European Space Agency astronaut Alexander Gerst captured this photograph from the International Space Station and tweeted "Words can't describe how it feels flying through an #aurora. I wouldn't even know where to begin..." Not many can share his experience, but photographer Paul Williams captured an aurora while on a flight from London to New York (stills on Flickr).

Auroras Underfoot is a short documentary about auroras by NASA, which uses high-definition images taken by International Space Station science officer Don Pettit of aurora from orbit. Pettit writes about the difficulties of taking photographs from orbit and other subjects on his blog.
