NASA astronauts photograph Northern Lights from ISS

Photos posted on Kelly's Facebook page show the astronauts' views of the Aurora Borealis. The extraordinary pictures were said to be taken while Kelly taught Peake how to use his Nikon camera.

The natural light display they captured happens when a burst of the sun's gas and magnetic field causes a solar wind -- the stream of energy specks from the sun.

That stream hits the Earth's atmosphere and creates the Northern Lights' effect.
