Auroras

Northern lights in the American South, clusters of huge geomagnetic storms—the Sun is throwing a tantrum right on schedule.

As our day star enters its most active period, look for more opportunities to catch these spectral northern (and southern) lights. Here's how.

From seeing the northern lights aboard a Navy ship in Norway to braving the cold for a glimpse of a blood moon.

A curated collection of images shows why this natural phenomenon has fascinated and inspired humans for millennia.

What looks like a ghostly blue hand creeping up on a spaceship is actually a special edition of one of nature’s greatest light shows.

The mysterious phenomenon resembles green sand dunes in the sky.

It's way cooler than an aurora.

Thanks to citizen scientists, this aurora is anthropomorphic.

They think it might have been the largest ever seen.
