This mosaic reveals a panorama of the Milky Way from NASA's Spitzer Space Telescope. This picture covers only about three percent of the sky, but includes more than half of the galaxy's stars and the majority of its star formation activity.
The closest supernova of its kind to be observed in the last few decades, M82 or the 'Cigar galaxy,' has sparked a global observing campaign involving legions of instruments on the ground and in space, including NASA's Spitzer Space Telescope.
The collection of red dots seen here show one of several very distant galaxy clusters discovered by combining ground-based optical data from the NOAO's Kitt Peak National Observatory with infrared data from NASA's Spitzer Space Telescope.
Combined observations from NASA's Spitzer Space Telescope and the newly completed Atacama Large Millimetre/submillimeter Array (ALMA) in Chile have revealed the throes of stellar birth in the well-studied object known as HH 46/47.
There are nearly 200 galaxies within the marked circles in this image from NASA's Spitzer Space Telescope. These are part of the Perseus-Pisces supercluster of galaxies located 250 million light-years away.
This infrared image from NASA's Spitzer Space Telescope shows a striking example of what is called a hierarchical bubble structure, in which one giant bubble, carved into the dust of space by massive stars, has triggered the formation of smaller bubbles.
How many rings do you see in this new image of galaxy Messier 94, also known as NGC 4736? At first glance one might see a number of them, astronomers believe there is just one. This image was captured in infrared light by NASA's Spitzer Space Telescope.
Taken Under the 'Wing' of the Small Magellanic Cloud
The tip of the 'wing' of the Small Magellanic Cloud galaxy is dazzling in this new view from NASA's Great Observatories. The SMC, is a small galaxy about 200,000 light-years way that orbits our own Milky Way spiral galaxy.
The giant star Zeta Ophiuchi, a young, large and hot star located around 370 light-years away, is having a 'shocking' effect on the surrounding dust clouds in this infrared image from NASA's Spitzer Space Telescope.
The image on the left shows a portion of our sky, called the Boötes field, in infrared light, while the image on the right shows a mysterious, background infrared glow captured by NASA's Spitzer Space Telescope in the same region of sky.
This image from NASA's Spitzer and GALEX shows the Helix nebula, a dying star throwing a cosmic tantrum. In death, the star's dusty outer layers are unraveling into space, glowing from the intense UV radiation being pumped out by the hot stellar core.
This infrared image, from NASA's Spitzer Space Telescope, of M100 is a classic example of a grand design spiral galaxy, with prominent and well-defined spiral arms winding from the hot center, out to the cooler edges of the galaxy.
The galaxy Messier 100, or M100, shows its swirling spiral in this infrared image from NASA's Spitzer Space Telescope. The arcing spiral arms of dust and gas that harbor star forming regions glow vividly when seen in the infrared.
Astronomers have uncovered patterns of light that appear to be from the first stars and galaxies that formed in the universe. The light patterns were hidden within a strip of sky observed by NASA's Spitzer Space Telescope.
