A snap-happy astronaut captured this incredible shot of San Francisco's Golden Gate Bridge from his perch hundreds of miles above the earth on board the International Space Station.
Commander Chris Hadfield, 53, has posted hundreds of breathtaking images on his Twitter account since joining the crew as part of Expedition 34 just a few weeks ago.
As well as San Francisco's famous landmark, Commander Hadfield - who has described the shifting view of the earth from windows of the space station as 'a perpetual magnet' - has snapped the bright lights of Manhattan at night, the 'endless' golden beaches of Australia, a vivid blue river snaking through Brazilian farmland, and 'cauliflower' clouds sitting over the Amazon rainforest.
