[collection introduction]: in ancient times, people often regarded meteorites as sacred objects. For example, the ancient Romans regarded meteorites as messengers of God. They built a bell tower at the place where meteorites fell. Hungarians carried the meteorite into the church and locked it with chains to prevent the "gift of God" from flying back to heaven. There is also a meteorite in Mecca, the holy land of Islam, which is regarded as a "holy stone". In some countries with ancient civilizations, meteorites are often used as funeraries for emperors and dignitaries.
Meteorite is a powerful weapon to ward off evil spirits and block evil spirits in China! The magnetic field energy is very strong and the frequency is very high. Evil spirits, ghosts and demons are not allowed to get close. China's meteorite culture originated 14600 years ago, which we call the period of prehistoric civilization. This era has produced a large number of meteorite art objects, which are diverse and rich, and have high artistic charm and aesthetic value. This prehistoric meteorite art is recognized by countries all over the world as a rare art beyond African wood carving. These meteorites remove religious, political, historical, cultural, scientific and other factors. The unique mysterious and powerful energy of the meteorite itself is considered to have the dual functions of restraining houses and avoiding evil spirits. The preservation of this meteorite is almost perfect. After maintenance, the surface has shown a bright glaze color, and the touch of the upper hand is smooth and flat.
Meteorites are very rare foreign space resources and have extremely important scientific research, collection and economic value. There are many kinds of meteorites. They carry a lot of cosmic information. They are valuable material materials for human beings to study the formation and evolution of the universe, solar system and earth life, as well as cosmic disasters and special mines. They also provide a rare carrier for people to study extraterrestrial life. They are regarded as cultural relics specimens with important scientific and cultural values. Meteorite refers to the meteorite debris falling to the ground, which is composed of iron, nickel, silicate and other minerals, also known as meteorite. It also refers to meteorites with more or all stones. A large number of organic substances such as ammonia, nucleic acid, fatty acid, pigment and 11 kinds of amino acids have also been found in meteorites with high carbon content. Therefore, it is believed that the origin of life on earth is closely related to meteorites.
陨石又称“陨落的星星”，是由未燃烧的岩石、铁或铁和石头混合而成的碎片，它们从地球或其他行星的表面飞离，作为宇宙流星或地球外轨道位置的尘埃碎片。因为陨石是来自外层空间的，陨石判定真假是需要仪器鉴定的，肉眼只起辅助作用。 大多数陨石来自火星和木星之间的小行星带，少数来自月球和火星。 陨石大致可分为石质陨石，铁质陨石，石质铁质陨石混合而成。陨石含有丰富的太阳系天体形成和演化的信息，其实验分析将有助于探索太阳系演化的奥秘。 陨石是由地球上已知的化学元素组成的，在一些陨石中发现了水和各种有机物。 这是一个假设的基础，即地球上的生命是陨石向地球传播的生命的种子。 通过测量陨石中各种元素的同位素含量，可以计算陨石的年龄，计算太阳系的形成周期。 陨石可以是小行星、行星、大型卫星或彗星的碎片，它们可以从这些物体中携带原始信息。
Meteorites, also known as "falling stars", are fragments made of unburned rock, iron or a mixture of iron and stone. They fly away from the surface of the earth or other planets as cosmic meteors or dust fragments in the orbit outside the earth. Because meteorites come from outer space, the determination of the authenticity of meteorites requires instrument identification, and the naked eye only plays an auxiliary role. Most meteorites come from the asteroid belt between Mars and Jupiter, and a few from the moon and Mars. Meteorites can be roughly divided into stone meteorites, iron meteorites and stone iron meteorites. Meteorites contain abundant information about the formation and evolution of celestial bodies in the solar system. Their experimental analysis will help to explore the mystery of the evolution of the solar system. Meteorites are composed of known chemical elements on earth. Water and various organic substances have been found in some meteorites. This is the basis of a hypothesis that life on earth is the seed of life transmitted by meteorites to the earth. By measuring the isotopic content of various elements in meteorites, we can calculate the age of meteorites and the formation cycle of the solar system. Meteorites can be fragments of asteroids, planets, large satellites or comets. They can carry original information from these objects.
The surface of this meteorite is covered with pits of different sizes and depths, namely melting pits. Many meteorites also have shallow and long strip gas seals, which may be left by the shedding of low melting point minerals. The weight of this meteorite reaches 1305.8 grams. When the meteorite passes through the atmosphere, the extremely high temperature causes the surface of the meteorite to melt, producing a layer of micron to millimeter glass layer, which is the molten shell. When meteorites exist on the surface for a long time, their molten crust is easy to be weathered and disappear. This meteorite has weak magnetism because it contains a small amount of iron. The appearance of stone iron meteorites is very similar to the rocks on the earth. It will be a little heavier than the rocks with the same volume. Stone iron meteorites generally contain a few percent of iron and are magnetic. You will feel it if you try with a magnet. Stone iron meteorite is the most common meteorite, although its number of falls is large, accounting for more than 92% of the total falls. The air print is a trace similar to finger print produced by meteorite in high altitude and air flow, which is called air print. It's like the mark left by your thumb on a piece of clay. The question of whether there is a gas seal has been paid attention to by many experts and Martian meteorite lovers.
Frog is a kind of spiritual animal. Since ancient times, many places and nationalities in China regard frog as rain god or thunder god, which means that it can bring wealth and auspiciousness to people. The shape of this stone meteorite is very like a frog. Its head is triangular, raised high, and its body tilts forward. There is a circular protrusion under its forehead, which is just like an air bag. It looks like a pleasant frog chirping. He looked like a real frog, ready to jump to arrest insects. The frog's modeling, with protruding eyes and a fine seam between the upper and lower jaw lips, properly outlines the frog's mouth. It looks vivid and interesting. Its abdomen is round and its back is wrinkled clearly, accompanied by brown spots. It looks exquisite and vivid. What's more interesting is that looking at the whole appearance of the strange stone, the frog is light and tall, with clear outline, both shape and spirit, and lifelike. Not only that, the size of this meteorite frog is also consistent with that of a real frog. I think this frog will give the viewer a strong visual impact in its shape and appearance. After watching, people are amazed at the uncanny workmanship of nature, and its appreciation space is immeasurable!

