Emission nebula IC 1848. North is at top. This is a huge cloud of gas and dust that glows as the hydrogen that it contains is ionised by radiation from the hot young stars that formed within it. The nebula contains several star clusters,which formed from the gravitational coalescence of the nebula's gas. The nebula lies around 7000 light years from Earth in the constellation Cassiopeia.
