Andrew George
Andrew George, Professor of Babylonian, School of Oriental and African Studies (SOAS), University of London
The Epic of Gilgamesh is a 4,000-year-old Mesopotamian poem about a hero who embarks on an arduous quest to find the secret of immortality. Preserved on clay tablets in cuneiform script, it is generally considered to be the earliest great work of literature to survive from the ancient world. In this illustrated lecture, Andrew George, author of a prize-winning translation of the Epic of Gilgamesh, explores four themes related to this Babylonian masterpiece: the archaeology of the poem’s recovery, the reconstruction of its text, the story it tells, and its messages about life and death.
Presented in collaboration with the Departments of Near Eastern Languages & Civilizations and Comparative Literature, with the support of the Provostial Fund for the Arts and Humanities, Harvard University

Probing The Distant Universe With Hubble Space Telescope - Part 2
Bullitt Lecture in Astronomy 2019 at the University of Louisville by Dr. Robert Williams, Astronomer Emeritus at the Space Telescope Science Institute. He explores how astronomers have used the Hubble to look back in time to piece together the formation of structure in the universe shortly after the Big Bang, and how small perturbations in the early universe grew to form the giant galaxies that now fill the cosmos. Part 2/9.


Ever since I was young, I already fascinated about the stars, planets and the Universe. How much do we know about them? During my time, when in school we could only study about science especially about the planets and stars by reading books and a few documentary films about it.
Now that I have kids, they are also curious how our world is made and other questions that I alone cannot answer. Other than school and books, I also encourage and support my children in watching National Geographic and other science or educational TV channels. Like my boys they are very fast learners and as other children out there they are learn faster when it is visual. Anything that they watch on TV they tend to understand more and see the visuals.
My eldest when he was just 7 or 8 years old he already watching National Geographic. Once during his school they were discussing about the planets. He has to share in his class what he had learned in watched at National Geographic. The teacher was very impressed and he even described in detailed. Now he is already a teenager he still so interested about science and space.
At home, we often watch only the educational channels because I want them to learn even at home and watching TV. We even watched a show about a tour what is inside the ISS (International Space Station) that is how my kids love to learn more. While watching at FOX HD a commercial showing about COSMOS A Spacetime Odyssey and LIVE From Space! showed up. All of us are so excited and marked our calendar for this opportunity to learn and know more.
Lucky a few days after knowing about the show Cosmos on Fox HD we received an invitation from Nuffnang Philippines for the advance preview of COSMOS A Spacetime Odyssey first episode at the Mind Museum, Bonifacio Global City. We were so excited to come and know what COSMOS is all about.
Ms. Maria Isabel Garcia. Curator of The Mind Museum was so happy that Fox Channel chosen Mind Museum for the exclusive event for the media for COSMOS.
Jude Turcuato (VP for Territory Head – Philippines) for Fox International Channel also showed excitement that COSMOS A Spacetime Odyssey could be previewed here in the Philippines. That everyone will enjoy and learn from the 13 documentary series.
National Geographic Channel and FOX Asia will be airing the Premiere show of COSMOS and LIVE FROM SPACE this March on Fox Channel and National Geographic Channel.
COSMOS: A Spacetime Odyssey, a 13-part docu-series hosted by Neil DeGrasse Tyson. He explains why the COSMOS should not make you feel small.
Neil deGrasse Tyson is an American astrophysicist, author, and science communicator.
The first episode titled “Standing Up in the Milky Way” – Famed astrophysicist Neil deGrasse Tyson shares the birth of Renaissance Italian Giordano Bruno‘s vision of the universe as a limitless expanse of space and time. Then takes an exploration into the Cosmic Calendar, which dates back to the dawn of the Big Bang.
If you only have standard National Geographic Channel and FOX Channel these show will premiere at March 12 at 10pm. However, if you have FOX HD and NatGeo HD it will be on the March 15