The earth revolves around its own axis once every 24 hours. As a result, those in the equatorial region are orbiting the earth at a rate of 1600 kilometers per hour. Moreover, the earth revolves around the sun at a speed of 110,000 kilometers per hour. Again, the sun with its planets orbiting the galaxy at a speed of 8 lakh 28 thousand kilometers per hour. We can’t feel this speed even after running at such a huge speed. But we can also understand by traveling at a trivial speed compared to it by bus or train or other vehicles. There is a lot of stress on our body. But why?
When a bus or train is moving, it does not move at a balanced speed in most cases. That is, its velocity changes over time. For example: a bus now travels at maybe 60 km / h, then it travels at 70 km / h. Then we can understand the change in its velocity. The rate of change of velocity over time is called acceleration. We can’t feel the speed. We can feel the rate of change of velocity i.e. acceleration. If the velocity does not change then no matter how much the velocity is, it will not be felt and it will not have any effect on our body. Man-made all-moving objects move more or less at unequal speeds, meaning that there is always some acceleration. Again, even if the value of velocity is fairly balanced, its direction changes. All of us who have read the very basic discussions of physics in school know that acceleration occurs when the value or direction of velocity or both changes. So even if the value of velocity is balanced and the direction changes, we can still feel that speed. Every man-made vehicle changes direction more or less. Not only this, with the help of fire you can do welding. But if the value and direction of velocity are constant then we will not feel it. For example, ships often move at a steady speed in the still sea. So the moving ship lying in the cabin of the ship will feel stable to us.
On the other hand, all the motions of the earth itself are very balanced, so their motions cannot be felt. Even then, if the various objects around us on earth were moving at different speeds, we would still be able to understand the velocity, due to the change in position of one relative to the other. But everything on the earth’s surface is moving at the same speed as the earth. So there is no way to understand the speed of the earth. By now you may be thinking that no motion of the earth is linear and almost all kinds of motion are rotational. Since the direction of the rotating earth’s velocity is constantly changing, then it is possible to feel it. In this case, the earth’s motions are rotational, but their curvature is very low. The larger a circle, the less its curvature. This curvature of the earth relative to man can be taken as a straight line. In that case, the effect of acceleration on us will not be felt.
The previous people were confused because they could not feel the motion of the earth. People think that the earth is stationary and seeing the change of position of different objects in its sky, they think that the earth is the center of the universe and other objects revolve around the earth. That belief began to be shattered only four centuries ago, with the introduction of telescope observations of the sky. The greatest contribution of the scientist Galileo.


A new era blasts off
Private space flight raises the question: Can private companies improve other government services?
The successful return of the Dragon-X space cargo capsule recently shows that the era of private commercial space flight has begun.
The unmanned capsule was built and operated by Space Exploration Technologies (Space-X), a 10-year-old company owned by Paypal founder and billionaire Elon Musk. Dragon-X carried 500 kg of supplies and equipment to the International Space Station and returned with about 650 kg of retired equipment and scientific samples.
It used to be the accepted wisdom that space flight was the province of governments: the resources (money and manpower) needed for space missions were so expensive that only big federal agencies could afford them. Space-X's Musk has turned this idea on its head.
The National Aeronautics and Space Administration (Nasa) itself has sought to move space flight to private companies in recent years. Its space shuttles flew their last missions in 2011; American astronauts currently board Russian and European spacecraft to go to the International Space Station. Space-X is vying for a $1.6 billion Nasa contract for 12 supply missions to the International Space Station. It also has plans to start ferrying astronauts into orbit. Nor is it the only one. There is healthy competition among private companies to see who gets there first.
In the 1960s, space became a theatre of the Cold War as superpowers United States and the
raced each other to prove technical superiority. By the end of the decade,
American astronauts Neil Armstrong and Buzz Aldrin had
walked on the Moon. It was a triumph of
engineering: the USSR had won the space race. United
Four decades later, amidst a weak economy, there is no appetite among American politicians for the big taxpayer-funded spending Nasa's manned space flights need.
programme is particularly in dire straits. While countries like Russia India and have space aspirations, and
have had good successes in recent years, today the most interesting proposals
are coming from the private sector. China
Space has gone back to being the province of obsessed dreamers — which is where it all started. Early rocketry and space flight pioneers such as Robert Goddard and Hermann Oberth were ins-pired by science fiction. They conducted rocketry experiments as kids and constantly thought about how humans could get rid of our earthly shackles. Few who knew them as kids probably thought their dreams would be realised. Yet, man not only went into orbit, but walked on the Moon in the 20th century.
Today, Musk wants to retire on Mars, and Virgin Galactic's Richard Branson plans to offer space tourism flights. Film director and explorer James Cameron has announced he is interested in mining asteroids for precious metals.
Private entrepreneurs have always advanced new technologies, even if they are not the original inventors. Look at the history of the railway. A working steam locomotive was developed by Richard Trevithick in
years before George Stephenson built
the Stockton and Darlington
railway. But it was Stephenson who was entrepreneurial enough to make trains
English inventor Joseph Swan constructed a working incandescent light bulb years before Thomas Alva Edison, who is widely credited with its invention. Swan even set up a com-pany to market his invention. But it was
entrepreneurship and scheme for electricity distribution that eventually won
the day. (Swan's company later merged with Edison's.)
Private entrepreneurs can often reduce costs drastically. Musk has estimated that Space-X can launch one kg of payload into orbit at about one-ninth Nasa's cost.
At this point, it is still early days for private commercial space flight. But there is no doubt that we are witnessing the beginning of a new era, when private corporations will make space their own turf. Space-X is working on creating manned space taxis next. While Came-ron's avowed desire to mine asteroids may sound more in the realm of science fiction than science fact, it might indeed be technically feasible (although the jury is still out on the economic benefits, because any precious metals mined this way would be plentiful enough to see their prices drop).
Science fiction author Arthur C Clarke predicted shortly before his death in 2008 that commercial spacecraft would become a reality within the decade. Space-X was making plans then. He also told me that he believed thousands would travel into orbit in the next 50 years, and then people would go to the Moon and beyond on private spacecraft.
It is worth asking what private entrepreneurs could do for other large public enterprises. For instance, could a private enterprise improve rail service in
? Would a
private corporation do a better job than Indian Railways of running, say, a
high-speed Delhi-Mumbai rail corridor? India
And what about
? Should the
government look into privatising the postal service, or at least sections of
it? Anyone who goes to a post office in India recognises that there are
things the government doesn't do particularly well. India
When one thinks about it, there are probably only a few things that governments should always do. National security is of course the obvious example. Health monitoring and national healthcare may be another. Most things that we have thought were the province of governments can be done just as well by public-private partnerships — or just private enterprises. By sending a rocket to space, Space-X has just proven it to us.

