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.
