Sunrise
Sunrise or sun up is the instant at which the upper edge of the Sun appears over the horizon in the morning. The term can also refer to the entire process of the Sun crossing the horizon and its accompanying atmospheric effects. Although the Sun appears to "rise" from the horizon, it is actually the "Earth's" motion that causes the Sun to appear. The illusion of a moving Sun results from Earth observers being in a rotating reference frame; this apparent motion is so convincing that most cultures had mythologies and religions built around the geocentric model, which prevailed until astronomer Nicolaus Copernicus first formulated the heliocentric model in the 16th century.
Extraterrestrial skies
In astronomy, an extraterrestrial sky is a view of outer space from the surface of a world other than Earth. The only extraterrestrial sky that has been directly observed and photographed by astronauts is that of the Moon. The skies of Titan, Mars, and Venus have been observed by space probes designed to land on the surface and transmit images back to Earth. Characteristics of extraterrestrial skies appear to vary substantially due to a number of factors. An extraterrestrial atmosphere, if present, has a large bearing on visible characteristics. The atmosphere's density and chemical composition can contribute to differences in colour, opacity (including haze) and the presence of clouds.
Sundial
A sundial is a device that tells the time of day when there is sunlight by the apparent position of the Sun in the sky. In the narrowest sense of the word, it consists of a flat plate (the "dial") and a "gnomon", which casts a shadow onto the dial. As the Sun appears to move across the sky, the shadow aligns with different "hour-lines", which are marked on the dial to indicate the time of day. The "style" is the time-telling edge of the gnomon, though a single point or "nodus" may be used. The gnomon casts a broad shadow; the shadow of the style shows the time. The gnomon may be a rod, wire, or elaborately decorated metal casting.
Solstice
A solstice is an event occurring when the Sun appears to reach its most northerly or southerly excursion relative to the celestial equator on the celestial sphere. Two solstices occur annually, on about 21 June and 21 December. The seasons of the year are directly connected to both the solstices and the equinoxes. The term "solstice" can also be used in a broader sense, as the day when this occurs. The day of the solstice in either hemisphere has either the most sunlight of the year (summer solstice) or the least sunlight of the year (winter solstice) for any place other than the Equator. Alternative terms, with no ambiguity as to which hemisphere is the context, are June solstice and December solstice, referring to the months of year in which they take place.
Sunset
Sunset or sundown is the daily disappearance of the Sun below the horizon as a result of Earth's rotation. The Sun will set exactly due west at the equator on the spring and fall equinoxes, each of which occurs only once a year. The time of sunset is defined in astronomy as the moment when the trailing edge of the Sun's disk disappears below the horizon. Near to the horizon, atmospheric refraction causes the ray path of light from the Sun to be distorted to such an extent that geometrically the Sun's disk is already about one diameter below the horizon when a sunset is observed. Sunset is distinct from twilight, which has three phases, the first being "civil" twilight, which begins once the Sun has disappeared below the horizon, and continues until it descends to 6 degrees below the horizon; the second phase is "nautical" twilight, between 6 and 12 degrees below the horizon; and the third is "astronomical" twilight, which is the period when the Sun is between 12 and 18 degrees below the horizon.
Sun
The Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. It is by far the most important source of energy for life on Earth. Its diameter is about 1.39 million kilometers, i.e. 109 times that of Earth, and its mass is about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System. About three quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron.
List of Warriors characters
The "Warriors" novel series is written by Erin Hunter. Due to the large number of characters present in the novel series, this list is divided by Clan, e.g., all characters in ThunderClan are listed together. Each cat has a prefix. Eg: Dawn, Violet etc. As a young kit they will have -kit at the end of their name. Eg: Dawnkit Violetkit. When they are an apprentice -paw will be at the end of their name. Eg: Dawnpaw Violetpaw. When that cat is a warrior or medicine cat they will have a suffix. Eg: -fur -pelt -cloud -flame -wing -song etc. Eg: Dawnsong Violetflame. That is if they are in one of the clans like ThunderClan, RiverClan, WindClan, ShadowClan, Skyclan.

Well if you're not up that early you could always catch a sunset when the dun dips below the horizon as a result of the Earth's rotation?

