Video of a strange, rainbow colored yet beautiful cloud was captured in Costa Rica earlier this week.

People of Costa Rica where astonished as they look up to the sky to see a huge rainbow, almost iridescent cloud that hovered over them as most took pictures and wondered what exactly they were looking at.

Apparently these types of cloud formations are super rare and are referred to as ‘cloud iridescence’, which is due to small ice crystals that scatter light and create a rainbow type halo producing their phenomenal appearance.
