Earthlings lucky enough to see the Northern Lights have been captivated by them for centuries.
And it happened again over the weekend, when the clouds opened up enough for the Aurora Borealis to put on a show visible to night owls or early risers on the St. John's University campus in Collegeville.
Take a gander at the video, which was posted by KARE-11:
What's nature doing when it puts on this light show?
A recent feature in the Minnesota DNR's Conservation Volunteer includes an explanation of the magnetics involved, along with a look at how the lights have been perceived over the centuries and tips for spotting the aurora.
Astronomers say the aurora operate in a cycle of about 11 years. We're reaching the peak of one of those cycles, meaning the northern lights should be increasingly visible through October of this year. But, as those cycles go, this is said to be one of the weakest ones of the past century.
The University of Minnesota's physics and astronomy department has a page with lots of links to photos of the aurora and tips for pointers for photographing them.
