IC 63 Ghost Nebula Caption: Powerful gushers of energy from seething stars can sculpt eerie-looking figures with long flowing veils of gas and dust. One striking example is "the Ghost of Cassiopeia," officially known as IC 63, located 550 light-years away in the constellation Cassiopeia the Queen. Credits: NASA, ESA, and STScI Acknowledgment: H.
