IC 342 - Spiral Galaxy in Camelopardalis


IC 342 (also known as Caldwell 5) lies approximately 10 million light years away in the constallation of Camelopardalis, the giraffe. It spans 60,000 light years, somewhat smaller than the Milky Way. Still, given its relatively short distance from us, it would typically be very conspicuous in the night sky. Its apparent diameter is 21 arcminutes, 2/3 that of the full moon. However, since it lies only 10 degress from the galactic plane, much of its light is obscured by cosmic dust. It is therefore often referred to as the Hidden Galaxy. It was not discovered until 1895, when amateur astronomer William Frederick Denning observed it.
