NASA channels Warhol in these ultraviolet images of the sun, posted today. The non-artistic reason for the differing color spectrums is to show off a reversed-polarity sunspot, on the left. This sunspot marks the end of another cycle of waxing and waning solar flares, meaning the sun will begin climbing towards Solar Max, which it will reach in 2011 or 2012. Sidenote: wouldn't Solar Max be a good superhero name?
