M 82: A "Space Rainbow"

Caption NASA originale:"NASA's Spitzer, Hubble and Chandra Space Observatories teamed up to create this multi-wavelength, false-colored view of the M82 galaxy.
The lively portrait celebrates Hubble's "sweet sixteen" birthday.

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".
