![]() ![]() It was previously believed that the Andromeda Galaxy, and others like it, were “spiral nebulas” within the Milky Way.Īlthough the HST is named after Hubble, its history begins with another man: Lyman Spitzer. Wilson Observatory in Los Angeles-then the largest telescope in the world-to discover that the Andromeda is its own galaxy. In the 1920s, Edwin Hubble used the 100-inch telescope at Mt. Hubble, the American astronomer who confirmed that the universe is expanding, which provides the foundation for the Big Bang theory. The Hubble Space Telescope is named after Edwin P. UA astronomer Mark Sykes was on the team that captures the images.Ģ011: UA Lunar and Planetary Lab Professor Adam Showman contributed to Hubble’s one millionth scientific observation, an eclipsing extrasolar planet and host star. The images of Vesta and Ceres showed two of the most massive asteroids in the asteroid belt, a region between Mars and Jupiter and helped astronomers plan for the Dawn spacecraft’s tour of these asteroids. UA astronomer for Steward Observatory Glenn Schneider was on the team that captured these images.Ģ006: A team led by then UA astronomer Doug Clowe and including Steward Observatory astronomer Dennis Zaritsky found direct proof of dark matter using Hubble Space Telescope.Ģ007: Hubble took images of asteroids that helped astronomers prepare for a spacecraft visit. The team used the Hubble telescope to observe 18 galaxies out to 65 million light-years.įirst view of a dust ring around a star taken by Hubble space telescope for University of Arizona researchġ999: The Hubble Space Telescope gave astronomers their first views of a dust ring around a star and a dark gap dividing an immense dust disk around another star. The team found that a galaxy appears to be moving 160 thousand miles per hour faster for every 3.3 light-years away from Earth. This perspective is unusual because the Earth is slightly above Saturn’s rings and the Sun is below them, so normally we see the rings fully illuminated by the Sun.ġ999: Hubble completed an eight-year effort to measure the expanding universe, co-led by Robert Kennicutt, then UA professor of astronomy. Using infrared filters, Hubble captured detailed features of three layers of the planet’s atmosphere.ġ996: Through research done by then UA senior staff scientist Steve Larson and others, Hubble captured a rare view of Saturn’s rings, seen just after the sun had set below the ring plane. The images revealed that, in fact, there was at least some solid surface on Titan.ġ996: A team that included Erich Karkoschka, UA Lunar and Planetary Lab senior staff scientist, captured images of Uranus’s atmosphere, observing clear and hazy layers created by a mixture of gases. At the time, scientists suspected that Titan’s surface was covered with a global ethane-methane ocean. Below are just some of the discoveries that UA astronomers have made using Hubble.ġ994: A team of astronomers led by Peter Smith, professor emeritus at the UA, took the world’s first images of Saturn’s moon, Titan. Since then, nearly 20 University of Arizona researchers have been named Hubble fellows. Each year since 1990, NASA has funded the research efforts of a select group of astronomers through its prestigious Hubble Fellowship. The University of Arizona has contributed to innumerable studies in space sciences, and its researchers have been using NASA’s Hubble Space Telescope to do so for decades. University of Arizona Discoveries on Hubble Hubble has observed locations more than 13.4 billion light years away, meaning it has seen light that existed in the universe 13.4 billion years ago.Īstronomers using Hubble data have published more than 13,000 journal articles, making it one of the most productive scientific instruments ever built. Hubble orbits the Earth at a cruising speed of 17,000 miles per hour, and takes 15 minutes to rotate 90 degrees. It requires much less power than one might think, averaging 2,100 watts of power usage. ![]() Hubble gathers energy from the sun using two 25-foot solar panels. That’s just under two adult male African bush elephants. Hubble Space Telescope is about the size of a large school bus. Here, we offer information on Hubble, its history, and how UA astronomers have used it to create new astronomical knowledge. Researchers from the UA and across the globe have used Hubble to peer into distant galaxies, and to better understand the history and the future of our expanding universe. Since the early 1990s, NASA’s Hubble Space Telescope has been a favorite instrument of University of Arizona astronomers. ![]()
