Description

The Ghost (IC 63 & IC 59) is an  extremely faint emission and reflection nebula in the Northern constellation of Cassiopeia at a distance of 550 light years from Earth. The nebula is crafted by the intense stellar winds of the central blue supergiant star γ Cas. This star is 19 times more massive and 65.000 times brighter than our Sun. The hydrogen within IC 63 is being bombarded with ultraviolet radiation from Gamma Cassiopeiae, causing its electrons to gain energy which they later release as hydrogen-alpha radiation — visible in red in this image. IC 59 exhibits a blueish color due to the fact that it reflects starlight from the massive star.
Both nebulae are being eroded by the intense winds of Gamma Cas and in time, will probably disappear.