The recent live broadcasting from the International Space Station reminded me about how astonishing to think that just decades ago we, the human kind, had our first steps beyond our home planet. It was as if there were no more problems here on earth. Judging by the way we live generally; racing against time and trying to accomplish something in our lives, there is no question that problems will arise anytime. There are probably many things to feel really good about each day, but who really has the time to admire them? Sometimes spending a few moments looking at the world from above and looking at the sky can improve one’s mood in an instant, and maybe nobody can prove it better than the astronauts in space. With the missions that they carry and very limited entertainment on board the station, they do have something great which is the view of the heavens and earth from up there. A break in one’s life is always necessary, no matter the duration, as long as it makes one to appreciate life better, then it works. I’m grateful that the modern science today allow us to understand much better about our universe and admire them at the same time. Personally, thinking about the vastness of this ever-expanding universe, the world, and everything in it can add a little bit of happiness in the soul.
“Do those who disbelieve ever consider that the heavens and the earth were at first one piece, and then We parted them as separate entities; and that We have made every living thing from water? Will they still not come to believe?” (Quran 21:30)
“And the heavens, We constructed with power and skill and verily We are expanding it." (Quran 51:47)
“O society of jinns and men, cross the bounds of the heavens and the earth if you have the ability, then pass beyond them; but you cannot unless you acquire the law.” (Quran 55:33)


This month at Atlas we have had an influx of Japanese translations. As a result of this, we decided to find out a bit more about what the Japanese are up to this month.
Tsukimi Moon viewing is an old Japanese tradition that started when Royal Courtiers and aristocrats would gather beneath the full Moon to recite poetry, and drink sake.
The Japanese hold Tsukimi moon viewing parties in September every year.
These are traditional parties which are held to celebrate the beauty of the Moon.
People gather in places where the Moon can be viewed clearly, hold special feasts which include foods such as tsukimi-dango (dumplings) and of course drink plenty of sake!
The Japanese people follow the time honoured tradition of covering their windows with sprays of susuki (pampas grass) and hagi (bush clover). This is done as an offering to the Moon to make wishes come true.

About the artwork
In ma.r.s., Thomas Ruff sourced his photographs from NASA before digitally transforming them, altering their perspective, and infusing them with color. The photographer demonstrated an affinity for astronomy from an early age, first selecting it as his subject matter in 1989 with the series Sterne—large-scale images of the night sky produced using a specially designed telescopic lens by the European Southern Observatory in Chile.ma.r.s. marks the first series where the artist experimented with 3D image-making. Some of these prints are able to be viewed with 3D eyeware in order to heighten their dramatic effect.

Students in the Oka group use a variety of infrared, near-infrared and visible laser radiation sources to conduct high-resolution high-sensitivity spectroscopy of molecular ions in laboratory plasmas. Their studies are closely related to astronomy, and they also observe the absorption and emission spectra of these ions in astronomical objects. The unifying theme of their studies is the understanding of the quantum mechanics and dynamics of fundamental molecular ions and their behavior in astronomical objects.

New Moon Possibilities for Pisces
By using each of the affirmations below over the moon cycle you are further enhancing your alignment to the energies present. It is in these alignments that we co-create opportunity to fulfil all that is possible.
Do this at the time you write your new moon abundance cheque – before or after is up to you.
Start facing the direction indicated and read the affirmation provided. Continue around in a clockwise direction.
For the Pisces new moon, start in the North.
If you are following the cycle closely, you may like to also use them at quarter and three quarter moons and full moon as a bonus. Click here for the appropriate dates in your timezone.
The affirmations are ideally read while facing each direction. But for those of us who are not so savvy with directions, the illustration engages the energy of the four directions with the energy of a particular Essence of Possibilities for you.
The Essence of Possibilities are eight vibrational remedies and symbols that work together to create fields of energy in which you are supported to fulfil the possibilities in your life.
They come together here, in a combination aligned with the stars and the four directions to support you on the road of abundance.

Indian Space Research Organisation is using the most powerful configuration of its rocket PSLV to launch a communication satellite from Sriharikota on July 15 as it braces for the nearly Rs 200 crore mission. ISRO opted for this step as there is a large unfulfilled and pressing demand for communication transponders.
Earlier also PSLV was used once to launch a small Geosynch satellite Kalpana-1 in 2002 apart from Chandrayaan, a mission to Moon in 2008.
"We wanted to create (transponder) capacity at the earliest. That's why we used the PSLV for the purpose (of launching a communication satellite), and achieve whatever is possible...best possible by a PSLV with XL configuration. That's the most powerful configuration," as per ISRO Chairman K Radhakrishnan.
The GSAT-12 "fast-track" satellite with a mass of 1410 kg, has 12 Extended C-band transponders. It is slated to be injected into space by PSLV-C17 after the launch from Sriharikota spaceport slated between 16.48 hours and 17.08 hours on July 15.
The countdown would start on July 13 at 12.18 hours (Indian Standard Time). The countdown period for the PSLV is 15Hrs and 13 mnts.
Dooordarshan generally transmits the launch activity live, and we have posted a tutorial on what to watch in this transmission in our education blog here


