NASA unveils greatest views of the aurorae ever (Synopsis)

"You cannot rob me of free nature's grace,
You cannot shut the windows of the sky
Through which Aurora shows her brightening face." -James Thomson

The northern (aurora borealis) and southern (aurora australis) lights are caused by a combination of three phenomena on our world, that make our aurorae unique among all worlds in our solar system:

  1. Outbursts from the Sun that can go in any direction,
  2. Our magnetic field, that funnels charged particles into circles around the poles,
  3. And our atmospheric composition, that causes the colors and the displays we see.

Put all of these together and add in a 4k camera aboard the ISS, and you’ve got an outstanding recipe for the greatest aurora video ever composed.

Here's the in-depth science behind it, too, only from me and Starts With A Bang!

Having seen Borealis for many years out of Toronto, I appreciated the lights whilst living there. Thanks for the aerials; just a different and pleasant visual - brings back the memories.

I remember seeing the first images caught by a new, super sensitive video camera which was (finally) sensitive enough to capture the Aurora, blurrily, on magnetic tape instead of film. These are amazing, I want to see more, from higher up!
