IC10 Starburst Galaxy

IC10 Starburst Galaxy

IC10 is a irregular galaxy in the constellation Cassiopeia. IC10 is the only known Starbrust galaxy in the local group of galaxys. The galaxy is approxmatly 2.3 million light years from Earth, and about 5000 light years accross. The apparent distance between IC 10 and the Andromeda Galaxy is about the same as the apparent distance between the Andromeda Galaxy and the Triangulum Galaxy, which suggests that IC 10 may belong to the M31 subgroup. Despite its closeness, the galaxy is rather difficult to study because it lies near the plane of the Milky Way and is heavily obscured by interstellar dust. The galaxy has a huge envelope of hydrogen gas, with an apparent size measuring 68′ × 80′, which is far larger than the apparent size of the galaxy in visible light (5.5′ × 7.0′). IC 10 is also unusual in the respect that the visible part of the galaxy seems to rotate in a different direction than the outer envelope.
