Messier 82, the cigar galaxy is an irregular shaped galaxy found 12 million light years away. It was discovered by Johann Elert Bode on the same night as M81. This cigar shaped galaxy is a starburst galaxy due to its interaction with M81. Starburst galaxies produce stars at a much higher rate than the Milky Way. This is usually caused by an interaction with a nearby galaxy. M82 also contains an unknown object with a radio signal that is unexplainable and has not been seen anywhere else in the universe.