This new Hubble image is the best-ever view of the Tarantula Nebula, a region full of star clusters, glowing gas, and dark dust. Astronomers are exploring and mapping this nebula as part of the Hubble Tarantula Treasury Project, in a bid to try to understand its starry anatomy. The Tarantula Nebula is located in one of our closest galactic neighbours, the Large Magellanic Cloud.
Spiral Galaxy NGC 5033
Magnificent island universe NGC 5033 lies some 40 million light-years away in the well-trained northern constellation Canes Venatici. This telescopic portrait reveals striking details of dust lanes winding near the galaxy’s bright core and majestic but relatively faint spiral arms. Speckled with pink star forming regions and massive blue star clusters, the arms span over 100,000 light-years, similar in size to our own spiral Milky Way. A well-studied example of the class of Seyfert active galaxies, NGC 5033 has a core that is very bright and variable. The emission is likely powered by a supermassive black hole. The bright nucleus and rotational center of the galaxy also seem to be slightly offset, suggesting NGC 5033 is the result of an ancient galaxy merger.

Trip to Shamakhi Astrophysical Observatory
On April 30, 2017, grades 4 to 9 students visited the Shamakhi Astrophysical Observatory were they discovered and explored different types of telescopes. Students were shown the earliest telescopes, their functions, and their importance in finding out the detailed features of stars, as well as other planets in the galaxy. The trip was followed by a picnic. This trip was organized as part of the science curriculum for students to explore planets outside the classroom. After the picnic, students had fun in Gobuland, as they took part in different activities such as hiking, cycling, and Karting. They also played football and hide-and-seek. It was an enjoyable day well spent.


Introduction of Solar Eclipse Glasses
People all over the world are amazed and moved by solar eclipses and other amazing cosmic events in which the moon temporarily blocks out the sun. Seeing such rare sights is thrilling, but there is one important thing you should know: always protect yourself when looking straight into the sun. Solar eclipse glasses are an important piece of eclipse safety gear because they protect your eyes and give you a great view of this celestial event.
The Science Behind the Spectacle
Understanding why solar eclipse glasses are necessary requires taking a deep dive into eclipse science. An eclipse occurs when the moon aligns perfectly between our planet and the sun, casting its shadow across it. This event results in either partial or complete blocking of sunlight from reaching us and becoming visible again. The danger lies in the intense sunlight that can damage the eyes. Even during an eclipse, the sun’s rays can be harmful without adequate protection.
The Role of Solar Eclipse Glasses
Solar eclipse glasses provide eyewear designed specifically to shield users against the harmful rays of the sun, with solar filters to reduce brightness while blocking out UV, visible, and infrared radiation. Made from materials that meet international safety standards, these lenses enable wearers to observe an eclipse safely.
Choosing the Right Solar Eclipse Glasses
Not all sunglasses are created equal when it comes to solar eclipses. Choosing the right pair of solar eclipse glasses is crucial for a safe viewing experience. Look for glasses that meet the ISO 12312-2 international safety standard. This ensures that the glasses provide adequate eye protection during direct sun observation. Reputable vendors and science organizations often carry certified solar eclipse glasses.
Beware of Counterfeits
As the excitement builds around a solar eclipse, the market sees an influx of products claiming to offer safe viewing. Unfortunately, not all eyewear meets safety standards. Substandard or counterfeit glasses may expose your eyes to harmful radiation, leading to serious eye injuries. To avoid this, purchase solar eclipse glasses from reputable sources and verify their certification.
Sharing the Eclipse Experience Safely
Eclipse viewing is a communal activity that brings people together to witness the grandeur of the cosmos. To enhance the experience, consider organizing eclipse-watching events in your community. Provide reliable information about the importance of using solar eclipse glasses, and perhaps even collaborate with local astronomy enthusiasts or science organizations to ensure a safe and educational event.
Beyond Glasses: Other Safe Viewing Methods
While solar eclipse glasses are the most popular and accessible means of safe viewing, there are alternative methods. Projection techniques, such as using a pinhole projector or a telescope with solar filters, allow multiple people to view the eclipse simultaneously without the need for individual eyewear.
DIY Solar Eclipse Viewing: Crafting Your Own Pinhole Projector
While solar eclipse glasses are the go-to for safe viewing, there’s another intriguing option: the pinhole projector. Crafting your own projector is a simple and educational way to experience an eclipse without directly looking at the sun. Let’s delve into the DIY world of pinhole projectors and unlock a unique perspective on solar events.
The Magic of Pinhole Projection of Solar Eclipse Glasses
The concept behind a pinhole projector is based on the principle of light traveling in straight lines. By creating a small hole in a piece of paper or cardboard, sunlight passing through that hole projects an inverted image of the sun onto a surface. This low-tech solution allows you to witness the eclipse indirectly and is a fantastic project for families, schools, or anyone keen on a hands-on experience.
Crafting Your Pinhole Projector of Solar Eclipse Glasses
Creating a pinhole projector requires minimal materials. All you need for an eclipse projector is a large piece of cardboard or paper, aluminum foil, white paper, and a pin or needle. Cut a hole in the cardboard surface, cover it with aluminum foil, poke out one or more pinholes in it, and set your projector so that sunlight passes through its pinhole to project an image of an eclipsed sun onto white paper or flat surfaces.
Eclipse Photography: Capturing the Celestial Ballet
For those with a passion for photography, capturing the beauty of a solar eclipse is an enticing challenge. However, photographing the sun directly can damage your camera and your eyes. The solution? Solar filters for your camera lens. These specialized filters block harmful rays, allowing you to document the eclipse safely. Explore the world of eclipse photography and immortalize the celestial ballet with stunning visuals.
Choosing the Right Camera Filter
Selecting the appropriate solar filter for your camera is crucial. Similar to solar eclipse glasses, camera filters must meet the ISO 12312-2 safety standard. Ensure that the filter fits securely over your camera lens, providing full coverage. Experiment with different exposures and settings to achieve the perfect shot, but never compromise on safety.
The Global Eclipse Chaser Community
Eclipse chasing has become a global phenomenon, with enthusiasts traveling across continents to witness these cosmic events. Joining the eclipse chaser community opens up a world of shared experiences, valuable insights, and a chance to witness multiple eclipses throughout your lifetime. Connect with fellow eclipse chasers online, participate in forums, and share your own eclipse adventures.
Planning Your Eclipse Expedition
Successfully chasing a solar eclipse involves meticulous planning. Stay updated on upcoming eclipses, consider travel logistics, and familiarize yourself with the best viewing locations. Whether you’re a seasoned eclipse chaser or a first-timer, being part of this global community adds an extra layer of excitement to your celestial journey.
Safeguarding Your Vision for a Lifetime of Cosmic Wonders
As we marvel at the grandeur of solar eclipses, it’s crucial to prioritize eye safety. Whether you opt for the simplicity of solar eclipse glasses, the hands-on approach of a pinhole projector, or the artistic endeavor of eclipse photography, safeguarding your vision ensures a lifetime of enjoying the cosmic wonders our universe has to offer.

