IC 342 – The Hidden Galaxy IC 342 is a spiral galaxy located in the constellation of Camelopardalis, the Giraffe. It is one of the relatively nearby galaxies to the Milky Way, yet it is surprisingly difficult to observe because it lies behind the plane of our own galaxy. The large amount of stars, gas
