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.
