    -This video illustrates the scaled size of our universe from quarks to the entirety of the observable universe. Each circle used in the video represents a scale factor of 10; meaning each larger circle is zoomed out 10x more than its predecessor. ( i.e. after 1 circle you are now looking at 10x larger horizon, after 2 circles 100x, 3 would be 1000x, and so forth. This also applies to the speed, ignoring relativistic effects, at which the observer (you) would be traveling.) *EDIT: Please note that the zoom out from 2:26 - 2:34 is a simplistic model of the *hypothetical* mutliverse intended to aid conceptualization of the idea, but is currently not definitively known to science and is most certainly NOT part of the observable universe.

    From ESOCast: An international team of astronomers using ESO's Very Large Telescope has measured the distance to the most remote galaxy so far. This is the first time that astronomers have been able to confirm that they are observing a galaxy as it was in the era of reionization — when the first generation of brilliant stars was making the young Universe transparent and ending the cosmic Dark Ages. We are going to find out how a team of astronomers used ESO's Very Large Telescope, the VLT, to confirm that a galaxy that had previously been spotted in images from the NASA/ESA Hubble Space Telescope is in fact the most distant object that is ever been identified in the Universe. Studying these first galaxies is extremely difficult; they are very faint and small and by the time their dim l...

The universe has long captivated us with its immense scales of distance and time. How far does it stretch? Where does it end, and what lies beyond its star fields and streams of galaxies extending as far as telescopes can see? These questions are beginning to yield to a series of extraordinary new lines of investigation and technologies that are letting us to peer into the most distant realms of the cosmos. But also at the behavior of matter and energy on the smallest of scales. Remarkably, our growing understanding of this kingdom of the ultra-tiny, inside the nuclei of atoms, permits us to glimpse the largest vistas of space and time. In ancient times, most observers saw the stars as a sphere surrounding the earth, often the home of deities. The Greeks were the first to see celestial events as phenomena, subject to human investigation rather than the fickle whims of the Gods. One sky-watcher, for example, suggested that meteors are made of materials found on Earth... and might have even come from the Earth. Those early astronomers built the foundations of modern science. But they would be shocked to see the discoveries made by their counterparts today. The stars and planets that once harbored the gods are now seen as infinitesimal parts of a vast scaffolding of matter and energy extending far out into space. Just how far began to emerge in the 1920s. Working at the huge new 100-inch Hooker Telescope on California's Mt. Wilson, astronomer Edwin Hubble, along with his assistant named Milt Humason, analyzed the light of fuzzy patches of sky... known then as nebulae. They showed that these were actually distant galaxies far beyond our own. Hubble and Humason discovered that most of them are moving away from us. The farther out they looked, the faster they were receding. This fact, now known as Hubble's law, suggests that there must have been a time when the matter in all these galaxies was together in one place. That time, when our universe sprung forth, has come to be called the Big Bang. How large the cosmos has gotten since then depends on how long its been growing and its expansion rate. Recent precision measurements gathered by the Hubble space telescope and other instruments have brought a consensus... That the universe dates back 13.7 billion years. Its radius, then, is the distance a beam of light would have traveled in that time ... 13.7 billion light years. That works out to about 1.3 quadrillion kilometers. In fact, it's even bigger.... Much bigger. How it got so large, so fast, was until recently a deep mystery. That the universe could expand had been predicted back in 1917 by Albert Einstein, except that Einstein himself didn't believe it until he saw Hubble and Humason's evidence. Einstein's general theory of relativity suggested that galaxies could be moving apart because space itself is expanding. So when a photon gets blasted out from a distant star, it moves through a cosmic landscape that is getting larger and larger, increasing the distance it must travel to reach us. In 1995, the orbiting telescope named for Edwin Hubble began to take the measure of the universe... by looking for the most distant galaxies it could see. Taking the expansion of the universe into account, the space telescope found galaxies that are now almost 46 billion light years away from us in each direction... and almost 92 billion light years from each other. And that would be the whole universe... according to a straightforward model of the big bang. But remarkably, that might be a mere speck within the universe as a whole, according to a dramatic new theory that describes the origins of the cosmos.

Check out more awesome BuzzFeedBlue videos! http://bit.ly/YTbuzzfeedblue1 “There are more stars in our Universe than there are grains of sand on all the beaches on Earth.” There are 100 to 400 billion stars in the Milky Way and more than 100 billion galaxies in the Universe – maybe as many as 500 billion. If you multiply stars by galaxies, at the low end, you get 10 billion billion stars, or 10 sextillion stars in the Universe – a 1 followed by 22 zeros. At the high end, it’s 200 sextillion. These are mind bogglingly huge numbers. How do they compare to the number of grains of sand on the collective beaches of an entire planet? This type of sand measures about a half millimeter across. You could put 20 grains of sand packed in side-by-side to make a centimeter. 8000 grains in one cubic centimeter. If you took 10 sextillion grains of sand, put them into a ball, it would have a radius of 10.6 kilometers. And for the high end of our estimate, 200 sextillion, it would be 72 kilometers across. If we had a sphere bigger than the Earth, it would be an easy answer, but no such luck. This might be close. So, is there that much sand on all the beaches, everywhere, on this planet? You’d need to estimate the average volume of a sandy beach and the average amount of the world’s coastlines which are beaches. The estimates and calculations made by Dr. Jason Marshall, aka, the Math Dude are that, there about 700 trillion cubic meters of beach of Earth, and that works out to around 5 sextillion grains of sand.

