Incredible night-time clouds

We’re used to fluffy white clouds on a summer’s day or dark, grey, rain-filled clouds on the remaining 364, but have you ever noticed clouds at night?

They’re called noctilucent clouds and form when the sun shines at a steep angles, bouncing off tiny ice shards just below the Earth’s mesosphere, around 30 miles above the ¬†Earth’s surface. The ice shards slightly scatter the sunlight, which bounces back to us and make it seem like there are clouds in the night sky.

Here is a video showing some of these incredible natural phenomena.
