| Notes: |
IC 10 is an irregular dwarf galaxy in the constellation
Cassiopeia. It was discovered in 1887 and its
membership in the Local Group of galaxies was finally confirmed in 1996.
This galaxy is the only known starburst galaxy in the Local Group of
galaxies. Despite its closeness, the galaxy is rather difficult to study
because it lies near the plane of the Milky Way and so IC 10 is heavily
obscured by interstellar matter. You can see some dust in
the OSC widefield image. The dense dark nebula
complex around vdB 1 can be found in the
neighbourhood in a distance of only 80'. IC 10 is surrounded by a faint halo, as can be seen clearly in the above image. This circular halo has a diameter of more than 12', what nearly doubles the apparent size in visible light, known from literature. IC 10 is even bigger. This galaxy has a huge envelope of hydrogen gas, with an apparent size measuring 68′ × 80′. |