I was curious about how easy this would be to do, so the other day I took the leap and wrote a simple gravity simulator with the Earth and Sun. I googled for "planet table" and used the data from NASA's public planetary fact sheet. I used the average distance from the Sun and average orbital velocity to set initial conditions for the Earth. After applying the law of gravity, I got a nice circular orbit. The masses, distances, and velocities I used are all accurate, but the diameters are much larger than in the actual solar system. With the diameters at the proper scale, the sun would be a tiny spec and the earth would be invisible.
But once I simulated two bodies, it was too easy to resist adding more. So I took the data for Mercury, Venus, and Mars, and added them to the simulation. Each body is compared to every other body when computing accelerations due to gravity, but the Sun's mass is so much greater that it overshadows the planets' gravity no matter how close together they seem.
The orbits are still all circular however, while in real life they are elliptical. I might have been accurately simulating some solar system, but it was not ours. So I looked online again and found a NASA tool called HORIZONS, which can give accurate position and velocity information about celestial bodies in (x, y, z) Cartesian coordinates. I set the coordinate origin to be the Sun and chose data from today, August 28, 2016 to use as the initial conditions for my simulation. The result is a simulation of the actual elliptical orbits of the inner planets, with 1000-second granularity (I re-calculated accelerations due to gravity for every 1000 simulated seconds). I have included a date counter so that you can trace the Earth around the Sun and see that it does in fact cross the same point on the same date.
Then I added some cool comet-looking tails just because.
Here's the simulation with the outer planets instead of the inner planets. The granularity is 100,000 seconds and it is sped up 100x from the earlier simulations since the outer planets have such long orbital periods.


Welcome to LVVASTRO , Larry Van Vleet’s astronomical imaging website.
This website has been created to showcase my love for astronomical imaging. Like many in this hobby, I got my first telescope while still quite young and have maintained a healthy interest in astronomy ever since. I began experimenting with astro photography using a Celestron Schmidt camera around 1978 ( see first image here ) and from that small beginning, developed a fascination for the hobby that has now grown to include co-ownership of a fantastic remote observatory complex and a wide variety of equipment and processing tools. (see equipment list here)
Of course, the road forward has not been without it’s problems and frustrations. The emergence of robotic imaging was the real game changer for me, however. No more dragging a car full of equipment out to some remote darksky site 50 miles from home where I would freeze my behind off all night only to find out that the wind ruined 3/4 of my frames. No more trying to get up to go to work the next day on an hours worth of sleep or trying to explain to the girlfriend why I won’t be home all night because there is no moon and the sky is clear. Now I just login to my observatories from a home office, start up an imaging plan, and come back in the morning to see what I’ve got. Much better and a whole lot less painful!!! Of course, it is not really quite that simple… but almost.
Hopefully, you will enjoy what I have to offer here. One of my goals has been to show what can be accomplished using some of the fantastically capable amateur imaging hardware and software available today. If I can excite you about some of those amazing possibilities I will have accomplished a lot. I can’t wait to see what becomes available in the future.
Clear Sky and Happy Imaging to All…

