The Ghost Nebula


The Ghost Nebula (aka IC 63) is located 550 light-years away in the constellation Cassiopeia the Queen. The nebula’s glow reminds some people of the apparitions reported by paranormal investigators. In reality, it’s simply radiation from hydrogen that is being bombarded with ultraviolet light by the nearby blue-giant star Gamma Cassiopeiae (not seen in this picture). The blue light is starlight reflected by the nebula’s dust.