This paper proposes a class of velocity-free attitude stable controller using a novel finite-time observer for spacecraft attitude tracking, which explicitly takes into account control input saturation to assure fast and accurate response and to achieve effective compensation to the effect of external disturbance as well. First, a novel semiglobal finite-time convergent observer is proposed to estimate the angular velocity in a finite-time under external disturbance. Then, a simple global output feedback controller is proposed by adoption of the designed finite-time observer. Rigorous proofs show that the proposed observer can achieve the finite-time stability and the controller rigorously enforces actuator magnitude constraints. Numerical simulations illustrate the spacecraft performance obtained using the proposed controller.


HOW FAR IS 3 BILLION LIGHT YEARS
If you mean the constellation Virgo, that is a direction in the sky, basically. The answer is of no use to you.

Science on the Brain - How far is a lightyear?
Sometimes astrophysicists distinguish between the visible universe, which includes only signals emitted since recombination —and the observable universe, which includes signals since the beginning of the cosmological expansion the Big Bang in traditional physical cosmology , the end of the inflationary epoch in modern cosmology. Pretty cool, I think. To give an idea of 1, light years, if you were driving at a law breaking speed of mph, it would take you nearly 11 billion years to get there.

- Astronomers say they have found the most distant galaxy in the universe, called EGS-zs, measured at
Lets see if I can't manage to get that on a managable scale, huh? An opposite effect works on the galaxies already within a cluster: The most famous horizon is the particle horizon which sets a limit on the precise distance that can be seen due to the finite age of the universe. If the whole galaxysuddenly winks out and disappears tomorrow, we won't know about it for another 13billion years.
And a lighthour is 60 lightminutes, or about million miles. The density of ordinary matter, as measured by Planck, is 4. Since light moves atmiles per second, a lightsecond ismiles.
Using a longer yard stick, so to speak, helps keep the numbers at least manageable. For example, galaxies behind a galaxy cluster are attracted to it, and so fall towards it, and so are slightly blueshifted compared to how they would be if there were no cluster On the near side, things are slightly redshifted.

Moon From Space
This image provided by NASA was taken on Sunday, July 31, 2011, when Expedition 28 astronaut Ron Garan aboard the International Space Station looked out his window, this is what he saw: the moon. And, he saw it 16 times. For Garan and the rest of the station crew, this extraordinary event is a daily occurrence. Since the station orbits the Earth every 90 minutes, each day the crew experiences this about 16 times a day.

The black hole measures about 40 billion km across – three million times the size of the Earth – and its described by scientists as “a monster”.
The black hole is 500 million trillion km away and its photographed by a network of eight telescopes across the world.
Details now published today in Astrophysical Journal Letters.
Its captured by the Event Horizon Telescope (EHT), a network of eight linked telescopes.
“What we see is larger than the size of our entire Solar System,” he said.
“It has a mass 6.5 billion times that of the Sun. And it is one of the heaviest black holes that exists. It is an absolute monster, the heavyweight champion of black holes in the Universe.”

PENDLETON – The Delta Aquarid meteor shower peaks in the early morning hours of Wednesday and Thursday. It’s considered to be a modest display.
“It’s kind of an average shower that can produce up to 20 meteors an hour at its peak,” National Weather Service Hydrologist Marilyn Lohmann said. “It’s produced from debris left behind from comets Marsden and Kracht.”
Friday’s full moon is waning, but could still cause a problem with viewing the meteors.
“Its (the moon’s) glare might block some of the meteors, but if you’re patient and out in a real dark location, you should be able to catch a few good ones,” she said.
The Delta Aquarid shower is considered a warmup for the Perseid meteor shower which peaks on Aug. 11, with an expected average of 50 meteors an hour on that date.

The first Full Moon of 2020, the Wolf Moon is here! According to the Old Farmer’s Almanac, the January Full Moon was dubbed the ‘Wolf’ Moon by Native Americans because it occurred at a time of year when wolves would be howling with hunger. The bright full moon light can also produce rainbows at night which are sometimes caused by the refraction of light through ice particles in high altitude clouds. They are called lunar rainbow or 'moonbow'. The uniqueness of 2020 is there are 13 full moons including two full moons in the month of October i.e. Harvest moon and the Blue moon.