Maybe you were laying in your bed one night, unable to sleep, and suddenly wondered, how many golf balls are on the moon?
It is a very odd question to ask yourself, but maybe there is a good reason for asking it.
In this article, we will tell you exactly how many golf balls are currently on the moon.
How Many Golf Balls Are On The Moon?
Currently, there are 2 golf balls located on the moon, left there by astronaut Alan Shepard in 1971 during the Apollo 14 mission. Astronaut Alan Shepard shot both balls with a 6-Iron club head and left the balls on the moon.
In fact, there are currently 2 white golf balls currently located on the surface of the moon, held their by the moon’s gravity field.
The 2 golf balls were not always on the moon, nor brought their by aliens. The golf balls were brought to the moon by former astronaut Alan Shepard.
In 1971, Alan Shepard reached the moon during the Apollo 14 mission, and decided to take out 2 golf balls.
He also took out a Wilson Staff Dyna-Power 6-Iron golf club head and attached it to a space lunar rock sampling tool.
Alan Shepard then wanted to hit the golf balls with the club head, but he could only use a single arm because of the stiffness of his spacesuit.
In the Nasa’s Official Transcript, we have access to reports of what Alan Shepard said while on the moon; here is an excerpt:
“Houston, while you’re looking that up, you might recognize what I have in my hand as the handle for the contingency sample return; it just so happens to have a genuine six iron on the bottom of it. In my left hand, I have a little white pellet that’s familiar to millions of Americans. I’ll drop it down. Unfortunately, the suit is so stiff, I can’t do this with two hands, but I’m going to try a little sand-trap shot here.”
Trying to still manage good golf shots, Alan Shepard shot both golf balls, sending them “flying” at unimpressive distances of 24 yards for the first ball and 40 yards for the second.
Why could Alan Shepard not shoot the moon golf balls further away?
First of all, using only one arm severely limited the power and ability to make the club follow the correct swing path during the 2 moon shots.
In addition, the moon’s gravity is much weaker than the Earth’s gravity, so it is a lot harder to accelerate the club head across space on the moon. With less club head speed, it is a lot harder to generate power, and thus, carry distance.
Today, the 2 golf balls shot by Alan Shepard are still on the moon, but the 6-Iron club head used was brought back to Earth, and now lies in the USGA Hall of Fame, located in New Jersey.
You can see the improvised golf club up above, made from the Wilson 6-Iron club head and the lunar rock sampling tool. It is now located in the USGA Hall of Fame in New Jersey.
If you are wondering why there is a sock on the image, it is because Alan Shepard used the sock to hold both the golf balls and the club head before using them.
Up above is an image of one of the golf ball currently on the moon. You can see the ball in the middle of the red circle. It is amazing that we can have images of the moon like this one, all thanks to technology.
There you go! After reading this article, you have discovered that there are in fact 2 golf balls currently located on the moon, despite how crazy it is to think about.
You learnt that Alan Shepard was the astronaut who left the 2 golf balls on the moon in 1971 during the Apollo 14 mission because he loved golf.
Can you believe there are golf balls on the moon? Let us know in the comments down below!

On the night of May 7, astronomers around the world were fortunate enough to watch the “Super Moon”-the moon looks particularly large and bright in the night sky.
This is because the moon, the satellite of the earth, has reached the closest distance to the earth, also known as perigee, and it is just opposite the earth and the sun.
Sara Russell, a planetary science researcher at the Natural History Museum in London, said that when the moon reaches the perigee, it looks 14% larger than the full moon on Earth.
Some people may find that the moon looks particularly large when it rises and falls. This is the so-called moon illusion. Russell said that the moon itself does not become larger and smaller, but there are trees or buildings as the sky. Compare with reference, and there is no other object to compare in the sky, so it looks smaller.
The super moon that appeared this month is also called the “flower moon” because it coincides with spring. It is the third super moon to appear this year and the last time this year.

How old is the universe? What do the atoms in our bodies, our very existence, tell us about the hist...
How old is the universe? What do the atoms in our bodies, our very existence, tell us about the history of the universe? How heavy is the vacuum? How do galaxies form? Michael Rowan-Robinson answers these questions and encapsulates all that modern astronomy has discovered about the universe around nine numbers. His motto is Montaigne's "What do I know?" And the reader emerges with a genuine feel for what we do really know about the universe and also what we do not. Only one of the nine numbers is known with real precision, while four of them are not known at all. Complicated ideas like the origin of the elements, the General Theory of Relativity, quantum theory, and the standard model of particle physics, ideas that constitute modern cosmology, are explained in a simple way. Speculative ideas like inflation, Theories of Everything, strings and superstrings, are also in this book, but they are treated with a refreshing skepticism. Although most of what we know has been learned during the twentieth century, Rowan-Robinson gives an historical perspective and honors the achievements of the Greeks, renaissance astronomers, and the age of Newton. He ends the book with an analysis of the future, predicting that with the advent of the MAP and PLANCK-Surveyor space missions, the Large Hadron Collider, and other planned experiments, all nine numbers will be accurately known by 2015. However, he stresses that many questions and mysteries will remain, and the book concludes with the idea that the origin of the Big Bang will remain a mystery in 2100 and perhaps even in the year 3000.


While Einstein is now a household name — and an iconic figure in science — it took the work of Sir Arthur Eddington to really bring him into the public consciousness. With one eclipse, he was able to prove Einstein’s theory — and spread proof of it to the masses. “On the 29th of May, 1919 the moon eclipsed the sun to allow a thin ray of light from the Hyades star cluster to fall into Sir Arthur Eddington’s telescopes,” the video explains. “Through his observations, he proved that light did not travel on straight lines around the sun, but rather on curved ones that deflected light. Eddington’s announcement made headlines, catapulting Einstein’s fame in the English-speaking world.”
Waiting out rain and difficult conditions, Eddington was determined to make his predicted observations a reality. You can see the video here:
Once a figure becomes cemented in history — and in science — it’s easy to forget the journey that they took to get there. But science is ever-evolving and new theories have to be tested and proven long before they enter textbooks. It’s amazing to think that one man’s observations helped shape the way we view Einstein today.


Sunspot numbers pulled up from 0 this week, but barely. Average daily sunspot numbers rose over nine points to 12.9. Geomagnetic conditions were quiet. Conditions have been quiet for so long that we may not appreciate this, as many of us wish for more solar activity and sunspots.
It wasn’t long ago when we had more sunspots, but the accompanying geomagnetic activity made conditions difficult. Check the Planetary A index in October 2002, April, June, September and December 2003, and into January 2004. For 2003, check http://www.sec.noaa.gov/ftpdir/indices/old_indices/2003_DGD.txt. For any other year, just change 2003 toward the end of the URL, and to check sunspot numbers change DGD to DSD at the end of the URL.
If you read ARRL Propagation Bulletins from back then, in addition to complaints about the higher geomagnetic activity, you’ll find stories of better VHF propagation during periods of geomagnetic disturbance. You can see old bulletins back through 1995 at, http://www.arrl.org/w1aw/prop/.
The Australian Ionospheric Prediction Service sent out a warning of increased geomagnetic activity centered on September 1 due to a wind stream from a solar coronal hole. They predict, August 31, will be quiet with increasing activity late in the day, unsettled to active conditions with possible minor storm on Saturday, September 1, and mostly unsettled conditions September 2.
Geophysical Institute Prague predicted earlier that August 31 would be quiet to unsettled, September 1 unsettled to active, unsettled conditions September 2-3, quiet September 4-5, and unsettled to active again on September 6.
Over the same period the US Air Force predicts a Planetary A index of 15, 25, 12, 12, 8, 5 and 15 for August 31 through September 6.
From the same prediction, it looks like September 8-17 may see a return of 0 sunspot days.

