Aurora from Space

Explanation: From the ground, spectacular auroras seem to dance high above. But the International Space Station ( ISS ) orbits at nearly the same height as many auroras , sometimes passing over them, and sometimes right through them. Still, the auroral electron and proton streams pose no direct danger to the ISS . In 2003, ISS Science Officer Don Pettit captured the green aurora, pictured above in a digitally sharpened image. From orbit, Pettit reported that changing auroras appeared to crawl around like giant green amoebas . Over 300 kilometers below, the Manicouagan Impact Crater can be seen in northern Canada, planet Earth.
