These electrifying noctilucent clouds were captured in the sky of Nykøbing Mors, Denmark on June 13, 2016 in the morning hours.
Look at these awesome night clouds by Ruslan Merzlyakov.
Noctilucent clouds are tenuous cloud-like phenomena that are the “ragged edge” of a much brighter and pervasive polar cloud layer called polar mesospheric clouds in the upper atmosphere, visible in a deep twilight.
Night clouds are the highest clouds in Earth’s atmosphere, located in the mesosphere at altitudes of around 76 to 85 kilometres (47 to 53 mi).
They are normally too faint to be seen, and are visible only when illuminated by sunlight from below the horizon while the lower layers of the atmosphere are in the Earth’s shadow.
Noctilucent clouds are not fully understood and are a recently discovered meteorological phenomenon; there is no record of their observation before 1885.
Noctilucent clouds can form only under very restricted conditions and their occurrence can be used as a sensitive guide to changes in the upper atmosphere.
