A satellite has captured images of “night-shining clouds”, which form at high altitudes and glow after night falls, and NASA has used them to create a new map of the formations.

Aurora borealis, or the Northern Lights, can sometimes collide producing spectacular displays of light according to NASA which deployed cameras around the Arctic to catch the phenomenon.

Since the collapse of the Soviet Union, the Russian space program has been working closely with NASA. But current Sino-American relations in space are basically non-existent.
