Messier 82 (kent asNGC 3034,Cigar Galaxy orM82 an aw) is the prototype[5] nearbystarnburst galaxy aboot 12 millionlicht-years away in theconstellationUrsa Major. The starburst galaxy is five timesmair luminous nor the wholeMilky Way an ane hundrit times mair luminous nor oor galaxy's center.[5] The starnburst activity is thoucht tae be triggered bi interaction wi neighborin galaxyM81.

SN 2014J, an apparentType Ia supernova, wis observed in the galaxy on 21 Januar 2014.[6][7][8]