Live Music + Film
Directed by Hanns Walter Kornblum with a score performed live by Coupler
In 1925, German director Hanns Walter Kornblum set out to create a film unlike any that had come before. His aim was a film that would serve as both a summation of all the astronomical knowledge available at the time and a dreamy investigation of what wonders might await humanity with the advent of space travel.
With the help of fifteen special effects technicians and nine cameramen, Kornblum’s film is a technical marvel, one that revels in the beauty and mysteries of the universe, reminiscent of Carl Sagan’s Cosmos more than 50 years later. The film will be accompanied by a live scored performed by Coupler, a Nashville-based ambient electronic group. 1925, Germany, DCP, silent with live score, 91 minutes. Appropriate for all ages.

Spotlight on Dark Matter/Energy Drive
The dark matter and energy drive works to advance canon.
In order to hop between the two main universes, I needed a semi-mysterious means of getting around. Without having to be dependent upon a worm hole, or cranking the engines up to crazy numbers like Warp 50, I needed something else.
In order to fix this problem, and to add some drama and, admittedly, some technobabble to the HG Wells series, I hit upon the idea of a dark matter or dark energy drive. I have called it both, although I realize the terms, in truth, are not interchangeable. Because dark matter and dark energy are a large percentage of our universe (our current understanding), fuel would be abundant. A time traveler would be able to gather it pretty much whenever and wherever he or she needed, so long as the collector was working properly.
I also gave it a bit of a fun spin, the sort of thing that engineer Kevin O’Connor in particular would love. I decided that the encroachment of dark energy was a byproduct of the aging of the universe (the graphs at right would seem to support that hypothesis), but that using the drive would, in a slight way, reverse it. And that would put off the eventual destruction of the universe by a few seconds or so.
How it Works (Kind of)
The concept is, essentially, that the time traveler creates a mini-worm hole at will. The ship then flies through it and enters the other universe. In Multiverse II, Levi Cavendish mentions to Maren O’Connor that it’s possible to travel to other universes by simply adjusting the radiation band being aimed at. This would include #49, the home of the best pumpkin pie in any universe.
This bit of technology will be back. I guarantee it.

I think the thing I'll miss the most about college is being able to go outside and look at the stars
I’m going to be in a big city with tons of light pollution and I won’t be able to see them :( And I’ll miss being able to walk around at night in my neighborhood. Don’t get me wrong, I’m excited to go to college and take the next step in my life, but I still like the freedom of being able to come and go through this town because it’s not that dangerous. I guess I’ll just be able to experience different kind of stars. The ones provided by city lights that stay on all night and flicker on and off. A modern day starry night, instead of the stars being up in the sky, they’re on the ground with skyscrapers and buses.
This isn’t logical, this doesn’t make sense. Fuck feeling, this sucks so bad. I can’t take the fact that you control my mood. One good compliment from you and i feel like i’m floating and if you ignore a text for more than a few minutes i feel like i’ve fucked everything up. I hate this, I hate this. The worst part, I can’t even blame you because you’re not doing this to be cruel or mean, you are just being yourself. I hate that I’m acting like a stupid love crazed teenage girl. I have never been like this. Somebody make it stop please.

Mars, The Read Planet
Our nearest solar neighbor, Mars, has long been the subject of exploration and research. From the very beginning humanities’ interest in space has been about making a voyage into the unknown, to satisfy our curiosity, to take advantage of scientific opportunity, and to display our spirit of exploration. Why else would our robotic explorers have such adventurous names if not to reflect our own nature among the stars? These books seek to highlight our progress and achievement as research on the Red Planet continues and to look at our ongoing journey into space. From Mars to the Jovian Moons, Jupiter, and beyond our very own solar system!
In its eerie likeness to Earth, Mars has long captured our imaginations-both as a destination for humankind and as a possible home to extraterrestrial life. It is our twenty-first century New World; its explorers robots, shipped 350 million miles from Earth to uncover the distant planet’s secrets”. This book explores the robotic space exploration of the Mars rover Curiosity as well as the incredible journey it took to get there.
This book tells the stories of eleven space exploration voyages. Beginning with missions to Mars and moving beyond it shows, with vivid illustrations, the progress we have made scientifically with unmanned space exploration.
Science Fiction meets reality as the rover curiosity braves the harsh conditions of Mars on its indefinite mission “to determine the planet's "habitability” (NASA. Web). Mars up close offers a detailed insider look at the journey and technology of the curiosity mission, as well as the trial and tribulations it took to reach a planet thirty-five million miles away from home.


