Re: APOD: Fireworks Galaxy NGC 6946 (2011 Jan 01)
Question about the image: at about the four-o-clock position, there is a circular ring of stars aroung a group of huge blue stars. Based on the size of the galaxy, this ring is huge! What could have created such a nearly circular structure? It seem way too big to be a super-nova remnant.
