I love this shot of the south Pacific Tinakula volcano as seen by the Earth Observing-1 satellite. Tinakula is only sporadically active, and EO-1 caught a plume of steam and some ash from a mild eruption from February 2012.

But it's the water that makes this image so odd and lovely. It's actually natural color; the sunlight is glinting off the water, giving it that silver sheen.
