Oh that is odd. If you go into examine you can see it's near the edge of the SDSS survey (zoom out a bit on Sky server)

So I wonder if there is only a good green (r-band) image there - hence the odd green look.

In fact if you keep going through to NED (NASA Extragalactic Database) you can see it is a #planetarynebula cool!

So it's could really be green because of the strong emission lines which fall in the r-band filter of SDSS.

A luminous doughnut!
If it's an SDSS image it's presumably just gone through the green filter? Like one end of an asteroid?Posted
