Contributing to what is already an interesting pair of galaxies is an exciting new supernova. Known as SN 2014J, it is the closest observed supernova of its type in over 40 years. Because of its relatively close proximity to Earth (around 11.4 million light years), it is bright enough to be easily captured by amateur and professional astrophotographers alike.

The supernova is expected to peak in brightness around February 4t...
