The frame is called “postcard from the edge of space”.
National Aeronautics and space administration of the USA has published a photo of clouds taken from orbit. Scientists posted the picture to Instagram and wrote that it was “postcard from the edge of space,” reports the Chronicle.info with reference to the Correspondent.
“These clouds of electric blue can only be seen when the sun descends beyond the earth’s horizon and illuminates them,” explained NASA.
The picture was taken from orbit of the International space station at an altitude of about 430 kilometers above the South Pacific ocean.
The researchers emphasized that these clouds are the highest in the atmosphere of planet Earth.
Noctilucent clouds form in the mesosphere of the Earth at a height of about 76 to 85 kilometers, you can see them in the deep summer twilight in latitudes between 50 and 70 degrees North and South latitude.
