The International Space Station (ISS) Expedition 20 crew looked toward the Earth's limb (the hazy blue line on the horizon) and snapped this impressive photograph of stormy weather over Brazil. A huge amount of detail has been captured by the station's Nikon D2Xs digital camera as a part of the ongoing ISS Crew Earth Observations experiment.

Cumulonimbus clouds in various stages of development can be seen in the unstable air of the tropics, causing thunderstorms. Ring-like patterns in the large-scale structure of the stormy cloud cover is evident, possibly generated by the storm activity. The snaking 2,100 mile (3,380 km) long Rio Madeira (Madeira River) in the Amazon Basin can also be seen, glinting in reflected sunlight.