I started this post a full moon ago. I couldn't finish the post for a variety of reasons.
A lot has happened in the past month. Because of the global virus pandemic, my upcoming living situations were cancelled and I was offered a temporary house for which I am incredibly grateful. If you are on earth, you understand what an unusual experience we've been having. Everyone is dealing with a new reality and no one knows what life will look like when the virus has run its course or we've developed immunity or a vaccine has been developed, tested and distributed, or...
This is why it's taken me an entire moon cycle to get back to and finish this post.
Tonight is the Full Pink Moon in Libra.
I've lived by the moon for decades but in earnest since I spent a year on a remote strip of beach in South Carolina. I could walk to the shoreline at night, lay back and see the Milky Way and more stars than I could comprehend. One of the reasons I kept a keen eye on the moon was because I planned my daily life by the tides because when the tide was high, there was no beach for walking. I had a tide app on my phone that I would check every evening to structure my following day.
Why live by the moon? It's an elegant way of marking time on earth and other things.
Here are my top reasons for living by the moon:
Watching the moon is a way of marking time on earth. It's good to know that the moon is waxing or becoming full. This helps us keep in mind that things on earth are swelling to some crescendo. That the tide is rising. That my body will feel more swollen as we move closer to the full moon.
I don't think that the lunar experience is the same for men as it is for women. I'm sure that men are affected in some ways (if only through their relations with women!) but I can only speak to my experience as a woman. I swell as the moon waxes and slim as the moon wanes. When I menstruated, it was usually quite close to the full moon. Makes sense. Water courses through our physical tissues. The human body is 57-60% water. The tides swell with the waxing moon. It only follows that our human bodies do as well.
In looking back from one new or full moon to the previous, we can assess what's transpired in the cycle we've just passed through. I find that it's tremendously helpful to pause for reflection and to have a framework for review.
The cycles of the moon provide opportunities for completions and new beginnings. As humans being on earth, I think that we're designed to create. If you acknowledge that thoughts become things and you recognize that the average brain has anywhere from 25,000 to 50,000 thoughts a day, then it sort of follows that some of those thoughts are dedicated to creating something or other.
If you have any experience with creating just about anything (and I would be hard pressed to believe that you have no experience with this) then you know that some things are manifested and some things are not.
I, personally, find great solace in being able to hang onto the spiritual or cosmic or metaphysical hook of the moon cycle. If one idea does not work out or if I am wanting to bring one sort of experience to a close, I have an opportunity to close that off with the full moon.
With a new moon, I have the opportunity of intending a new beginning. Twelve new beginnings in one year! I like the idea. It's one of my favorite gifts that comes with living by the moon.
With the energetic help of the moon, I can close the door on past thoughts and experiences. I can set intentions for new experiences. How fabulous is that?
Paying attention to the lunar cycle grounds me to planet earth. Where would our moon be without earth? For that matter, where would any of us be without earth? Watching the moon helps to remind us that we are alive on planet earth. If we look to the moon and the sky and the stars, we have the opportunity to be aware that our feet are planted on the earth. That we are just a spec of consciousness on a planet with one satellite hurtling through space revolving around a sun. One sun of many, many, many suns.
It's good to be on earth. Earth is a gorgeous planet. You and I are on earth at this fascinating moment. What a literally wonderful experience. Especially figuring in our emotions! What a laugh.
Finally, the moon is beautiful, even in it's seeming absence. At the new moon, we can more clearly see the universe beyond. We can see the other planets in our system and the stars beyond. Or what were once stars.
Living by the moon enriches our human lives and reminds us that we are mere and magnificent on earth. Just for a little while.

On December 31st, at Petrovaradin Fortress in Novi Sad, Tesla Light Gallery will breathe life into the ambiance through a combination of light, sound, and interactive audio-visual art installations.
Tesla has left a legacy that will be showcased through artworks placed in Podgrađe, the tunnel, near the Clock Tower, the park on the Fortress, and in the Planetarium.
The central elements of this year's Tesla Light Gallery rely on the fact that Tesla had photographic memory, executed his inventions directly without drawings, and was an enthusiast of six great works of world literature. Faust (Goethe), Gorski vijenac (Njegoš), The Divine Comedy (Dante), Childe Harold (Byron), Eugene Onegin (Pushkin), and Hamlet (Shakespeare) served not only as inspiration but also as the foundation for creating new artistic pieces.
The artists making the realization of Tesla Light Gallery possible this year include Dr. Monika Bilbija Ponjavić, Miloš Martinov, Tijana Jevrić, Ivana Janošev, and Dutch artists Alex Prooper and Simone van Dam. Tesla Light Gallery will also involve students from the Academy of Arts and the Faculty of Technical Sciences in Novi Sad.
Specific segments of the Tesla Light Gallery will be realized in the Planetarium in collaboration with the Committee for the Development of the Space Program and the Astronomical Society Novi Sad.
Location and time:
Petrovaradin Fortress in Novi Sad – December 31st 2023


Click to see full answer. Thereof, why is radioactive dating important? Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. The universe is full of naturally occurring radioactive elements. Radioactive atoms are inherently unstable; over time, radioactive "parent atoms" decay into stable "daughter atoms. Additionally, does radioactive dating determine absolute age? Absolute dating methods determine how much time has passed since rocks formed by measuring the radioactive decay of isotopes or the effects of radiation on the crystal structure of minerals.
Radioactive iron in moon rocks collected by astronauts on NASA's Apollo missions suggests that a nearby supernova blasted Earth a few million years ago, according to a new study. This finding supports the idea that nearby stellar explosions may have influenced life on Earth, including the evolution of humans, the researchers said. Supernovas are powerful explosions from gigantic dying stars. These outbursts are visible all the way to the edge of the universe, and are bright enough to briefly outshine all of the other stars in their host galaxies. Previous research found that supernovas generate huge amounts of a mildly radioactive variety of iron known as iron, which these cataclysmic explosions spew out into space.
How do we know the age of the surfaces we see on planets and moons? If a world has a surface as opposed to being mostly gas and liquid , astronomers have developed some techniques for estimating how long ago that surface solidified. Note that the age of these surfaces is not necessarily the age of the planet as a whole. On geologically active objects including Earth , vast outpourings of molten rock or the erosive effects of water and ice, which we call planet weathering, have erased evidence of earlier epochs and present us with only a relatively young surface for investigation.


