WASHINGTON, June 30, 2011 /PRNewswire-USNewswire/ -- Galaxies once thought of as voracious tigers are more like grazing cows, according to a new study using NASA's Spitzer Space Telescope. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Astronomers have discovered that galaxies in the distant universe continuously ingested their star-making fuel over long periods of time. This goes against previous theories that galaxies devoured their fuel in quick bursts after run-ins...

Astronomers working with data from several observatories, including ESA's XMM-Newton, have discovered the most distant, mature galaxy cluster yet. The cluster is seen as it was when the Universe was only about a quarter of its current age. In contrast to other structures observed in the young Universe, this object is already in its prime, as is evident from its diffuse X-ray emission and evolved population of galaxies. This shows that fully-grown galaxy clusters were already in place this...

Astronomers are a bit like archeologists as they dig back through space and time searching for remnants of the early universe. In a recent deep excavation, courtesy of NASA's Spitzer Space Telescope, astronomers unearthed what may be the most distant, primitive cluster of galaxies ever found. In a twist, however, this apparent ancestor to today's "big cities" of grouped galaxies looks shockingly modern. Called CLG J02182-05102, the ancient cluster is dominated by old, red and massive...

The discovery of a previously unresolved population of galaxies in the GOODS fields and the first measurements of properties of galaxies in the almost unexplored far-infrared domain are among the first exciting scientific results achieved by Herschel's PACS and SPIRE instruments. These findings confirm the extraordinary capabilities of ESA's new infrared space observatory to investigate the formation and evolution of galaxies. These are some of the many discoveries presented this week at the...

NASA's best-recognized, longest-lived, and most prolific space observatory zooms past a threshold of 20 years of operation this month. On April 24, 1990, the space shuttle and crew of STS-31 were launched to deploy the Hubble Space Telescope into a low Earth orbit. What followed was one of the most remarkable sagas of the space age. Hubble's unprecedented capabilities made it one of the most powerful science instruments ever conceived by humans, and certainly the one most embraced by the...

Hubble shows that the beautiful spirals galaxies of the modern Universe were the ugly ducklings of six billion years ago. If confirmed, the finding highlights the importance to many galaxies of collisions and mergers in the recent past. It also provides clues for the unique status of our own galaxy, the Milky Way. Using data from the NASA/ESA Hubble Space Telescope, astronomers have created a census of galaxy types and shapes from a time before Earth and the Sun existed, up to the present...

More than 12 billion years of cosmic history are shown in this unprecedented, panoramic, full-color view of thousands of galaxies in various stages of assembly. This image, taken by NASA's Hubble Space Telescope, was made from mosaics taken in September and October 2009 with the newly installed Wide Field Camera 3 (WFC3) and in 2004 with the Advanced Camera for Surveys (ACS). The view covers a portion of the southern field of a large galaxy census called the Great Observatories Origins Deep...

Mission's decade of success peering into the final frontier XMM-Newton, the most powerful X-ray observatory ever built and launched into space, marks its 10th anniversary on December 10th. XMM-Newton's observations have revolutionized the way we view the hottest and most extreme regions of the Universe. Scientists from the UK who have played a pivotal role in the success of the orbiting observatory, which is the size of a small bus, will be marking the occasion at a special event in Madrid...

First results from the GOODS NICMOS survey, the largest Hubble Space Telescope program ever led from outside of the United States, reveal how the most massive galaxies in the early Universe assembled to form the most massive objects in the Universe today. Dr Chris Conselice from the University of Nottingham will present the results at the European Week of Astronomy and Space Science at the University of Hertfordshire on Wednesday 22nd April. The observations are part of the Great...

The U.S. space agency is planning a special exhibit to celebrate Galileo's 445th birthday and 2009's designation as the International Year of Astronomy. In conjunction with Galileo's birthday next Sunday, the National Aeronautics and Space Administration is releasing images from its Great Observatories -- the Hubble and Spitzer space telescopes and the Chandra X-ray Observatory -- to more than 100 U.S. planetariums, museums, nature centers and schools. The selected sites will unveil a large...