-This video illustrates the scaled size of our universe from quarks to the entirety of the observable universe. Each circle used in the video represents a scale factor of 10; meaning each larger circle is zoomed out 10x more than its predecessor. ( i.e. after 1 circle you are now looking at 10x larger horizon, after 2 circles 100x, 3 would be 1000x, and so forth. This also applies to the speed, ignoring relativistic effects, at which the observer (you) would be traveling.) *EDIT: Please note that the zoom out from 2:26 - 2:34 is a simplistic model of the *hypothetical* mutliverse intended to aid conceptualization of the idea, but is currently not definitively known to science and is most certainly NOT part of the observable universe. I left some comments explaining why I kept it in the video for those who still aren't satisfied with this explanation. Thanks and enjoy! ***IMPORTANT INFORMATION UPDATE***: In October of 2016, NASA has conducted another deep field survey with Hubble and found that the already unfathomably large observable universe actually has.... about 10x more galaxies than we originally thought, putting the new estimated total at around 2 trillion. That means that there are more galaxies in our viewable universe than there are stars in our own galaxy, by a large margin. And remember, this is all just the parts of the universe we can see. Much of it is obscured behind a cosmic horizon where the light cannot reach us. Truly astounding.

It’s amazing to imagine what it could be like at the very edge of the universe, what it looks like, what is out there. If it were possible to see this part of space, we would see the beginning of the universe as it began. But once something slips past the event horizon, it becomes lost to our sight, no longer giving off light signals. Spacetime is a fascinating subject. One that needs to be explored to fully understand just how big the known universe is. So let’s take a journey to the outside of the known universe and answer: What Happens at The Edge of the Universe.

From ESOCast: An international team of astronomers using ESO's Very Large Telescope has measured the distance to the most remote galaxy so far. This is the first time that astronomers have been able to confirm that they are observing a galaxy as it was in the era of reionization — when the first generation of brilliant stars was making the young Universe transparent and ending the cosmic Dark Ages. We are going to find out how a team of astronomers used ESO's Very Large Telescope, the VLT, to confirm that a galaxy that had previously been spotted in images from the NASA/ESA Hubble Space Telescope is in fact the most distant object that is ever been identified in the Universe. Studying these first galaxies is extremely difficult; they are very faint and small and by the time their dim light gets to Earth it falls mostly in the infrared part of the spectrum because it has been stretched by the expansion of the Universe. To make matters worse, at this very early time, less than a billion years after the Big Bang, the Universe was not completely transparent. It was filled with hydrogen which acted kind of like a fog and absorbed the ultraviolet radiation from the young galaxies. So, holding the record for having measured the redshift of the most distant object in the Universe is not just a trophy to hang on the wall, it does have important astrophysical implications. This is the first time that we've managed to obtain spectroscopic observations of a galaxy from the era of reionization, in other words from the time when the Universe was still clearing out the hydrogen fog. Despite the difficulties of finding these early galaxies, the new Wide Field Camera 3 on the NASA/ESA Hubble Space Telescope discovered several very good candidate objects earlier in 2010. They were thought to be galaxies shining in the early Universe at redshifts greater than eight, but confirming the distances to such faint and remote objects is an enormous challenge and can only reliably be done using spectroscopy from very large ground-based telescopes. The team was excited to find that if you combine the huge light collecting power of the VLT, with the sensitivity of its infrared spectroscopic instrument, SINFONI, and if you then use a very long exposure time you just might be able to detect the faint glow from one of these very remote objects and then go on to measure its distance. A 16 hour exposure with the VLT and SINFONI of the galaxy UDFy-38135539 did indeed show the very faint glow from hydrogen at a redshift of 8.6, which means that this light left the galaxy when the Universe was only about 600 million years old. This is the most distant galaxy ever reliably confirmed. One of the puzzling things about this discovery is that the ultraviolet radiation emitted by the galaxy does not actually seems to be strong enough to be able to clear out the hydrogen fog around the galaxy. So one possible explanation is that there must be other galaxies, probably fainter and less massive neighbours, that helped ionize the hydrogen in the region of space around the galaxy, thus making it transparent. Without this additional help the brilliant light from the main galaxy would have been trapped in the surrounding hydrogen fog and it could not have even started its 13 billion-year journey towards Earth. Studying the era of reionization and the formation of the first galaxies is really pushing the capability of current telescopes and instruments to the limit. But, this will be exactly the type of science that ESO's European Extremely Large Telescope will excel at. Once operational, this will be the largest optical and infrared telescope in the world.