The speed of light is a universal constant, but, according to scientists at the University of Ottawa, not that constant. A team of researchers led by assistant professor Ebrahim Karimi has discovered that twisted light traveling through a vacuum moves slower than the speed set by Einstein’s theory of relativity, which has implications for quantum computing and communications…

|(a) General requirements. Students shall be awarded one credit for successful completion of this course. Suggested prerequisite: one unit of high school science. This course is recommended for students in Grade 11 or 12. (b) Introduction. (1) Astronomy. In Astronomy, students conduct laboratory and field investigations, use scientific methods, and make informed decisions using critical thinking and scientific problem solving. Students study the following topics: astronomy in civilization, patterns and objects in the sky, our place in space, the moon, reasons for the seasons, planets, the sun, stars, galaxies, cosmology, and space exploration. Students who successfully complete Astronomy will acquire knowledge within a conceptual framework, conduct observations of the sky, work collaboratively, and develop critical-thinking skills. (2) Nature of science. Science, as defined by the National Academy of Sciences, is the "use of evidence to construct testable explanations and predictions of natural phenomena, as well as the knowledge generated through this process." This vast body of changing and increasing knowledge is described by physical, mathematical, and conceptual models. Students should know that some questions are outside the realm of science because they deal with phenomena that are not scientifically testable. (3) Scientific inquiry. Scientific inquiry is the planned and deliberate investigation of the natural world. Scientific methods of investigation can be experimental, descriptive, or comparative. The method chosen should be appropriate to the question being asked. (4) Science and social ethics. Scientific decision making is a way of answering questions about the natural world. Students should be able to distinguish between scientific decision-making methods and ethical and social decisions that involve the application of scientific information. (5) Scientific systems. A system is a collection of cycles, structures, and processes that interact. All systems have basic properties that can be described in terms of space, time, energy, and matter. Change and constancy occur in systems as patterns and can be observed, measured, and modeled. These patterns help to make predictions that can be scientifically tested. Students should analyze a system in terms of its components and how these components relate to each other, to the whole, and to the external environment. (c) Knowledge and skills. (1) Scientific processes. The student, for at least 40% of instructional time, conducts laboratory and field investigations using safe, environmentally appropriate, and ethical practices. The student is expected to: (A) demonstrate safe practices during laboratory and field investigations; and (B) demonstrate an understanding of the use and conservation of resources and the proper disposal or recycling of materials. (2) Scientific processes. The student uses scientific methods during laboratory and field investigations. The student is expected to: (A) know the definition of science and understand that it has limitations, as specified in subsection (b)(2) of this section; (B) know that scientific hypotheses are tentative and testable statements that must be capable of being supported or not supported by observational evidence. Hypotheses of durable explanatory power which have been tested over a wide variety of conditions are incorporated into theories; (C) know that scientific theories are based on natural and physical phenomena and are capable of being tested by multiple independent researchers. Unlike hypotheses, scientific theories are well-established and highly-reliable explanations, but may be subject to change as new areas of science and new technologies are developed; (D) distinguish between scientific hypotheses and scientific theories; (E) plan and implement investigative procedures, including making observations, asking questions, formulating testable hypotheses, and selecting equipment and technology; (F) collect data and make measurements with accuracy and precision; (G) organize, analyze, evaluate, make inferences, and predict trends from data, including making new revised hypotheses when appropriate; (H) communicate valid conclusions in writing, oral presentations, and through collaborative projects; and (I) use astronomical technology such as telescopes, binoculars, sextants, computers, and software. (3) Scientific processes. The student uses critical thinking, scientific reasoning, and problem solving to make informed decisions within and outside the classroom. The student is expected to: (A) in all fields of science, analyze, evaluate, and critique scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing, including examining all sides of scientific evidence of those scientific explanations, so as to encourage critical thinking by the student; (B) communicate and apply scientific information extracted from various sources such as current events, news reports, published journal articles, and marketing materials; (C) draw inferences based on data related to promotional materials for products and services; (D) evaluate the impact of research on scientific thought, society, and the environment; and (E) describe the connection between astronomy and future careers. (4) Science concepts. The student recognizes the importance and uses of astronomy in civilization. The student is expected to: (A) research and describe the use of astronomy in ancient civilizations such as the Egyptians, Mayans, Aztecs, Europeans, and the native Americans; (B) research and describe the contributions of scientists to our changing understanding of astronomy, including Ptolemy, Copernicus, Tycho Brahe, Kepler, Galileo, Newton, Einstein, and Hubble, and the contribution of women astronomers, including Maria Mitchell and Henrietta Swan Leavitt; (C) describe and explain the historical origins of the perceived patterns of constellations and the role of constellations in ancient and modern navigation; and (D) explain the contributions of modern astronomy to today's society, including the identification of potential asteroid/comet impact hazards and the Sun's effects on communication, navigation, and high-tech devices. (5) Science concepts. The student develops a familiarity with the sky. The student is expected to: (A) observe and record the apparent movement of the Sun and Moon during the day; (B) observe and record the apparent movement of the Moon, planets, and stars in the nighttime sky; and (C) recognize and identify constellations such as Ursa Major, Ursa Minor, Orion, Cassiopeia, and constellations of the zodiac. (6) Science concepts. The student knows our place in space. The student is expected to: (A) compare and contrast the scale, size, and distance of the Sun, Earth, and Moon system through the use of data and modeling; (B) compare and contrast the scale, size, and distance of objects in the solar system such as the Sun and planets through the use of data and modeling; (C) examine the scale, size, and distance of the stars, Milky Way, and other galaxies through the use of data and modeling; (D) relate apparent versus absolute magnitude to the distances of celestial objects; and (E) demonstrate the use of units of measurement in astronomy, including Astronomical Units and light years.

