Dwarf Galaxy IC 10
The galaxy IC 10 was discovered on 8th October 1887 by the American astronomer Lewis Swift with the 16 inch Clark refractor of the Warner Observatory in Rochester, New York. The description in Dreyers «Index Catalogue» released in 1805 reads as follows: «Faint stars involved in extremely faint, very large nebulosity». [277, 314]
IC 10 is an irregular dwarf galaxy, like our Milky Way or the Andromeda galaxy. It belongs to the local group. Distances range from 0.6 Mpc to 0.8 Mpc (1.9 to 2.6 million light years).  It is the closest starburst galaxy to us. A large number of young stars are actively being formed here, powered by hydrogen gas, which collects in extensive molecular clouds.  The galaxy is only about three degrees from the galactic equator (plane of the Milky Way), which is why the view in the visual area is severely impaired by the interstellar gas and dust.
