The "light show" was so beautiful that astronauts took rare aurora photos on the International Space Station.
CTOnews.com, March 2 (Xinhua) astronaut Josh Kasada (Josh Cassada), who is on a mission to the International Space Station, shared a stunning photo of the aurora in his latest tweet and said "Absolutely unreal" (too beautiful to be true).
People living in the North Pole or South Pole are easier to see the aurora, but it is not easy to see the "light show" presented by the earth in space.
In CTOnews.com, when solar storms rush through space toward the earth, some energy and small particles can enter the earth's atmosphere along the magnetic field lines of the north and south poles. When this happens, particles interact with gases in our atmosphere, causing gorgeous lights, or auroras, in the sky. Oxygen emits green and red light, while nitrogen emits blue and purple light.
