What Are The Rarest Forms Of Cloud? [Solved]

Wow! These noctilucent clouds are really something special - they form way up in the mesosphere, the highest layer of atmosphere. And they’re super rare too - you don’t see them every day. Plus, they’re made of tiny ice crystals that reflect sunlight, so they look like a beautiful silver-blue color in the night sky. Amazing!
