Explanation:
These silvery blue waves washing over a tree-lined horizon
in the eastern French Alps are noctilucent clouds.
From high in planet Earth's mesosphere, they reflect sunlight in
this predawn skyscape
taken on July 8.
This summer, the night-shining clouds are not new to the
northern high-latitudes.
Comet NEOWISE is though.
Also known as C/2020 F3, the comet was discovered in March by the
Earth-orbiting
Near Earth Object Wide-field Infrared Survey Explorer
(NEOWISE) satellite.
It's now emerging in morning twilight only just visible to the unaided eye
from a clear location
above the northeastern horizon.
