As the International Space Station orbits Earth, it snaps images from a still camera affixed to its underside. String them together, and you get views of terrestrial phenomena as you've never seen them before. In this case, it’s the Aurora Borealis.
The sun is in an active phase right now, leading to displays of "Northern" lights as far south as Alabama.
Just a little reminder that there's no point in trying to save the planet if we don't occasionally pause to enjoy it.
