Messier 82(kent asNGC 3034,Cigar GalaxyorM82an aw) is the prototype[5]nearbystarnburst galaxyaboot 12 millionlicht-yearsaway in theconstellationUrsa Major.The starburst galaxy is five timesmair luminousnor the wholeMilky Wayan 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]
