Interesting photo

I saw this picture on the universe today site. (here)

The article is interesting, and the picture a spectacular image of aurora from space, but look toward the lower center and you see a ring shape. As best I can tell, this is the Manicouagan crater in Canada. (here is a link to a detailed picture - see if you think it is the same one as well) It is the remains of an impact some 214 million years ago and is about 100 km (about 62 miles) across. What is visible in the photo is the inner ring, about 70 km across. It is one of the largest impact craters known. It would have created quite the extinction event. I just thought it odd that they happened to capture an image of this crater at the same time they were photographing the aurora.

Very nice picture!
Now I have to go crater hunting!

Have some pearls for the pic.
