The mind-blowing answer comes from a theory describing the birth of the universe in the first instant of time. 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. It's based on the discovery that energy is constantly welling up from the vacuum of space in the form of particles of opposite charge... matter and anti-matter.

Hubble Space Telescope Pictures with Gustav Holst's The Planets - 1080p HD - INCREDIBLE!
Eugene Ormandy Conducts the Philadelphia Orchestra performing Gustav Theodore Holst's "The Planets" movement Saturn, the Bringer of Old Age with the Hubble's top 100 high res pictures. I was overwhelmed looking at the pictures and the presence of a Higher Power is so evident at least to me so I wanted to put these two things together. It came out great I think. If you get a chance listen to his whole symphony you'll will love it. The suite has seven movements, each of them named after a planet and its corresponding Roman deity (see also Planets in astrology): 1.Mars, the Bringer of War 2.Venus, the Bringer of Peace 3.Mercury, the Winged Messenger 4.Jupiter, the Bringer of Jollity 5.Saturn, the Bringer of Old Age 6.Uranus, the Magician 7.Neptune, the Mystic The order of the movements corresponds to increasing distance of their eponymous planets from the Earth. Some commentators have suggested that this is intentional, with the anomaly of Mars preceding Venus being a device to make the first four movements match the form of a symphony.-- Gustav Holst (Composer), Ralph Vaughan Williams (Composer), Eugene Ormandy (Conductor), Philadelphia Orchestra (Orchestra)

Search for Another Earth Hubble directly observes planet orbiting Fomalhaut
Search for Another Earth The NASA/ESA Hubble Space Telescope has discovered an extrasolar planet, for the first time using direct visible-light imaging. The strange world is far-flung from its parent star, is surrounded by a colossal belt of gas and dust, and may even have rings more impressive than Saturn's. HUBBLE DIRECTLY OBSERVES A PLANET ORBITING ANOTHER STAR WASHINGTON — NASA's Hubble Space Telescope has taken the first visible-light snapshot of a planet circling another star. Estimated to be no more than three times Jupiter's mass, the planet, called Fomalhaut b, orbits the bright southern star Fomalhaut, located 25 light-years away in the constellation Piscis Australis, or the "Southern Fish." Fomalhaut has been a candidate for planet hunting ever since an excess of dust was discovered around the star in the early 1980s by NASA's Infrared Astronomy Satellite, IRAS. In 2004, the coronagraph in the High Resolution Camera on Hubble's Advanced Camera for Surveys produced the first-ever resolved visible-light image of the region around Fomalhaut. It clearly showed a ring of protoplanetary debris approximately 21.5 billion miles across and having a sharp inner edge. This large debris disk is similar to the Kuiper Belt, which encircles the solar system and contains a range of icy bodies from dust grains to objects the size of dwarf planets, such as Pluto. Hubble astronomer Paul Kalas, of the University of California at Berkeley, and team members proposed in 2005 that the ring was being gravitationally modified by a planet lying between the star and the ring's inner edge. Circumstantial evidence came from Hubble's confirmation that the ring is offset from the center of the star. The sharp inner edge of the ring is also consistent with the presence of a planet that gravitationally "shepherds" ring particles. Independent researchers have subsequently reached similar conclusions. Now, Hubble has actually photographed a point source of light lying 1.8 billion miles inside the ring's inner edge. The results are being reported in the November 14 issue of Science magazine. "Our Hubble observations were incredibly demanding. Fomalhaut b is 1 billion times fainter than the star. We began this program in 2001, and our persistence finally paid off," Kalas says. "Fomalhaut is the gift that keeps on giving. Following the unexpected discovery of its dust ring, we have now found an exoplanet at a location suggested by analysis of the dust ring's shape. The lesson for exoplanet hunters is 'follow the dust,'" said team member Mark Clampin of NASA's Goddard Space Flight Center in Greenbelt, Md. Observations taken 21 months apart by Hubble's Advanced Camera for Surveys' coronagraph show that the object is moving along a path around the star, and is therefore gravitationally bound to it. The planet is 10.7 billion miles from the star, or about 10 times the distance of the planet Saturn from our sun. The planet is brighter than expected for an object of three Jupiter masses. One possibility is that it has a Saturn-like ring of ice and dust reflecting starlight. The ring might eventually coalesce to form moons. The ring's estimated size is comparable to the region around Jupiter and its four largest orbiting satellites. Kalas and his team first used Hubble to photograph Fomalhaut in 2004, and made the unexpected discovery of its debris disk, which scatters Fomalhaut's starlight. At the time they noted a few bright sources in the image as planet candidates. A follow-up image in 2006 showed that one of the objects is moving through space with Fomalhaut but changed position relative to the ring since the 2004 exposure. The amount of displacement between the two exposures corresponds to an 872-year-long orbit as calculated from Kepler's laws of planetary motion. Future observations will attempt to see the planet in infrared light and will look for evidence of water vapor clouds in the atmosphere. This would yield clues to the evolution of a comparatively newborn 100-million-year-old planet. Astrometric measurements of the planet's orbit will provide enough precision to yield an accurate mass. NASA's James Webb Space Telescope, scheduled to launch in 2013 will be able to make coronagraphic observations of Fomalhaut in the near- and mid-infrared. Webb will be able to hunt for other planets in the system and probe the region interior to the dust ring for structures such as an inner asteroid belt.

