A Silent and Beautiful All-Sky Aurora Borealis Time-Lapse
This beautiful silent time-lapse from Stéphane Guisard shows Aurora Borealis in the skies over Yellowknife, Canada. Discover Magazine's Bad Astronomy blog describes what you're watching:
The slowly-moving stars of the Big Dipper and other constellations take a back seat (nearly literally) to the eerie green and red glowing ribbons created when the Earth’s magnetic field fires subatomic particles down into our atmosphere. Of course, when the three-week-old Moon rises, it dominates the scene, but not for long...
Finally, as the video draws to a close you can see Venus hanging just behind the sickle of Leo’s head, a sure sign the Sun won’t be long to rise. And on cue it does, lighting the sky and washing away the glory of the magnetic storm going on overhead.
