Koch, who boarded the International Space Station in mid-March, had participated in her first spacewalk in her life. Recently, everyone on the space station has been busy with scientific research and spacecraft maintenance.

But in his spare time, Koch had the privilege of capturing it.BeautifulAurora moment. It wrote on Twitter: "Years ago, I spent six months in the Antarctic on winter nights looking up at the aurora, and now I see the same shocking and inspiring picture on the International Space Station."

It is reported that according to the location of people on land, aurora is usually divided into the southern and Northern lights, which are caused by charged particles bombarded by the sun in space. When a solar wind carrying large quantities of such particles arrives on Earth, the planetary magnetic field reacts to it, causing part of the atmosphere to glow.

Because the International Space Station orbits the Earth at about 5 miles per second (a circle can be completed in about an hour), viewing the aurora in space is particularly impressive (the chance to capture it is still fleeting).
