SN 2014J is the name given to a nearby supernova in the galaxy M82. On January 21, 2014, Dr. Steve Fossey was teaching a group of undergraduate students how to observe with a telescope when they decided to observe M82. They noticed a bright, starlike object that did not appear in previously taken online images of the galaxy. It was officially designated SN 2014J. Supernovae (the plural form of the Latin-based “nova”) are named based on the year the supernova was first observed and given a letter based on the order in which it is announced. Thus, SN 2014A was the first supernova observed in 2014 to be given an official name, and SN 2014J was the tenth. After 26 supernovae, two letters are used, continuing with the pattern aa, ab, through az, and then continuing with ba, bb, and so on. Hundreds of supernovae are now discovered each year.
