IC 59 and IC 63, collectively known as the Ghost of Cassiopeia, are a pair of faint reflection nebulae situated in the constellation Cassiopeia. These nebulae are primarily illuminated by the light of Gamma Cassiopeiae, a variable star with a powerful stellar wind. IC 59 and IC 63 owe their ghostly appearance to the scattering of starlight by dust particles in the interstellar medium, giving them a wispy and ethereal aspect.
