NASA's Spitzer Space Telescope has imaged a wild creature of the dark -- a coiled galaxy with an eye-like object at its center. The galaxy, called NGC 1097, is located 50 million light-years away. It is spiral-shaped like our Milky Way, with long, spindly arms of stars. The "eye" at the center of the galaxy is actually a monstrous black hole surrounded by a ring of stars. In this color-coded infrared view from Spitzer, the area around the invisible black hole is blue and the ring of stars,...

Scientists have found evidence that another object has bombarded Jupiter, exactly 15 years after the first impacts by the comet Shoemaker-Levy 9. Following up on a tip by an amateur astronomer, Anthony Wesley of Australia, that a new dark "scar" had suddenly appeared on Jupiter, this morning between 3 and 9 a.m. PDT (6 a.m. and noon EDT) scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif., using NASA's Infrared Telescope Facility at the summit of Mauna Kea, Hawaii, gathered...

BOULDER, Colo., July 13 /PRNewswire-FirstCall/ -- Ball Aerospace & Technologies Corp. has completed environmental testing for NASA's Widefield Infrared Survey Explorer (WISE) and has begun post-environmental performance testing. WISE is working to a date of November 1, 2009 for launch from Vandenberg Air Force Base, Calif. (Photo: http://www.newscom.com/cgi-bin/prnh/20090713/LA45086) WISE environmental testing included thermal vacuum, electromagnetic compatibility, electromagnetic...

UC Riverside astronomer leads international team studying galaxy formation and evolution in early history of the universe An international team of researchers led by a UC Riverside astronomer has completed the largest ever survey designed to find very distant clusters of galaxies. Named the Spitzer Adaptation of the Red-sequence Cluster Survey, "SpARCS" detects galaxy clusters using deep ground-based optical observations from the CTIO 4m and CFHT 3.6m telescopes, combined with Spitzer Space...

Astronomers using the infrared capability of the U.S. space agency's Spitzer Space Telescope have found two newborn stars at the center of our galaxy. The heart of the Milky Way spiral galaxy is cluttered with stars, dust and gas, and at its center, a supermassive black hole, National Aeronautics and Space Administration scientists said. Conditions there are harsh, but astronomers have known stars can form in such chaotic space, however, until now nobody had been able to definitively locate...

NASA's Wide-field Infrared Survey Explorer, or WISE, has been assembled and is undergoing final preparations for a planned Nov. 1 launch from Vandenberg Air Force Base, Calif. The mission will survey the entire sky at infrared wavelengths, creating a cosmic clearinghouse of hundreds of millions of objects -- everything from the most luminous galaxies, to the nearest stars, to dark and potentially hazardous asteroids. The survey will be the most detailed to date in infrared light, with a...

Astronomers have at last uncovered newborn stars at the frenzied center of our Milky Way galaxy. The discovery was made using the infrared vision of NASA's Spitzer Space Telescope. The heart of our spiral galaxy is cluttered with stars, dust and gas, and at its very center, a supermassive black hole. Conditions there are harsh, with fierce stellar winds, powerful shock waves and other factors that make it difficult for stars to form. Astronomers have known that stars can form in this chaotic...

The U.S. space agency says its Spitzer Space Telescope is out of the coolant used to chill its infrared instruments and has entered a warm mode of operation. After more than five years of searching the cosmos, the National Aeronautics and Space Administration says Spitzer will warm up slightly, with only two of its infrared detector arrays operating. Spitzer ran out of its liquid helium coolant at 6:11 p.m. EDT Friday. Scientists and engineers will spend the next few weeks recalibrating the...

Scientists have long wondered how tiny silicate crystals, which need sizzling high temperatures to form, have found their way into frozen comets, born in the deep freeze of the solar system's outer edges. The crystals would have begun as non-crystallized silicate particles, part of the mix of gas and dust from which the solar system developed. A team of astronomers believes they have found a new explanation for both where and how these crystals may have been created, by using NASA's Spitzer...

The primary mission of NASA's Spitzer Space Telescope is about to end after more than five and a half years of probing the cosmos with its keen infrared eye. Within about a week of May 12, the telescope is expected to run out of the liquid helium needed to chill some of its instruments to operating temperatures. The end of the coolant will begin a new era for Spitzer. The telescope will start its "warm" mission with two channels of one instrument still working at full capacity. Some of the...
