See the beautiful and mysterious Noctilucent clouds (Night Shining Clouds) that were filmed by Casper Rolsted during the summer of 2019. Noctilucent clouds are formed by ice crystals in the thin air approximately 83 kilometers above the Earth. The temperature needs to drop below -120°C before the noctilucent clouds can form during the northern hemisphere summer. You might also like to see the Northern Lights In Finland.