Archaeoastronomy
Archaeoastronomy (also spelled archeoastronomy) is the study of how people in the past "have understood the phenomena in the sky, how they used these phenomena and what role the sky played in their cultures". Clive Ruggles argues it is misleading to consider archaeoastronomy to be the study of ancient astronomy, as modern astronomy is a scientific discipline, while archaeoastronomy considers symbolically rich cultural interpretations of phenomena in the sky by other cultures. It is often twinned with "ethnoastronomy", the anthropological study of skywatching in contemporary societies. Archaeoastronomy is also closely associated with historical astronomy, the use of historical records of heavenly events to answer astronomical problems and the history of astronomy, which uses written records to evaluate past astronomical practice.
East Link Extension (Sound Transit)
The East Link Extension is a future light rail line that will become part of Sound Transit's Link light rail system in the Seattle metropolitan area of the U.S. state of Washington. It will serve 10 stations from Downtown Seattle to the Eastside suburbs of Mercer Island, Bellevue, and Redmond, running from west to east. East Link is scheduled to open in 2023 as part of the Blue Line, which will continue into the Downtown Seattle Transit Tunnel and share stations with the Red Line. A extension to Downtown Redmond with two additional stations is scheduled to open in 2024. The East Link project, projected to cost $3.7 billion to construct, was approved by voters in the 2008 Sound Transit 2 ballot measure.

Mercury (planet)
Mercury is the smallest and innermost planet in the Solar System. Its orbital period around the Sun of 88 days is the shortest of all the planets in the Solar System. It is named after the Roman deity Mercury, the messenger to the gods. Like Venus, Mercury orbits the Sun within Earth's orbit as an "inferior planet", and never exceeds 28° away from the Sun. When viewed from Earth, this proximity to the Sun means the planet can only be seen near the western or eastern horizon during the early evening or early morning. At this time it may appear as a bright star-like object, but is often far more difficult to observe than Venus.
Orbit of the Moon
The Moon orbits Earth in the prograde direction and completes one revolution relative to the stars in about 27.323 days (a sidereal month) and one revolution relative to the Sun in about 29.530 days (a synodic month). Earth and the Moon orbit about their barycentre (common center of mass), which lies about from Earth's center (about of the radius of Earth). On average, the distance to the Moon is about from Earth's center, which corresponds to about 60 Earth radii. With a mean orbital velocity of , the Moon covers a distance approximately its diameter, or about half a degree on the celestial sphere, each hour.
History of the petroleum industry in Canada (natural gas)
Natural gas has been used almost as long as crude oil in Canada, but its commercial development was not as rapid. This is because of special properties of this energy commodity: it is a gas, and it frequently contains impurities. The technical challenges involved to first process and then pipe it to market are therefore considerable. Furthermore, the costs of pipeline building make the whole enterprise capital intensive, requiring both money and engineering expertise, and large enough markets to make the business profitable. Until it became commercially viable, natural gas was often a nuisance.

See? And what's funny about the sun is it appears to rise and set but it's actually the Earth's motion that causes the sun to appear and disappear.

List of Madagascar (franchise) characters
This is a list of characters that have appeared in the "Madagascar" films, the television series "The Penguins of Madagascar", and the Netflix series "All Hail King Julien". Tom McGrath explained in an interview that the intention of "Madagascar" was not to take a political stance on whether "zoos are bad and the wild is better, or that the wild is bad," but to show "the most extreme 'fish out of water' story that [they] could do". McGrath stated "the basic irony to the story is that, you think animals do belong in the wild, but if they're so accustomed to civility, they wouldn't know where food even came from," and the animals were meant to "love the zoo and to love where they are because they've got" "right off Fifth Avenue".

