Pan across a cosmic ghost
This video pans across the nebula IC 63, often nicknamed the Ghost Nebula. This nebula is classified as both an emission and a reflection nebula.
The hydrogen within IC 63 is being bombarded with radiation from the nearby star Gamma Cassiopeiae, causing its electrons to gain energy which they later emit as hydrogen-alpha radiation — visible in red in this image.
The blue parts of IC 63 are created by dust particles in the nebula which reflect the light from Gamma Cassiopeiae.