New Delhi: In a special announcement, American space agency NASA has revealed names of the crew members assigned for the upcoming space station expeditions.
According to NASA, Feustel will launch in March 2018 for his first long-duration mission, serving as a flight engineer on Expedition 55, and later as commander of Expedition 56. Epps will become the first African American space station crew member when she launches on her first spaceflight in May 2018. She’ll join Feustel as a flight engineer on Expedition 56, and remain on board for Expedition 57.
“Each space station crew brings something different to the table, and Drew and Jeanette both have a lot to offer,” said Chris Cassidy, chief of the Astronaut Office at NASA’s Johnson Space Center in Houston. “The space station will benefit from having them on board.”
Feustel and Epps will be added to the long list of distinguished astronauts who have been a part of space missions on the ISS since November 2000.
NASA’s orbiting laboratory houses 3 crew members per expedition and since the missions overlap, there are a total of 6 crew members present inside the ISS each time.
At present, the space station is host to six astronauts as a part of Expedition 50 and 51, which include NASA astronaut Shane Kimbrough and Roscosmos’ Sergei Ryzhikov and Andrei Borisenko (Expedition 50), along with NASA astronaut Peggy Whitson, European Space Agency’s (ESA) Thomas Pesquet and Roscosmos’ Oleg Novitskiy (Expedition 51).

GOCE completes its mission
After nearly tripling its planned lifetime, the Gravity field and steady-state Ocean Circulation Explorer – GOCE – has completed its mission and will soon reenter our atmosphere.
With a sleek, aerodynamic design responsible for it being dubbed the ‘Ferrari of space’, GOCE has mapped variations in Earth’s gravity with extreme detail. Scientists further exploited these data to create the first global high-resolution map of the boundary between Earth’s crust and mantle – called the Moho – and to detect sound waves from the massive earthquake that hit Japan on 11 March 2011, among other results.
In mid-October, the mission came to a natural end when it ran out of fuel and the satellite began its descent towards Earth from a height of about 224 km.
All of the latest information on the mission’s scientific results and reentry can be found here:
8 November 2013
Reentry of GOCE into Earth’s atmosphere is predicted to occur during the night between Sunday and Monday. Break-up of the spacecraft will occur at an altitude of approximately 80 km. At the moment, the exact time and location of where the fragments will land cannot be foreseen.
The estimate is based on the results of detailed analysis, taking in to account a number of changeable factors including spacecraft orientation, the functioning of the attitude control system, as well as solar and geomagnetic activity.
Updated predictions will be communicated on this page and in the related blog.


A cold night, danger of bear attacks and three crazy souls braving it for a night sky photograph (2 shutter-crazies and me on the lookout for bears) marked our hunt for yet another elusive night sky shot. Grand Teton National Park seemed like a great spot for viewing and getting great shots of the Milky Way that September. The park (in most places) has minimal light pollution and the Milky Way would rise above the rocky edges of the Tetons Mountains.
Night sky shooting is very tricky for various reasons – you need a moon but not a very bright one, you need a few clouds but not a cloud cover, no light pollution, a good spot facing the right direction, and last but not the least being able to improvise as no matter how set you are there will be choices to make in the camera settings! But this is a travel article and not a photography one (the title notwithstanding), I will not go into more technical camera details.
Viewing the night sky and photographing it are completely different experiences. The eyes saw a lot more – several shooting stars and the sheer expanse of the star studded canopy over us, which is impossible to capture even with the best camera.


Virtutone net revenues reached $43,216,403 for the second quarter of 2014, an increase of $34,555,976 or 399 % compared to the same period a year earlier, and an increase of $14,853,436 or 52 % compared to the first quarter of 2014
........ Here is what happened, when astronomers pointed the& nbsp;Hubble Space Telescope at what appeared to be absolutely nothing, and left it there for 10 days, and the again for 11 days. Then they made the images into a 3-D presentation. The results are, well, "incredible" and may change people's perception of our importance in the universe.


