Out-of-this-world cosmic shots from the International Space Station: photos

NASA astronaut, Donald Pettit, has gained a distinguished reputation for his show-stopping photography from the International Space Station. Now safely returned to Earth, the spaceman has taken time to reveal more of his incredible pictures. Pettit has completed four spaceflights, accumulating a total of 590 days in space, making him one of NASA’s most experienced astronauts. His last mission saw him spend 220 days on the station, before landing in Kazakhstan on April 20, which was also his 70th birthday.