Birth And Death Of The Universe
Hubble Space Telescope - 15 Years of Discovery (Episode 8): Birth And Death Of The Universe. In the 15 years that the NASA/ESA Hubble Space Telescope has orbited Earth, it has taken three-quarters of a million photographs of the cosmos. --- Please subscribe to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceMagazine • http://www.youtube.com/FFreeThinker --- In many ways Hubble is the most successful scientific project in the World, and this event is not likely to go unnoticed. The European Space Agency, ESA, has decided to celebrate this anniversary with the production of a Hubble 15th Anniversary movie called "Hubble - 15 Years Of Discovery". The movie covers all aspects of the Hubble Space Telescope project: a journey through the history, the trouble and the scientific successes of Hubble. This portrait of one of the biggest scientific projects of all time contains large amounts of previously unpublished footage in uncompromised quality. With the beautiful backdrop of Hubbles visual image treasures running as a red line through the movie, the light and dreaming style tells the most interesting stories about our fascinating Universe and about the change of vision that Hubble has brought us. --- The Hubble Space Telescope (HST), named after Edwin Powell Hubble (1889-1953) who was one of the great pioneers of modern astronomy, is a collaboration between ESA and NASA. It is a long-term, space-based observatory. The observations are carried out in visible, infrared and ultraviolet light. In many ways Hubble has revolutionised modern astronomy, not only by being an efficient tool for making new discoveries, but also by driving astronomical research in general. During 15 years of viewing the sky, Hubble has taken more than 700000 exposures of more than 22 000 celestial objects. The spacecraft itself has whirled around Earth nearly 88 000 times, travelling more than 4000 million kilometres. The orbiting observatory generates enough data every day - about 15 gigabytes - to fill more than three DVDs, and in total it has produced 23 terabytes of data, equal to the amount of text in 23 million novels. Over 3900 astronomers from all over the world have used the telescope, and compiled a long list of scientific achievements, published in more than 4000 papers, such as: - calculating the precise age of the Universe to be 13 700 million years old); - confirming the existence of a strange form of energy called dark energy; - detecting small proto-galaxies that emitted their light when the Universe was less than a 1000 million years old; - proving the existence of super-massive black holes; - seeing a comet hitting Jupiter; and - showing that the process of forming planetary systems is common throughout the galaxy. http://www.esa.int http://www.spacetelescope.org .

Hubblecast 24. Date- Source- http://www.spacetelescope.org/videos/archive/topic/hubblecast// 'There's no better place for a telescope than space itself. Above the Earth's atmosphere observations are no longer hampered by air turbulence, so telescopic images of distant stars and galaxies are razor-sharp. Unlike a ground-based telescope, an instrument in Earth orbit can operate twenty-four hours a day and reach every part of the sky. Observing from space also makes it possible to study types of radiation that are otherwise absorbed by the atmosphere. Little wonder that the Hubble Space Telescope has made so many contributions to astronomy. And Hubble is not alone — more than 100 space observatories have been launched since the 1960s.Watch this Hubblecast episode and find out more.'

The Most Distant Galaxies Ever Seen
In August, after the last repair mission on the Hubble Space Telescope, astronomers directed its newest camera towards the same area of sky where just five years ago, the first Hubble Ultra Deep field image was made and recorded a new one - this time in the near-infrared, a wavelength invisible to the human eye. Over the course of four days, the camera shutter was open for one hundred seventy three thousand seconds and astronomers collected photons that had left their galaxies over 13 billion years ago. Sensitive to slightly longer wavelengths than its predecessors, the newly installed camera known as Wide Field Camera three recorded objects that are likely the oldest galaxies ever identified, having formed only a few hundred million years after the Big Bang. Here are the results. [Music montage and interlude, couple minutes (music: Daemon portal)] Hubble's new camera looks closer towards the Big Bang than any of the earlier cameras on the Hubble Space Telescope because it collects light from near-infrared wavelengths. The expansion of the universe stretches light from hot young stars in these very distant galaxies out of the ultraviolet and visible regions of the spectrum and into near-infrared wavelengths, making them redder and invisible to the human eye. As we build instruments sensitive to longer and longer wavelengths, we are able to peer farther into the cosmos and each wavelength brings us views closer to the edge of the universe. When we focus our instruments outside the narrow band of light visible to our eyes, past the infrared and towards microwave and radio wavelengths, we open other windows that allow us to see deeper than ever before possible. The farthest we can ever hope to see reaches its limit in the microwave region of the spectrum. This is the wavelength of the radiation given off by the entire universe as it cools, which began just a few hundred thousand years after the big bang. This latest upgrade of the cameras on board the Hubble Space Telescope is setting the stage for a host of new discoveries. Because of the sensitivity to longer wavelengths, Hubble is showing us the most distant galaxies ever seen by human beings and we are able to capture glimpses of our universe like this.