Exhibition Development Group
NCIL staff have over fifteen years' experience producing both large and small traveling exhibitions on a variety of STEM topics: space weather, planetary science, astrobiology, and earth science. The Exhibition Development Group oversees all phases of exhibit planning and production from concept generation through fabrication. We also manage the national tour of our traveling exhibitions. NCIL exhibitions rely on contributions from the Digital Learning Group, Professional Development Group, and Learning Research and Evaluation Group.
NCIL's exhibitions incorporate hands-on, age-appropriate components suitable for all age groups and learning styles. We target underserved communities (e.g. rural) and the institutions that serve them, such as small science centers and libraries. Our exhibitions benefit from strong partnerships with STEM professionals, educators, artists, designers, and fabricators. Recent focus has been on designing inquiry-based learning experiences for digital platforms such as a Microsoft Surface, multi-touch tables, and globes.
An NCIL exhibition is much more than just the traveling exhibit. Exhibit education programs include enrichment activities, in-person and virtual workshops (for both classroom and museum educators), downloadable science resources, and connections for bringing scientists and other public programs to host venues. Classroom materials are standards-based and aligned with the exhibit so that teachers can do the activities in their classroom either before or after a field-trip. We also develop interactive websites that extend the scope and reach of our exhibits.

On October 25, a day after Laxmi Pooja a partial Solar Eclipse (Surya Grahan) is set to occur in some parts of the globe. The eclipse will be visible in the regions covering Europe, the Middle East, North-Eastern parts of Africa, Western Asia, the North Atlantic Ocean, and the North Indian Ocean.
People in parts of India will be able to witness the phenomenon, except a few states in the NorthEast region. According to PTI, the eclipse will begin in Iceland at around 02:29 PM (IST) and will end at around 06:32 PM over the Arabian Sea. It will be seen at its maximum from Russia at 04:30 PM.
In India, the Solar Eclipse will visible from 04:29 pm and will end with the sunset at 05:42 pm. The maximum eclipse time will be at 05:30 PM. The total duration of the partial solar eclipse is 1 hour, 39 minutes and 31 seconds. Since it’s a partial solar eclipse, the fraction of the Sun’s disc that the Moon will cover will differ depending on what part of the planet one views the phenomenon from.
The eclipse will be visible for the longest in Gujarat’s Dwarka and for the shortest time in West Bengal’s Kolkata. A few other cities that will witness the eclipse longer than an hour are New Delhi, Mumbai, Ahmedabad, Surat, Pune, Jaipur, Indore, Thane, Bhopal, Ludhiana, Agra, Chandigarh, Ujjain, Mathura, Porbandar, Gandhinagar, Silvasa, Surat, and Panaji.
The states where the eclipse will be visible for less than an hour are Hyderabad, Bengaluru, Chennai, Lucknow, Kanpur, Nagpur, Visakhapatnam, Patna, Mangaluru, Coimbatore, Ooty, Varanasi, and Thiruvananthapuram. However, the eclipse will not be visible from Aizawl, Dibrugarh, Imphal, Itanagar, Kohima, Silchar, and Andaman & Nicobar Island.
In the 21st century, where every fact and myth is just a click away, people still turn to ignorance owing to either traditions or superstitions. Now, when the Moon passes in between of the Earth and the Sun and all three objects are in line, a solar eclipse takes place on a new moon day. When the lunar disc partially obscures the solar disc, it is known to be a partial solar eclipse.
Here are a few dos and don’ts that should be taken care of during eclipses:
- If you want to watch the eclipse, make sure to use the right filter like black polymer or aluminized Mylar on either the telescope or the glasses used for viewing
- Always wear protection in the eyes whenever planning to view the eclipse, even through a telescope
- Always drive with your headlights on during the eclipse
- Never, ever watch the eclipse with the naked eye, not even for a second.
- Do not use regular sunglasses to view the eclipse
- Avoid using any kind of camera to record the eclipse
- Never leave the kids unsupervised during an eclipse
Again, the above were scientific dos and don’ts that are proven, which scientist have been advising to follow for decades now.
However, there are other self-proclaimed ‘facts’ that religions, traditions(around the world) and mythology have stated, here are some myths and the corresponding facts that people should pay heed to:
Eclipses or grahan are considered to be inauspicious in the Hindu mythology, as they have been in mythologies around the world. However, since this phenomenon is taking place in the proximity of Diwali, we will look at it from the point of view revolving around the Hindu mythology.
The sun, which is worshipped as a major life force in the universe, disappears during the solar eclipse, making it an omen of all things evil. Naturally then, a number of rituals are conducted to minimise the negative effects of this natural phenomenon.
Why is it considered inauspicious? To answer this question one has to know about the mythological story of the demon Rahu:
The Sun, the Moon and the demon, Rahu
The story of eclipses in Hindu mythology dates back to the samudra manthan, as described in both Bhagawat and Vishnu Puranas. After the amrit or elixir of immortality was churned out of the ocean, the Devas used the apsara Mohini to trick the Asuras out of its share. One of the Asuras, Svarbhanu, disguised himself as a Deva, and sat between the Sun and the Moon for a drink of the elixir.
