An astronaut snapped a jaw-dropping picture of this week’s aurora borealis from space. NASA’s Josh Cassada captured the light display aboard the International Space Station (ISS), while it was 250 miles from Earth.
Seemingly at a loss for words, the Minnesota-born physicist and US Navy test pilot commented on Tuesday, calling it “absolutely unreal”. An aurora is a natural light display in Earth’s sky, predominantly seen in high-latitude regions around the Arctic and Antarctic.
They are the result of disturbances in the magnetosphere caused by the solar wind. Auroras display moving patterns of brilliant lights that appear as curtains, rays, spirals, or dynamic flickers covering the entire sky—the way only a photo like Josh’s can portray.
