Via the BB Submitterator, Chris Combs says:
Following up on a previous Boing Boing post: last week, our sun's hot plasma shot a billion tons of energetic particles towards Earth, which led to some amazing aurora borealis. I was thrilled to see a fine batch of northern lights photos on Flickr, and even more excited that their creators gave us permission to run them on National Geographic News. And—there could be more coming tonight, thanks to a Saturday solar flare! Enjoy!
