IC 10 is a dwarf irregular galaxy in the constellation of Cassiopeia. It
is the only known starburst galaxy in the Local Group of galaxies
and has a distance of about 3 million lightyears. It lies in the galactic
plane and all the bright stars in the image are foreground stars
belonging to the Milky Way. The morphology and absolute size of IC
10 is similar to our neighbour galaxy SMC (Small Magellanic Cloud).
The diffuse yellowish areas consists of older stars. The red filaments
which emit most of their light in the H-alpha line are HII regions with
ongoing star formation. It has apparent dimensions of 6.8 x 5.9 arc
minutes and an apparent magnitude of 10.4.
