Aurorae are rare. Pulsating aurorae, whose structures fade in and out of existence, are rarer, still. But rapidly pulsating aurorae, like that featured in this video by French astrophotographer Stéphane Vetter (previously), are among the least common of all. This footage is not a time-lapse; the colors in this video…
The aurorae here on Earth are a pretty impressive sight to behold, but, just like Earth, it turns out that Mars also has aurorae visible to the naked eye — with one pretty startling difference.
This is one of the most arresting compilations of landscape and astrovideography we've seen in ages. Titled "Huelux," created by photographer Randy Halverson, the video plays like a greatest-hits reel of natural phenomena in South Dakota, Wyoming and Utah.

Saturn put on an incredible once-in-a-blue-moon show for the Hubble Space Telescope — Hubble was able to view the planet when its rings were edge-on, so that the planet's twin aurorae, its northern and southern lights, were visible.
At first glance, I thought Mathmos has released a new mood light, but that glowing blue image is actually of Saturn, captured by the Hubble telescope. It's a very rare photo, as both poles and rings are visible.
