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?
04.02.09 - A collection of NASA missions will be involved in a live event Friday, April 3, that will allow the public to get an inside look at how these missions are run.
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.
12.08.08 - A new image from NASA's Spitzer Space Telescope shows a turbulent star-forming region, where rivers of gas and stellar winds are eroding thickets of dusty material.
11.11.08 - Shock waves around dusty, young stars might be creating the raw materials for planets, according to new observations from NASA's Spitzer Space Telescope.
10.27.08 - New observations from NASA's Spitzer Space Telescope indicate that the nearest planetary system to our own has two asteroid belts.
10.08.08 - Different wavelengths of light swirl together like watercolors in a new, ethereal portrait of a bright, star-forming region.

07.15.08 - A contender for the title of brightest star in our Milky Way galaxy has been unearthed in the dusty metropolis of the galaxy's center. Nicknamed the "Peony nebula star," it blazes with the light of an estimated 3.2 million suns.
07.10.08 - Astronomers have uncovered an extreme stellar machine -- a galaxy in the very remote universe pumping out stars at a surprising rate of up to 4,000 per year.
