M82 - Galaxy in Ursa Major

 
M 82 is located approximately 11.4 million light years away in the constelllation of Ursa Major. It is often referred to as the Cigar Galaxy due to its elongated shape and whispy filaments. It was classifed as an irregular galaxy until 2005, when spiral arms were detected at near infrared wavelenths. The galaxy's center is 100 times more luminous than our Milky Way. Much starburst activity is taking place there (10 times more than the average galaxy). This is believed to be due to its interaction with M 81 (Bode's Galaxy).
