Messier 82, also known as the Cigar Galaxy, is a starburst galaxy located in the constellation Ursa Major. Discovered by the German astronomer Johann Elert Bode in 1774 and later independently cataloged by Charles Messier in 1781, Messier 82 is a member of the M81 Group of galaxies. Positioned approximately 12 million light-years away from Earth, it is interacting gravitationally with its neighbor, Messier 81.
Messier 82 is characterized by its irregular shape and intense star-forming activity. The starburst phenomenon is a result of gravitational interactions with Messier 81, which triggers the formation of massive stars in Messier 82’s central region. Observations of Messier 82 provide astronomers with valuable insights into the processes of galactic evolution, the impact of interactions between galaxies, and the energetic events associated with star formation.
The Cigar Galaxy is a popular target for astronomers studying extreme star-forming regions and galactic interactions. Its turbulent and dynamic nature makes it a fascinating subject for research and contributes to our understanding of the complex interplay between galaxies in cosmic neighborhoods. Messier 82, with its unique features and connection to its gravitational companion Messier 81, adds to the ongoing exploration of the diverse range of galaxy interactions and their role in shaping the evolution of galaxies.