That's so cool, thanks for posting pictures!
Over here it was from 1:30-5:00 (?) AM so I couldn't stay up and watch... plus, it was cloudy outside. I'm really glad I got to "see" it thanks to you! :)
That's awesome. My genius gal insisted on going to Griffith Observatory last night to "see" the eclipse.
I said hey genius you realize that it's raining and there is 0% chance of seeing anything but she insisted.
We heard a great lecture about solar and lunar eclipses, stuff I already knew because I am an astronomy (well, more cosmology) geek, but she was enthralled.
Sigh. the things I do.


Tonight's full moon also happens to be a super moon! This happens when the moon is as close to Earth as it can be - at the same time it happens to be full. This usually occurs once a year. The moon is now positioned only 356 955 kilometers from Earth.
So let's enjoy the soohing light from this lovely globe! My moon-music of choice today is one of the most beautiful, desperate sounding, classical pieces; Albinoni's Adagio.


Being away from the city one of the great things about Markdale is the starry sky at night.
The combination of the hills around Markdale and its distance from the light pollution in Sydney or Canberra also makes it a great place for observing stars, planets and other astronomical eye candy.
The only thing that would make it even better is a selection of some of the biggest portable telescopes around and a knowledgeable astronomical enthusiast to guide you.
And that’s exactly what you have with Lachlan MacDonald from OzSky annually at Markdale, complete with a whole range of telescopes up to 30″ in diameter.
Places are limited for the OzSky ‘Southern Spring’ Safari week and other events – find out more here about OzSky events.
If you are enthusiastic about astronomy OzSky at Markdale is a must. Check out the OzSky 2015 Markdale pictures.

Well Saturn, how's this for Aquarian? By which, I mean to say eccentric. Since Venus and Uranus stationed Retrograde last weekend, more Planets have been (apparently) traveling backwards through the Constellations of the Zodiac than forwards. Pluto, Neptune, Uranus, Chiron, Saturn, and Venus are all currently retrograde. Mercury, Mars, and Jupiter are currently direct, but none of them can be seen because they are too close to the Sun. This means every Planet we can see with eyes or Earth-Based telescopes is moving retrograde. This will hold until Saturn stations direct at 10:53pm PST tonight (8/1/15). What does it all mean? Good question.
Retrograde motion gives us an opportunity to go within for review and reset. Planets in the Underworld like Mercury, Mars, and Jupiter are being cleansed by the Fire of the Sun. Certainly, the coming Venus rebirth in Leo, the three 2015 Venus-Mars conjunctions and the three 2015 Venus-Jupiter Conjunctions are contributing to this quest.
The image that has been coming to me is a calling to compost our inner world tree into the soil from which our next will grow. It's much like the Tower card of the Tarot. Time to let the old Tower fall and to use its bricks to construct a new one. Another image that came in while I recorded this Hanuman / Kali Ma StarryTelling Podcast episode was that, with Saturn Retrograde in Scorpio, we are called to let the final feathers of the Phoenix burn so we can truly rise from the ashes. Perhaps the true rising begins with Saturn's station tonight and completes with Saturn's ingress into Sagittarius on September 17th, hours after Mercury next stations retrograde. Perhaps Saturn's entire transit through Sagittarius until December 19th, 2017 carries that cosmic calling. What will the coming Saturn Squares to Neptune, Jupiter, and the Lunar Nodes have to add to that quest?? And how about the Mutable Grand Cross formed by all of those players and the Gemini New Moon conjunct Venus next June? Intriguing! Time for some purification to prepare.
The Phoenix will rise! The new Tree will sprout! The new tower will be built! But first, can we let final feathers burn? Can we compost the old? Can we choose to dive from the crumbling Tower with hope as our cape rather than clutching our tired crown and falling in fear? The Fires of Will choose to follow the diver.
The Aquarius Moon shines brightly on this Revolution of Self. Sometimes we must destroy before we can create. What can you let burn today during Saturn's last hours of Scorpio retrograde?

As the first session in a 3 part series, I invite you to join us for an instructional series of presentations and field work focused on an introduction to night photography. At high level, the first session will provide a general background before going out into the field. Then, we’ll have a second session out in the field where we’ll shoot under the night sky up on Mount Evans. And then finally, we’ll have a follow-up instructional session where we’ll look at post-processing our images.
In the first session, I plan to cover a lot of ground…
I plan to cover a lot of ground, from the gear I use to the styles of lighting we have to choose from. I plan to share many of the tools I use to determine when is the best time to go out to shoot as well as a discussion on light pollution that helps to determine the best places to shoot as those have both become big keys to my success. This leads to a discussion of the different lighting styles that are available based on the conditions. We’ll also talk about the challenges to getting a good sharp focused image and how the limitations of sensors affect our strategy. I’ll share my approach to composite imaging that has worked well for me and some of the theory behind why astronomers like to stack multiple exposures. And then finally, we’ll review the settings we plan to use as a starting point when we go out night shooting on Mount Evans.
High level list of what you can expect from the first session:
• See the gear I typically use for night-photography.
• Hear my strategy for planning where to go and when to do it.
• Learn about the different night-time lighting conditions so you can choose locations that make the most of it.
• Discover tools that reveal where the light pollution is and what that means for choosing locations.
• Learn how to manually focus your lens in the dark.
• Step over to the astronomy side of photography and see why they like to stack multiple images.
• See for yourself why I like to blend multiple exposures.
It should be a great session with a ton of useful information. There’s no requirement for you to attend this session in order to join us for the night up on Mount Evans (or the post-processing session), but it is encouraged. I look forward to seeing you on August 20th.
