  Located in the constellation of Cassiopeia IC10 is classified as a dwarf irregular galaxy that is a member of the Local Group of galaxies. It is also referred to as a starburst galaxy and is the most active star formation galaxy in the group. Compared to the Small Magellanic Cloud (SMC), IC10 has a larger number of Wolf-Rayet stars. IC10 lies near the galactic plane of the Milky Way and due to interstellar matter exhibits a reddening hue. The yellow and green emissions are from older stars. The red filaments are H-alpha regions with active star formations.
