Less than two months after they inaugurated the world's largest telescope, University of Florida astronomers have used one of the world's most advanced telescopic instruments to gather images of the heavens. A team led by astronomy professor Stephen Eikenberry late last week captured the first images of the cosmos ever made with a UF-designed and built camera/spectrometer affixed to the Gemini South telescope in Chile. The handful of "first light" images include a yellow and blue orb-like...

The first of three images of ESO's GigaGalaxy Zoom project "” a new magnificent 800-million-pixel panorama of the entire sky as seen from ESO's observing sites in Chile "” has just been released online. The project allows stargazers to explore and experience the Universe as it is seen with the unaided eye from the darkest and best viewing locations in the world. This 360-degree panoramic image, covering the entire celestial sphere, reveals the cosmic landscape that surrounds our...

WASHINGTON, Aug. 5 /PRNewswire-USNewswire/ -- NASA's Spitzer Space Telescope is starting a second career and taking its first shots of the cosmos since warming up. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) The infrared telescope ran out of coolant May 15, 2009, more than five-and-one-half-years after launch. It has since warmed to a still-frosty 30 degrees Kelvin (about minus 406 degrees Fahrenheit). New images taken with two of Spitzer's infrared detector channels...

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...

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...

It sounds like the plot of a sci-fi movie: rogue black holes roaming our galaxy, threatening to swallow anything that gets too close. In fact, new calculations by Ryan O'Leary and Avi Loeb (Harvard-Smithsonian Center for Astrophysics) suggest that hundreds of massive black holes, left over from the galaxy-building days of the early universe, may wander the Milky Way. Good news, however: Earth is safe. The closest rogue black hole should reside thousands of light-years away. Astronomers are...

The "Cat's Eye" nebula, or NGC 6543, is a well-studied example of a "planetary nebula." Such objects are the glowing remnants of dust and gas expelled from moderate-sized stars during their last stages of life. Our own sun will generate such a nebula in about five billion years. NASA's Spitzer Space Telescope has studied many such planetary nebulae in infrared light, including a variety of more distant ones, which have helped scientists identify a population of carbon-bearing stars near our...

British astronomers say cosmic dust was partially created by the gradual death of carbon stars and not just from stars that exploded. The astronomers have been watching cosmic dust form around a dying star in a nearby galaxy, similar to the primitive galaxies that formed soon after the big bang, said a release from the Science and Technology Facilities Council, which funded the study. The newly observed dust formation was found around the carbon star MAG 29, located 280,000 light years away...

ITHACA, N.Y. "“ A Cornell-led team of astronomers has observed dust forming around a dying star in a nearby galaxy, giving a glimpse into the early universe and enlivening a debate about the origins of all cosmic dust. The findings are reported in the Jan. 16 issue of the journal Science (Vol. 323, No. 5912). Cornell research associate Greg Sloan led the study, which was based on observations with NASA's Spitzer Space Telescope. The researchers used Spitzer's Infrared Spectrograph,...

Milky Way Bigger Than Once Thought The Milky Way packs a big punch. In fact, scientists discovered that it is larger than Andromeda - not the little sister it was once thought to be. Scientists mapped the Milky Way in a more detailed, three-dimensional way and found that it's bulkier and spinning faster than astronomers once thought. The Milky Way is denser, with 50 percent more mass, and 15 percent larger in breadth. The research was presented Monday at the American Astronomical Society's...

Milky Way Galaxy -- The Milky Way (a translation of the Latin Via Lactea, in turn derived from the Greek Galaxia (gala, galactos means "milk")) is a hazy band of white light across the night sky formed by billions of stars in the disc of our galaxy. The Milky Way appears brightest in the direction of Sagittarius, where the galactic centre lies. Relative to the celestial equator, the Milky Way passes as far north as the constellation of Cassiopeia and as far south as the constellation of...
