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.
