This year I saw my first Noctilucent Clouds (NLCs). They were mesmerizing!
Noctilucent clouds, or night-shining clouds, are thin clouds high up in Earth’s atmosphere – the mesosphere – as much as 50 miles (80 km) above Earth’s surface. Scientists think they’re made of ice crystals that form on fine dust particles from meteors. They can only form when temperatures are incredibly low and when there’s water available to form ice crystals.
We see noctilucent clouds when most of the sky has grown dark. But, the rays from the sun can still reach and reflect off these eerie, ethereal clouds. Indeed, they have an electric-blue appearance.
I had some technical difficulties filming this timelapse, but maybe I get another chance to capture them next year with optimized equipment.
