M81-M82

Messier 81 is located approximately 10° northwest of Alpha Ursae Majoris along with several other galaxies in the Messier 81 Group.[9][25] Messier 81 and Messier 82 can both be viewed easily using binoculars and small telescopes.[9][25] The two objects are generally not observable to the unaided eye, although highly experienced amateur astronomers may be able to see Messier 81 under exceptional observing conditions.[9] Telescopes with apertures of 8 inches or larger are needed to distinguish structures in the galaxy

Messier 82 (also known as NGC 3034, Cigar Galaxy or M82) 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 Space Telescope 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
