There is a picture at the top of this link that I query:

If you look at it, the night sky appears to glow rather green in places especially on the right hand side just above the horizon. Is that just false color? If not, where does that green light come from? Is it light pollution? -seems a bit odd for it to be green! Or does parts of the Milky way as we see it in the sky sometimes look greenish and, if so, why?