Planet Nine
Planet Nine is a hypothetical planet in the outer Solar System. Its gravitational influence could explain the abnormal orbits of a group of trans-Neptunian objects (TNOs) found mostly beyond the Kuiper belt. Speculation about the alignment of TNOs began with a 2014 letter to the journal "Nature". Astronomers Chad Trujillo and Scott S. Sheppard noted the possible existence of a trans-Neptunian planet after comparing the similar orbits of trans-Neptunian objects Sedna and . In early 2016, researchers Konstantin Batygin and Michael E. Brown described how the similar orbits of six TNOs could be explained by Planet Nine and proposed a possible orbit for the planet.
Future of Earth
The biological and geological future of Earth can be extrapolated based upon the estimated effects of several long-term influences. These include the chemistry at Earth's surface, the rate of cooling of the planet's interior, the gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity. An uncertain factor in this extrapolation is the ongoing influence of technology introduced by humans, such as climate engineering, which could cause significant changes to the planet. The current Holocene extinction is being caused by technology and the effects may last for up to five million years.
List of minor DC Comics characters
American comic book publishing company DC Comics has introduced many characters throughout its history, including numerous minor characters. These characters range from supporting characters, heroes and villains that appear infrequently, to characters that only take part in a single story. Airstryke is a supervillain in the DC Universe. Within the context of the stories, William Kavanagh was given the ability to transform into a pterosaur/man hybrid by a weapons company named Meta/Tech and he took the name Airstryke. Count Viper took advantage of these new abilities and used Airstryke to distract Hawkman while Viper tried to take command of the Justice League and thus the world.

Astrobiology
Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe: extraterrestrial life and life on Earth. Astrobiology addresses the question of whether life exists beyond Earth, and how humans can detect it if it does. The term exobiology is similar but more specific—it covers the search for life beyond Earth, and the effects of extraterrestrial environments on living things. Astrobiology makes use of physics, chemistry, astronomy, biology, molecular biology, ecology, planetary science, geography, and geology to investigate the possibility of life on other worlds and help recognize biospheres that might be different from that on Earth.
Asteroid mining
Asteroid mining is the exploitation of raw materials from asteroids and other minor planets, including near-Earth objects. Minerals can be mined from an asteroid or spent comet then used in space for construction materials or taken back to Earth. These include gold, iridium, silver, osmium, palladium, platinum, rhenium, rhodium, ruthenium and tungsten for transport back to Earth; iron, cobalt, manganese, molybdenum, nickel, aluminium, and titanium for construction. Due to the high launch and transportation costs of spaceflight, inaccurate identification of asteroids suitable for mining, and in-situ ore extraction challenges, terrestrial mining remains the only means of raw mineral acquisition today.
Carl Sagan
Carl Edward Sagan (; November 9, 1934 – December 20, 1996) was an American astronomer, cosmologist, astrophysicist, astrobiologist, author, science popularizer, and science communicator in astronomy and other natural sciences. He is best known for his work as a science popularizer and communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space: the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them.
Outer space
Outer space, or just space, is the expanse that exists between celestial bodies, including Earth. Outer space is not completely empty—it is a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays. The baseline temperature, as set by the background radiation from the Big Bang, is 2.7 kelvins (K) (−270.45 °C; −454.81 °F). The plasma between galaxies accounts for about half of the baryonic (ordinary) matter in the universe; it has a number density of less than one hydrogen atom per cubic metre and a temperature of millions of kelvins; local concentrations of this plasma have condensed into stars and galaxies.
Panspermia
Panspermia () is the hypothesis that life exists throughout the Universe, distributed by space dust, meteoroids, asteroids, comets, planetoids, and also by spacecraft in the form of unintended contamination by microorganisms. Panspermia is a hypothesis proposing that microscopic life forms that can survive the effects of space, such as extremophiles, become trapped in debris ejected into space after collisions between planets and small Solar System bodies that harbor life. Some organisms may travel dormant for an extended amount of time before colliding randomly with other planets or intermingling with protoplanetary disks.
Abiogenesis
Abiogenesis (British English: , ), biopoiesis, or informally the origin of life, is the natural process by which life arises from non-living matter, such as simple organic compounds. On Earth, the transition from non-living to living entities was not a single event but a gradual process of increasing complexity. Abiogenesis is studied through a combination of paleontology, chemistry, and extrapolation from the characteristics of modern organisms, and aims to determine how pre-life chemical reactions gave rise to life on Earth. The study of abiogenesis can be geophysical, chemical, or biological, with more recent approaches attempting a synthesis of all three, as life arose under conditions that are strikingly different from those on Earth today.
