xray galaxy m82 ursa major

Messier 82 (also known as NGC 3034 or the Cigar Galaxy) is the prototype[5] nearby starburst galaxy about 12 million light-years away in the constellation Ursa Major. The starburst galaxy is five times as bright as the whole Milky Way and one hundred times as bright as our galaxy's center.[5]

In 2005, the Hubble revealed 197 young massive clusters in the starburst core.[5] The average mass of these clusters is around 2 ? 105 M, hence the starburst core is a very energetic and high-density environment.[5] Throughout the galaxy's center, young stars are being born 10 times faster than they are inside our entire Milky Way Galaxy.[6]