With a size of 2600 solar radii, it is the largest known star and also one of the most luminous known. It is located about 1.5 kiloparsecs (4.6×1016 km) or about 4,900 light years away from Earth. Unlike most stars, which occur in either binary or multiple star systems, VY CMa is a single star. It is categorized as a semiregular variable and has an estimated period of 6,275,081 days, or just under 17,200 years. Antares is a red supergiant star in the Milky Way galaxy and the sixteenth brightest star in the nighttime sky (sometimes listed as fifteenth brightest, if the two brighter components of the Capella quadruple star system are counted as one star). Along with Aldebaran, Spica, and Regulus it is one of the four brightest stars near the ecliptic. Antares is a variable star, whose apparent magnitude varies from +0.9 to +1.8. The Pistol Star is a blue hypergiant and is one of the most luminous known stars in the Milky Way Galaxy. It is one of many massive young stars in the Quintuplet cluster in the Galactic Center region. The star owes its name to the shape of the Pistol Nebula, which it illuminates. It is located approximately 25,000 light years from Earth in the direction of Sagittarius. It would be visible to the naked eye as a fourth magnitude star, if it were not for the interstellar dust that completely hides it from view in visible light. Rigel (β Ori / β Orionis / Beta Orionis) is the brightest star in the constellation Orion and the sixth brightest star in the sky, with visual magnitude 0.18. Although it has the Bayer designation "beta", it is almost always brighter than Alpha Orionis (Betelgeuse). Aldebaran (α Tau, α Tauri, Alpha Tauri) is an orange giant star located about 65 light years away in the zodiac constellation of Taurus. With an average apparent magnitude of 0.87 it is the brightest star in the constellation and is one of the brightest stars in the nighttime sky. The name Aldebaran is Arabic (الدبران al-dabarān) and translates literally as "the follower", presumably because this bright star appears to follow the Pleiades, or Seven Sisters star cluster in the night sky. This star is also called the Bull's Eye because of its striking orange color and its location in the bull's head shaped asterism. NASA's Pioneer 10 spacecraft, which flew by Jupiter in 1973, is currently traveling in the direction and will reach it in about two million years. ArcturusBoo / α Boötis / Alpha Boötis) is the brightest star in the constellation Boötes. With a visual magnitude of0.05, it is also the third brightest star in the night sky, after Sirius and Canopus. It is, however, fainter than the combined light of the two main components of Alpha Centauri, which are too close together for the eye to resolve as separate sources of light, making Arcturus appear to be the fourth brightest. It is the second brightest star visible from northern latitudes and the brightest star in the northern celestial hemisphere. The star is in the Local Interstellar Cloud. Pollux (β Gem / β Geminorum / Beta Geminorum) is an orange giant star approximately 34 light-years from the Earth in the constellation of Gemini (the Twins). Pollux is the brightest star in the constellation, brighter than Castor (Alpha Geminorum). As of 2006, Pollux was confirmed to have an extrasolar planet orbiting it. Sirius is the brightest star in the night sky. With a visual apparent magnitude of −1.46, it is almost twice as bright as Canopus, the next brightest star. The name Sirius is derived from the Ancient Greek Σείριος. The star has the Bayer designation α Canis Majoris (α CMa, or Alpha Canis Majoris). What the naked eye perceives as a single star is actually a binary star system, consisting of a white main sequence star of spectral type A1V, termed Sirius A, and a faint white dwarf companion of spectral type DA2, termed Sirius B. The Sun is the star at the center of the Solar System. The Sun has a diameter of about 1,392,000 kilometres (865,000 mi) (about 109 Earths), and by itself accounts for about 99.86% of the Solar System's mass; the remainder consists of the planets (including Earth), asteroids, meteoroids, comets, and dust in orbit. About three-fourths of the Sun's mass consists of hydrogen, while most of the rest is helium. http://en.wikipedia.org/wiki/Largest_stars --- CREDITS Animations: morn1415, NASA, ESO, Hubblecast Editing: http://www.youtube.com/Best0fScience .

http://gplus.to/TonyDarnell http://facebook.com/SpaceFan This video is the first of a series that will highlight the science behind The James Webb Space Telescope. JWST will have the capability of showing us a part of the universe we've never seen before: a time when the first stars were born, lived their lives, and died. Here, the concepts of recombination, reionization, the first stars and black holes are presented. JWST will give us our first glimpse into this time in our universal history. This video was produced over the summer as part of the STScI Summer Student Program. I had the privilege of working with Aimei Kutt and +Tiffany Davis to make a video highlighting some of the amazing science The James Webb Space Telescope will allow us to accomplish. Aimei produced the wonderful animation sequences you see and Tiffany edited the video and created the graphics and titles. They both worked on the music (and learned how time consuming that part is). It is my pleasure to offer this to you, I hope you enjoy watching it as much as we enjoyed making it.
