On Earth, thieves steal everything from diamonds to art to bags full of money. In space, gas -- fuel for making stars -- is a commodity worth the price of theft.
Dusty infrared galaxies are cosmic "nurseries" for some of the universe's hottest young stars -- and new research from NASA's Spitzer Space Telescope shows that when the universe was approximately six billion years old, these galaxies packed into the densest "zip codes" in space. Astronomers hope that this latest finding will give them insights into why the modern universe looks the way it does.
The hit song that proclaimed, "All we are is dust in the wind," may have some cosmic truth to it. New findings from NASA's Spitzer Space Telescope suggest that space dust -- the same stuff that makes up living creatures and planets -- was manufactured in large quantities in the winds of black holes that populated our early universe.
An Earth-like planet is likely forming 424 light-years away in a star system called HD 113766, say astronomers using NASA's Spitzer Space Telescope.
The National Women's Hall of Fame has selected Dr. Judith Pipher, a Spitzer Space Telescope astronomer, to join its ranks. Pipher is one of nine women to be inducted during a weekend of ceremonies October 6-7, 2007.
View the world through heat-sensitive infrared eyes at SkInfrared, a free art exhibit presented by NASA's Spitzer Space Telescope science center at the One Colorado Courtyard in Old Pasadena, Calif. -- from October 10 to 31, 2007. This exhibit is held in conjunction with Pasadena's Skin/Art & Ideas 2007 festival.
On Earth, neon signs point to motel vacancies and nearby eateries. Now for the first time, astronomers have spotted neon gas in disks around stars -- and they're hoping the glowing gas will point the way to new discoveries about how planets rise from the materials that swirl around young stars.
NASA's Hubble and Spitzer Space Telescopes have joined forces to discover nine of the smallest, faintest, most compact galaxies ever observed in the distant Universe. Blazing with the brilliance of millions of stars, each of the newly discovered galaxies is a hundred to a thousand times smaller than our Milky Way Galaxy.
NASA's Spitzer Space Telescope has detected enough water vapor to fill the oceans on Earth five times inside the collapsing nest of a forming star system. Astronomers say the water vapor is pouring down from the system's natal cloud and smacking into a dusty disk where planets are thought to form.
A newly expanded image of the Helix nebula lends a festive touch to the fourth anniversary of the launch of NASA's Spitzer Space Telescope. This spectacular object, a dying star unraveling into space, is a favorite of amateur and professional astronomers alike. Spitzer has mapped the expansive outer structure of the six-light-year-wide nebula, and probed the inner region around the central dead star to reveal what appears to be a planetary system that survived the star's chaotic death throes.
Transport to a universe of ever-changing sights, sounds, and spaces at the Los Angeles County Arboretum's second annual "Terrabyte" event on August 26, 2007 from 5 to 10 PM PDT.
New evidence from NASA's Spitzer Space Telescope shows that supermassive black holes at the centers of elliptical galaxies keep the galactic "thermostat" so high gas cannot cool, stunting the birth of new stars.

A spectacular new image from NASA's Spitzer Space Telescope uncovers a small group of young stellar "siblings" in the southern portion of the Serpens cloud, located approximately 848 light-years away from Earth. Scientists suspect that this discovery will lead them to more clues about how these cosmic families -- which contain hundreds of gravitationally bound stars -- form and interact.
Four galaxies are slamming into each other and kicking up billions of stars in one of the largest cosmic smash-ups ever observed.
How many stars does it take to "raise" a planet? In our own solar system, it took only one -- our Sun. However, new research from NASA's Spitzer Space Telescope shows that planets might sometimes form in systems with as many as four stars.
A scorching-hot gas planet beyond our solar system is steaming up with water vapor, according to new observations from NASA's Spitzer Space Telescope.
Astronomers suspect the early Earth was a very harsh place. Temperatures were extreme, and the planet was constantly bombarded by cosmic debris. Many scientists believe that life's starting materials, or building blocks, must have been very resilient to have survived this tumultuous environment.
Astronomers now have a new "eye" for determining the distance to certain mysterious bodies in and around our Milky Way galaxy. By taking advantage of the unique position of NASA's Spitzer's Space Telescope millions of miles from Earth, and a depth-perceiving trick called parallax, they were able to pin down the most probable location of one such object. The findings will ultimately help astronomers better understand the different components of our galaxy.
An astronomer at the Spitzer Science Center has discovered three giant stellar streams arcing high over the Milky Way. Remnants of cannibalized galaxies and star clusters, the streams are between 13,000 and 130,000 light-years distant from Earth and extend over much of the northern sky. The new results are being presented by Carl Grillmair at this week's meeting of the American Astronomical Society in Honolulu, Hawaii.
Large galaxy clusters are the universe's metropolises, and for years many astronomers have focused their attention on the crowded "downtowns." However, a new map of some of the largest ancient galactic cities shows that much of the "action" is happening in the cosmic suburbs.
In just a short amount of time, NASA's Spitzer Space Telescope has bagged thousands of previously unknown dwarf galaxies in a giant cluster of galaxies.
A new image from NASA's Spitzer Space Telescope shows infant stars "hatching" in the head of Orion, the famous hunter constellation visible from northern hemispheres during winter nights. Astronomers suspect that shockwaves from a 3-million-year-old explosion of a massive star may have initiated this newfound birth.
Researchers using NASA's Spitzer Space Telescope have learned what the weather is like on two distant, exotic worlds. One team of astronomers used the infrared telescope to map temperature variations over the surface of a giant gas planet, HD 189733b, revealing it likely is whipped by roaring winds. Another team determined that the gas planet HD 149026b is the hottest yet discovered.
Rainbow-colored jets in the cosmic cloud BHR 71 point to a celestial smash occurring 600 light-years away from Earth -- and NASA's Spitzer Space Telescope provides an exclusive peek at the "jet-setting" stars inside.
Astronomers may be one step closer to understanding how the ingredients of life are processed in space, thanks to NASA's Spitzer Space Telescope.
Astronomers have laid down the cosmic equivalent of yellow "caution" tape around super hot stars, marking the zones where cooler stars are in danger of having their developing planets blasted away.
The Seven Sisters, also known as the Pleiades, seem to float on a bed of feathers in a new infrared image from NASA's Spitzer Space Telescope. Clouds of dust sweep around the stars, swaddling them in a cushiony veil.
A team of NASA scientists led by a member of the Spitzer Science Center believe they have found a way to predict the color of plants on planets in other solar systems.
Using a quartet of space observatories, University of Maryland astronomers may have cracked a 45-year mystery surrounding two ghostly spiral arms in the galaxy M106.
