Messier 82 (M82) is a luminous infrared galaxy about twelve million light-years away from the Milky Way. Its burst of star formation powers the radiation and drives a bipolar superwind that originates near the core of the galaxy. The wind extends perpendicular to the galactic plane out into the halo and intergalactic medium; ionized gas in the wind traces a continuous structure that is about thirty-four thousand light-years long. Astronomers think that star formation along the superwind is exciting the gas and also generating X-ray emission, the latter produced by associated shocks.
