Spitzer Space Telescope scientists have successfully probed the center of the Milky Way and have come to a stunning conclusion: the center is full of chocolate nougat.

NASA's Spitzer Space Telescope has for the first time captured the light from two known planets orbiting stars other than our Sun. The findings mark the beginning of a new age of planetary science, in which "extrasolar" planets can be directly measured and compared.

Only 541 days into its mission, Spitzer has reached 10,000 science observations. The telescope's Infrared Spectrograph (IRS) captured the milestone observation of nearby spiral galaxy M83 on Feb. 16, 2005 at 9:12:27:02 UTC.

How do you hide something as big and bright as a galaxy? You smother it in cosmic dust. NASA's Spitzer Space Telescope saw through such dust to uncover a hidden population of monstrously bright galaxies approximately 11 billion light-years away.

The candles are lit, the champagne is on ice. All you need now are flowers and a ring. This Valentine's Day, NASA's Spitzer and Cassini spacecraft provide you with both, in two engaging new images.

Moons circle planets, and planets circle stars. Now, astronomers have learned that planets may also circle celestial bodies almost as small as planets.

NASA's Spitzer Space Telescope has uncovered a hatchery for massive stars.

When our solar system was young, its biggest babies ”Jupiter and Saturn” threw tantrums by the trillion. The huge planets hurled ice-covered rocky bodies from the inner solar system far past the orbit of Pluto.

Astronomers have numerous technical terms and numbering systems for describing the universe, but one type of mysterious object has yet to be classified. For now, these oddities are named for their strange appearance. They are called blobs.

The National Optical Astronomy Observatory (NOAO) has teamed with the Spitzer Science Center (SSC) to offer a dozen graduates from NOAO's advanced teacher professional development program a unique chance to make research-quality observations with NASA's Spitzer Space Telescope.

Astronomers say a dusty disk swirling around the nearby star Vega is bigger than earlier thought. It was probably caused by collisions of objects, perhaps as big as the planet Pluto, up to 2,000 kilometers (about 1,200 miles) in diameter.

On January 1, 2005, Spitzer was honored in the 116th Rose Parade. The JPL-Caltech float, called "A Family of Explorers," received the Crown City Innovation Trophy for Best Use of Imagination & Innovation to Advance the Art of Float Design.

When you watch the 116th Rose Parade on January 1, 2005, you'll see something spectacular: a gigantic Explorer figure which rises to 50 feet above the parade route and features nine spacecraft, including the Spitzer Space Telescope. This year, NASA's Jet Propulsion Laboratory and the California Institute of Technology will have a monumental float called "A Family of Explorers" in the annual Tournament of Roses Parade.

The Spitzer Science Center (SSC) with the collaboration of the National Optical Astronomy Observatory (NOAO) has designed a program for teacher and student research using observing time on the Spitzer Space Telescope. The participating teachers will attend a fall 2004 workshop to become familiar with the Spitzer Space Telescope archives and to receive training in infrared astronomy and observational techniques. The teachers will also attend a workshop offered by the SSC to learn about the observation planning process and telescope and instrument capabilities.

Two of NASA's Great Observatories, the Spitzer Space Telescope and the Hubble Space Telescope, have provided astronomers an unprecedented look at dusty planetary debris around stars the size of our Sun.

Two new results from NASA's Spitzer Space Telescope released today are helping astronomers better understand how stars form out of thick clouds of gas and dust, and how the molecules in those clouds ultimately become planets.

The astronomical community has received a new gift -- bundles of spruced up data from NASA's Spitzer Space Telescope. The data offer fresh infrared views of the universe, including dozens of images of galaxies and stars, and numerous chemical "fingerprints," or spectra, of planet-forming discs.

A "monster" lurking behind a blanket of cosmic dust is unveiled in this new Halloween image from NASA's Spitzer Space Telescope. Resembling a ghoul with two hollow eyes and a screaming mouth, this masked cloud of newborn stars was uncovered by Spitzer's heat-seeking infrared eyes.

Planets are built over a long period of massive collisions between rocky bodies as big as mountain ranges, astronomers announced today.

Just when astronomers thought they might have dug up the last of our galaxy's "fossils," they've discovered a new one in the galactic equivalent of our own backyard.

Four hundred years ago, sky watchers, including the famous astronomer Johannes Kepler, best known as the discoverer of the laws of planetary motion, were startled by the sudden appearance of a "new star" in the western sky, rivaling the brilliance of the nearby planets.

NASA's Spitzer Space Telescope has set its infrared sight on a major galactic collision and witnessed not death, but a teeming nest of life.

So just how good are Spitzer's infrared eyes? Well, the primary definition of that is what we call resolving power.

A new image from NASA's Spitzer Space Telescope shows the shimmering embers of a dying star, and in their midst a mysterious doughnut-shaped ring.

What would our Milky Way galaxy look like if we could travel outside it and snap a picture? It might look a lot like a new image by NASA's Spitzer Space Telescope of a spiral galaxy called NGC 7331 -- a virtual twin of our Milky Way.

Astronomers unveiled the deepest images from NASA's new Spitzer Space Telescope today and announced the detection of distant objects -- including several supermassive black holes -- that are nearly invisible in even the deepest images from telescopes operating at other wavelengths.

Peering into the "gut" of the galaxy Centaurus A, NASA's Spitzer Space Telescope has captured in unprecedented detail this massive galaxy's last big meal: a spiral galaxy twisted into a parallelogram-shaped structure of dust.
