This is how a sunspot really looks, in the most detailed picture of the surface of the sun yet. Hola, Señor Sauron!
The photo, which was taken on July 2 by New Jersey Institute of Technology's Professor Philip R. Good and the Big Bear Solar Observatory team, shows a sun spot at about 3600ºC, surrounded by a mosaic of hell burning at 5800ºC. The BBSO is 5.25-feet in diameter and will be able to resolve sun details as small as 45 kilometers in optimal conditions. The image itself shows details measuring 0.09 arcseconds, which is about 65 kilometers (about 40 miles). [Cielespace]