When Vishnu came closer, the Sun and the Moon revealed that Svarbhanu was a demon. By this time, however, Svarbhanu had already sipped on the drink. Vishnu immediately cut off his head, but since the demon had already swallowed a bit of the nectar, his head became immortal.
The head, known as a separate entity called Rahu (the detached body came to be known as Ketu), then swore vengeance against the Sun and the Moon for depriving him of the elixir. So, from time to time, Rahu catches up with the Sun and the Moon, and swallows them, and according to the mythology, this incident doesn’t last long because Rahu has no hands to grab onto these two celestial gods.
This is where the term “Rahu Kaal” comes from, and this period of time is considered highly inauspicious.
Superstitions surrounding the eclipses state that harmful agents are at play during these periods, and so, every action should be guided by the utmost caution during eclipses. The absence of the sun’s rays can increase the amount of bacteria and germs in the atmosphere, thereby polluting people.
Here are some of the myths during solar eclipses:
1. Eclipse and piety:
Worshipping or touching gods is prohibited during eclipses. Temple doors usually stay closed during eclipses. After the eclipse ends, the idols are supposed to be washed with Ganga water to purify them.
2. Eclipse protections:
Meditation, chanting hymns or mantras and singing devotional songs during an eclipse are supposed to protect one from the evil effects.
3. Eclipses and food:
Food should not be cooked during the eclipse, which may cause poisoning. Leftovers are finished off before the period of the eclipse. Some people in India leave tulsi or Indian basil leaves on cooked food items, and cover them to keep them safe and devoid of poison.
4. Daily routines:
Sleeping, urination, defecation, sexual intercourse and makeup are also prohibited during the eclipse.
5. Pregnant women and misscariages/labour complications:
Pregnant women are considered to be especially susceptible to the evil forces during eclipses. Not only are they supposed to abstain from activities like cutting vegetables and stitching clothes, but in some parts of India, they’re not even supposed to sit with their legs crossed.
Bathing is advised before the eclipse and after the eclipse is over, people are directed to take a bath, and change into fresh and clean clothes. Sprinkling of Ganga water or taking a dip in the Ganga is also supposed to wash away the evil brought by the eclipse.
1. Eclipses will poison any food that is prepared during the event.
NASA scientists debunk the myth saying, “Related to the false idea of harmful solar rays is that during a total solar eclipse, some kind of radiation is produced that will harm your food. If that were the case, the same radiations would harm the food in your pantry, or crops in the field. The basic idea is that total solar eclipses are terrifying and their ghostly green coronae look frightening, so it is natural to want to make up fearful stories about them and look for coincidences among events around you. If someone is accidentally food-poisoned with potato salad during an eclipse, some might argue that the event was related to the eclipse itself even though hundreds of other people at the same location were not at all affected.”
2. Eclipses are harbingers of something very bad about to happen.
“A classic case of what psychologists call Confirmation Bias is that we tend to remember all the occasions when two things happened together, but forget all of the other times when they did not. This gives us a biased view of causes and effects that we remember easily, because the human brain is predisposed to looking for, and remembering, patterns that can be used as survival rules-of-thumb. Total solar eclipses are not often recorded in the historical record, but they do tend to be recorded when they coincide with other historical events. For example in 763 B.C., early Assyrian records mention an eclipse in the same passage as an insurrection in the city of Ashur, now known as Qal’at Sherqat in Iraq, suggesting that the ancient people linked the two in their minds. Or when King Henry I of England, the son of William the Conqueror, died in A.D. 1133, the event coincided with a total solar eclipse. With a little work you can also find numerous cases when something good happened!” NASA asserts.
3. If you are pregnant you should not watch an eclipse because it can harm your baby
“This is related to the previous false idea that harmful radiations are emitted during a total solar eclipse. Although the electromagnetic radiation from the corona, seen as light, is perfectly safe, there is another form of radiation that travels to Earth from the sun. Deep in the solar interior where nuclear fusion takes place to light the sun, particles called neutrinos are born, and zip unimpeded out of the sun and into space. They also pass through the solid body of the moon during the eclipse and a second or so later reach Earth and pass through it too! Every second, your body is pelted by trillions of these neutrinos no matter if the sun is above or below the horizon. The only consequence is that every few minutes a few atoms in your body are transmuted into a different isotope by absorbing a neutrino. This is an entirely harmless effect and would not harm you, or if you are pregnant, the developing fetus,” NASA reveals.

