This picture was taken from the International Space Station (ISS). NASA says the ISS orbits at the same height as many auroras. "Therefore, sometimes it flies over them, but also sometimes it flies right through. The auroral electron and proton streams are too thin to be a danger to the ISS, just as clouds pose little danger to airplane.” This image shows auroras borealis over northern Canada. NASA reports that changing auroras look like “crawling giant green amoebas” from space.
