A selfie that's literally out of this world
(CNN) — Have you seen this selfie yet? Its out of this world, literally!
That’s astronaut Rick Mastracchio. He’s at the International Space Station.
Mastracchio posted this awesome shot of himself with the earth and it's horizon in the background on Twitter Wednesday.
He was on a spacewalk outside of the ISS at the time he snapped the picture.
He says the spacesuit he's wearing makes it hard to take selfies in space.
