         Object M82 - Cigar Galaxy
         Comment Messier 82 (aka M82, NGC 3034, Cigar Galaxy) is an irregular galaxy located in the constellation Ursa Major. The galaxy is undergoing a star burst where strong stellar winds from thousands of energetic new stars in the dense galactic core expel hot gases that extends outward. This is visible as folds of red ionised hydrogen alpha gas. The galaxy is considered irregular in shape, potentially due to a recent interaction with its galactic neighbour M81. M82 is 12,000 light-years distant.
