The shimmering atmospheric lighting displays known as auroras have never looked sharper than in a new NASA video.

A dark, moonless sky is awash in light radiating from an aurora over Antarctica in a new image released by NASA.

Thanks to Twitter, the chances of spotting the aurora borealis are getting better, a new study reports.

The solar storms currently affecting Earth have created stunning northern lights displays for skywatchers.

Stunning images of the night sky from around the world show everything from swirling green auroras and star trails to the bulging Milky Way galaxy and the Big Dipper constellation.
