This picture shows active regions 2108 and 2019 as they prepared to disappear from view from behind the Sun. This picture wasn’t taken by a spacecraft or a large telescope array, but by the astrophotographer Alan Friedman; a fellow who specializes in solar photography.

These images were captured using hydrogen-alpha light, and it has been false colored using a Ha color pallet. In addition to the two dark sunspots, you can also see the light haze of the Sun’s corona (which is basically the solar atmosphere – I wouldn’t suggest trying to breath it). Inside the corona, there are some solar prominences standing several Earth diameters tall.

Alan has some fantastic images of the Sun, and other astronomical objects. Check some of them out.
