Cone Nebula NGC2264 thumbnail
The cone's shape comes from a dark absorption nebula consisting of cold molecular hydrogen and dust in front of a faint emission nebula containing hydrogen ionized by the brightest star of NGC 2264. The faint nebula is approximately seven light-years long and is 2,700 light-years away from Earth.
