Nearly 12 million light years away in the constellation Ursa Major is the M82 galaxy. The above false-coloured view of the galaxy was a combined effort by NASA's Spitzer, Hubble and Chandra observatories.
X-ray data recorded by Chandra appears in blue; infrared light recorded by Spitzer appears in red; Hubble's observations of hydrogen emission appear in orange, and the bluest visible light appears in yellow-green.
