Aurora: Earth puts on a show

By Paul Wallis     Jul 19, 2007 in Science
This, you haven’t seen before. Lady Earth can look pretty glamorous, but every so often she really dresses up. Those nice people at the International Space Station caught her in action. No doubt what her favorite color is, either.
Gives you some idea of the sheer scale of the aurora. Down there is quite a lot of northern Canada. That large circle is the Manicougan Impact Crater which is 70km in diameter, in solid rock, which is no trivial event itself. Compare that to the size of the aurora.
Nature doesn’t need a lot of blurb. I sometimes wonder how many APOD links you could follow before you bookmarked an encyclopedia.
