The Ghost Nebula is located in the "W"-shaped constellation Cassiopeia. It's easy to see how it earned its spooky nickname thanks to what NASA poetically calls its "flowing veils of gas and dust."
"The nebula is being blasted by a torrent of radiation from a nearby, blue-giant star called Gamma Cassiopeiae, which can be easily seen with the unaided eye at the center of the distinctive 'W' asterism that forms the constellation," says NASA.
ESA says the star's ultraviolet radiation bombardment is causing the nebula to slowly dissipate, which only adds to its ghostly mystique. This is possibly the most detailed image ever taken of IC 63, the agency notes, and highlights Hubble's impressive imaging abilities.
