Earth at night, as seen from the ISS

What can the members of the International Space Station staff possibly do when they are not conducting cool zero-gravity experiments or cleaning up the mess? They look through the window and take spectacular pictures. These time lapse videos show the dense urban areas and the desert parts of the planet, as well as atmospheric phenomena, such as lightening and aurorae.

Numerous other amzing pictures are available on the NASA's website.

Blue Currents

This is a computer animation of ocean surface currents based on satellite observations.

Apart from being pretty, it shows how heat is transported across the planet  (influencing the local climats) and where CO2 is likely to be diluted and stocked. It also helps to track polluted waters.

The current lines remind me of the way Van Gogh sometimes painted clouds:

Nuit étoilée, Vincent Van Gogh, juin 1889
