M82 (NGC 3034) Cigar Galaxy with Super Nova SN 2014J
Edge-on spiral galaxy in Ursa Major
Dimensions: 11.2 x 4.3 arc-min
Distance: 11.4-12.4 mLy
The bright star in the upper middle of M82 is a supernova SN 2014J which appeared 2014-01-21 at 19.20 UT. That star is in M82 and therefore 12mLy away. All the other bright stars in the image are in our galaxy, so “only” a few thousand light years away.
The left and right images are the same – the image on the right just annotated. (So not a before and after view.)
