On board the International Space Station (ISS), German astronaut Alexander Gerst took the opportunity from space to capture a photo of Earth blanketed with cloud cover.
Gerst is a geophysicist and volcanologist on his second mission on the ISS, and his first as a mission commander.
He recently appeared live from the station, making a guest appearance at a concert performed by electronica band, Kraftwerk.
