The Astro pic of the Day for August 15th. With all the Mars news this week, this was probably the most compelling of all the images that were offered by various folks. Partly because it's fairly recent, from June of this year.

The crater, on the Mars surface, is 2.3 km (1.4 mi.) wide. It's visually confusing, but the layers of sediment that make up the "swirls" are highest in the MIDDLE of the crater.

The work of figuring out how those layers came to be is left as an exercise for the reader.
