M82 - Cigar Galaxy - 180312

Messier 82 (NGC 3034), the Cigar Galaxy is a "starburst" galaxy in the constellation Ursa Major (the Big Bear) and is visible along with M81, Bode's Nebula, just off the end of the dipper portion of the Big Dipper in Ursa Major. The galaxy is seen edge-on from Earth, giving it the cigar shape visible through a typical telescope. It is approximately 12 million light-years away.

The starburst activity visible as red wisps of hydrogen emanating from the core is thought to have been triggered by interaction with neighboring galaxy M81.