Wow. This wasn’t expected. On the anniversary of the moon landing in 1969, NASA officials stated that they “couldn’t find” the original footage of the lunar walk because it was likely taped over for another mission. They just released new restored footage of the moon walk based on the original broadcast. No explanation as to why no one recognized the first walk on the moon as something that should be saved! To cut costs, the Apollo 11 landing was taped over, but is now costing NASA over $200,000 to restore the broadcast footage.
Sometimes cutting corners isn’t always the best plan. What a huge oversight!


Lisa Sammut: How the earth will approach you
- When 28 Jun - 8 Sep 2024
Cnr of Oxford St and Greens Rd, Paddington. NSW 2021
WED TO FRI 10AM–5PM; SAT TO SUN 12–5PM
Working across sculpture, video, and installation, Lisa Sammut’s practice oscillates between notions of cosmic perspective, belonging, connection, and time. ‘How the earth will approach you’ brings together recent works that explore the cosmos as a framework for understanding the dynamics, relations, and dimensions of our personal and social worlds.
Sammut draws on historic astronomical diagrams, illustrations, and manuscripts observing omens in celestial phenomena. Works also borrow from the visual language and performative qualities of GIF animations that document the movements and behaviours of comets. The exhibition brings human and cosmic worlds into close relationship, where understandings of the universe are formed in direct relation to ourselves. It considers human life in connection to transitions and cycles in the cosmos; the circular, orbital, elliptical, and eclipse.
The exhibition loops between the earthly and otherworldly, taking shape in the knowledge that our fate is intertwined with the events and laws of the universe. At the centre of the exhibition is the immersive installation FULL CIRCLE which incorporates objects, light, and moving image, with suspended structures intended to be viewed as drawings in space. It questions the notion that life moves in a straight line. Like the cyclical trajectories of comets, the circular perspective presents an alternate view, where a life is defined by a departure and a return. Linking cosmic and human timespans, Sammut proposes that the visualisation of a comet’s elliptical path illustrated within a simple image, brings a strange comfort.
Sammut has recently turned towards the medium of handmade glass, creating intimate, hand-held objects that speak to ideas of expanse and magnitude. Conceived as ‘cosmic eggs’, the glass sphere has become a recurring motif in recent projects, where it reflects, flips, warps, and distorts its surrounding environment. The sphere or ‘crystal ball’ is culturally understood to be a tool for self-reflection, a way to grasp the indefinite and unclear, to glimpse our future and know our fate. Overlaying celestial phenomena and human narratives, Sammut investigates themes of otherness, power, and agency, using the metaphorical qualities of interplanetary movement to reconsider the role of the individual, and the sway of the collective.

Works in this exhibition were developed during a residency at Canberra Glassworks in 2023, supported by an Arts Project grant from Creative Australia.

For my undergraduate dissertation I undertook a group project to design a small satellite power supply. The deliverable product was a populated and tested PCB designed to fit the demanding physical constraints imposed by the satellite. The main features of the power supply include solar energy harvesting and battery monitoring along with six individual supply lines, each complete with monitoring and protection. The project also involved a lot of background research into cosmic effects on electronics.
I took the lead PCB design role and was responsible for physical design, component choice, layout, and thermal management. The final product passed rigorous electrical, vibrational and thermal testing and is awaiting deployment into space as part of the University of Southampton Small Satellite Project (at time of writing, September 2016).
