A Chrome Extension That Replaces 'Cloud' With 'Butts' Wins Everything

Earlier today, we asked you to tell us about all your favourite Chrome extensions.

Amazing Cloud Waves Herald The Alien Invasion Apocalypse

Looking at these time-lapse videos of Undulatus asperatus — a cloud formation proposed as separate cloud classification in 2009 — look like the ocean’s surface in a stormy day as seen from under the water.

Watch A Massive Thunderstorm Form In This Timelapse

Man, this looks like some end of the world type weather. It’s the type of thunderstorm I’d see in a movie and think the CGI was too fake.

Antarctica Looks Like A Mystical Land Shrouded In Lenticular Cloud

This might look like result of some pro-level CGI, or perhaps even a glimpse into your imagination, but in fact it’s a photograph taken in Antarctica just this last week. As part of Operation Ice Bridge — a multi-year mission to monitor conditions in Antarctica and the Arctic — NASA researchers have just been on a week-long ice-surveying mission. Along the way, they took plenty of photographs.

The sky is blue! Only when it’s not grey. Or purple. Or red. Or orange. The clouds are white! Only when they’re not grey. Or even darker than that. Basically, the clouds and sky can be anything. But can the sky be an orange bubbly thing that looks like we’re on an alien planet? Apparently so.

This Is What Gravity Looks Like
