The galaxy NGC 4395 is shown here in infrared light, captured by NASA's Spitzer Space Telescope. This dwarf galaxy is relatively small in comparison with our Milky Way galaxy, which is nearly 1,000 times more massive.
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.
This image of the galaxy cluster Abell 2744 was obtained with NASA's Hubble Space Telescope. The zoomed image shows the region around the galaxy Abell2744_Y1, one of the most distant galaxy candidates known.
This long-exposure image from NASA's Hubble Space Telescope of massive galaxy cluster Abell 2744 is the deepest ever made of any cluster of galaxies. Shown in the foreground is Abell 2744, located in the constellation Sculptor.
The view is a composite of images taken in visible and near-infrared light by NASA's Hubble Space Telescope. Researchers have circled four unusually red objects that appear as they existed just 500 million years after the big bang.
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.
The center of the Milky Way galaxy imaged by NASA's Spitzer Space Telescope is displayed on a quarter-of-a-billion-pixel, high-definition 23-foot-wide (7-meter) LCD science visualization screen at NASA's Ames Research Center.
Partially Cloudy Skies on Kepler-7b (Artist Concept)
Kepler-7b (right), which is 1.5 times the radius of Jupiter (left), is the first exoplanet to have its clouds mapped. The cloud map was produced using data from NASA's Kepler and Spitzer space telescopes.
This artist's concept portrays a free-floating brown dwarf, or failed star. A new study using data from NASA's Spitzer Space Telescope shows that several of these objects are warmer than previously thought.
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.
