This image of galaxy cluster Abell 2744, also called Pandora's Cluster, was taken by NASA's Spitzer Space Telescope. The gravity of this galaxy cluster is strong enough that it acts as a lens to magnify images of more distant background galaxies.
These nebulae seen by NASA's Spitzer Space Telescope, display two regions of star formation that are hidden behind a haze of dust when viewed in visible light, known officially y their catalog numbers, IRAS 19340+2016 and IRAS19343+2026.
This artist's concept shows NASA's Spitzer Space Telescope. Spitzer begins its 'Beyond' mission phase on Oct. 1, 2016. Spitzer is depicted in the orientation it assumes to establish communications with ground stations.
This illustration shows one possible scenario for the hot, rocky exoplanet called 55 Cancri e, which is nearly two times as wide as Earth. New data from NASA's Spitzer Space Telescope show that the planet has extreme temperature swings.
Astronomers have made the most detailed study yet of an extremely massive young galaxy cluster using three of NASA's Great Observatories. This rare galaxy cluster, located 10 billion light-years from Earth, is almost as massive as 500 trillion suns.
This image shows an artist's impression of the 10 hot Jupiter exoplanets studied using the Hubble and Spitzer space telescopes. (Top L, Bottom R -- WASP-12b, WASP-6b, WASP-31b, WASP-39b, HD 189733b, HAT-P-12b, WASP-17b, WASP-19b, HAT-P-1b, HD 209458b)
Cool Star Marked by Long-Lived Storm (Artist's Concept)
This illustration shows a cool star, called W1906+40, marked by a raging storm near one of its poles. The storm is thought to be similar to the Great Red Spot on Jupiter. Scientists discovered it using NASA's Kepler and Spitzer space telescopes.
The galaxy cluster called MOO J1142+1527 can be seen here as it existed when light left it 8.5 billion years ago. The red galaxies at the center of the image from NASA's Spitzer make up the heart of the galaxy cluster.
Scores of baby stars shrouded by dust are revealed in this infrared image of the star-forming region NGC 2174, as seen by NASA's Spitzer Space Telescope. Found in the constellation Orion, NGC 2174 is located around 6,400 light-years away.
