Gallery: The Infrared Universe Seen by Spitzer Telescope

Ultra-Red Galaxies in the Distant Universe

David A. Aguilar (CfA)

This artist's concept shows four extremely red galaxies that lie almost 13 billion light-years from Earth. Discovered using NASA's Spitzer Space Telescope, these galaxies appear to be physically associated and may be interacting. One galaxy shows signs of an active galactic nucleus, shown here as twin jets streaming out from a central black hole.

This infrared image from NASA's Spitzer Space Telescope shows the Helix nebula, a cosmic starlet often photographed by amateur astronomers for its vivid colors and eerie resemblance to a giant eye.

Sculptor Galaxy
