Description

My wife calls it a brain, which is fine I guess, but it's really an emission nebula formed by winds from Wolf-Rayet star WR-136 ramming into gas that the star expelled when it was a red giant. Red is hydrogen alpha, and blue is OIII. This was a teeny section of the image of the Cygnus region around Sadr that I took last month.
