Astronaut Scott Kelly is spending a year in space, while his twin brother, Mark Kelly, lives backs on Earth. The two are a part of a NASA study to see how space affects the human body.

While aboard the International Space Station, Scott Kelly snapped this photo.

He tweeted, "I've never seen this before- red #aurora. Spectacular! #YearInSpace"

Not a bad view aboard the ISS.
