M82
Messier object 82, the Cigar Galaxy
Messier Object 82 (also known as Cigar Galaxy, NGC 3034, or M82) is a starburst galaxy in the Ursa Major constellation.
The Chandra X-ray Observatory detected fluctuating X-ray emissions from the sector, appoximately 600 light-years away from the centre of the messier object — around 12 million light-years from Earth. Astronomers have postulated that M82 would contain the first known mid-mass black hole, of roughly 500 solar masses.
