Caption: The Crab Nebula is an iconic object in space that has been studied intensely by both telescopes on the ground and those in space. This image of the Crab combines data from three of NASA’s Great Observatories. X-rays from Chandra (blue) have been combined with optical images from Hubble (red and yellow) as well as infrared data from Spitzer (purple). Together, these three telescopes provide a striking view of this famous cosmic source.

Scale: Image is 5 arcmin across.
