November 23, 2009--A product of cosmic collaboration, this new picture of the Crab Nebula combines data from the Chandra X-ray Observatory, the Hubble Space Telescope, and the Spitzer Space Telescope. The nebula is the remnant of a stellar explosion 6,000 light-years from Earth that was so powerful people saw the burst in A.D. 1054, according to NASA.

Infrared light caught by Spitzer and visible light seen by Hubble paint the nebula's expanding debris cloud in shades of purple and red. Meanwhile, Chandra's x-ray vision is helping astronomers understand the high-energy particles (seen in blue) coming from the dead star's core, known as a white dwarf.
