This artist's rendering gives us a glimpse into a cosmic nursery as a star is born from the dark, swirling dust and gas of this cloud.
This image shows two young brown dwarfs, objects that fall somewhere between planets and stars in terms of their temperature and mass.
In this spectacular image, observations using infrared light and X-ray light see through the obscuring dust and reveal the intense activity near the galactic core.
In celebration of the International Year of Astronomy 2009, NASA's Great Observatories -- the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory -- have produced a matched trio of images of the central region of our Milky Way galaxy.
NASA's Spitzer Space Telescope captured this infrared image of a giant halo of very fine dust around the young star HR 8799, located 129 light-years away in the constellation Pegasus.
The basic chemistry for life has been detected in a second hot gas planet, HD 209458b, depicted in this artist's concept.
This picture shows a slice of Saturn's largest ring, as seen in infrared light by NASA's Spitzer Space Telescope.
NASA's Spitzer Space Telescope has spotted a nearly invisible ring around Saturn -- the largest of the giant planet's many rings.
This diagram illustrates the extent of the largest ring around Saturn, discovered by NASA's Spitzer Space Telescope.
This diagram highlights a slice of Saturn's largest ring.
This video showcases the Saturnian system, beginning with the planet itself and panning out to its newest addition.
This artist's conception shows a lump of material in a swirling, planet-forming disk.
This composite image, combining data from NASA's Chandra X-ray Observatory and Spitzer Space Telescope shows the star-forming cloud Cepheus B, located in our Milky Way galaxy about 2,400 light years from Earth.
This artist's concept shows a celestial body about the size of our moon slamming at great speed into a body the size of Mercury.
NASA's Spitzer Space Telescope has imaged a wild creature of the dark -- a coiled galaxy with an eye-like object at its center.
These data from NASA's Spitzer Space Telescope reveal a newborn star at the center of our Milky Way.
This infrared image from NASA's Spitzer Space Telescope shows three baby stars in the bustling center of our Milky Way galaxy.
This artist's concept illustrates how silicate crystals like those found in comets can be created by an outburst from a growing star.
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.
NASA's Spitzer Space Telescope detected a prebiotic, or potentially life-forming, molecule called hydrogen cyanide (HCN) in the planet-forming disks around yellow stars like our sun, but not in the disks around cooler, reddish stars.
