Today’s Image of the Day from NASA Earth Observatory features noctilucent, or luminous, clouds over the North Pole.

These “night shining” clouds appear just after sundown, but float so high in the atmosphere that they are still lit by the sun when it is no longer visible.

This composite image is centered on the North Pole and is based on data obtained by NASA’s Aeronomy of Ice in the Mesosphere (AIM) spacecraft.
