What are the rare clouds that glow?

More Facts About Noctilucent Clouds

Noctilucent clouds or NLCs are Earth's highest clouds in the sky, literally glowing at the edge of space in the atmosphere's mesosphere layer, a high cold layer that is, according to NASA, “one hundred million times dryer than air from the Sahara desert.”

How rare is a pink cloud?

The rarity of this gorgeous event is dependent on the latitude of where you are in the world, and weather conditions.

What is the weirdest looking cloud?
