The Ghost Head Nebula is located 168,000 light-years away.

This #HubbleClassic image reveals a dense region of star formation. The two ‘eyes’ in the ghost's ‘head’ glow bright white in a glowing yellow void: they are very hot and glowing droplets of hydrogen and oxygen.

Hubble's high resolution allowed astronomers to study in detail various features in the nebula to better understand the processes by which massive stars form in this interesting region.

Does he look like a ghost to you? Hello, Casper!
