06.10.09 - Astronomers have at last uncovered newborn stars at the frenzied center of our Milky Way galaxy.
05.15.09 - After more than five-and-a-half years of probing the cool cosmos, Spitzer has run out of the coolant that kept its infrared instruments chilled.
05.13.09 - Scientists have long wondered how tiny silicate crystals, which need sizzling high temperatures to form, have found their way into frozen comets.
05.06.09 - 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.
05.04.09 - NASA's Spitzer Space Telescope is about to use its last drop of the coolant that has chilled it for the past five-and-a-half years.
04.30.09 - This image from NASA's Spitzer Space Telescope shows the spiral galaxy NGC 2841, located about 46 million light-years from Earth in the constellation Ursa Major.
04.07.09 - Life on Earth is thought to have arisen from a hot soup of chemicals. Does this same soup exist on planets around other stars?

03.16.09 - A new image from NASA's Spitzer Space Telescope offers a rare view of an imminent collision between the cores of two merging galaxies, each powered by a black hole with millions of times the mass of the sun.
01.05.09 - Astronomers have turned to an unexpected place to study the evolution of planets -- dead stars.
12.10.08 - It's a tie! The new record-holder for dimmest known star-like object in the universe goes to twin "failed" stars, each of which shines feebly with only one millionth the light of our sun.
12.09.08 - NASA's Hubble Space Telescope has discovered carbon dioxide in the atmosphere of a planet orbiting another star.
