This gorgeous video of the Northern Lights over Earth — shot by astronauts on the International Space Station (ISS) — really puts things in perspective. Check it out.

One of my favorite sites, space.com, did an extraordinary piece on this. An excerpt:
The four-minute video combines several sequences of time-lapse imagery snapped recently by astronauts aboard the International Space Station. It takes viewers around the world, above dramatic lightning storms and through dazzling displays of the northern lights, also known as the aurora borealis. One such light show over the United States and Canada features prominently near the beginning of the video. The boundary between Earth and space appears to be aflame as the flickering green lights dance and roll over great swaths of the Northern Hemisphere.
And here is a shot taken by the same ISS astronauts of the Southern Lights. Wow.
NASA wrote this about that still: A still from a new video shot by astronauts aboard the International Space Station. This shot shows the southern lights over the Indian Ocean.
