Holy wow! What an astonishing sight that must be. And did you see the object moving right-to-left a few seconds in, just above the green airglow layer? I suspect that was a low-Earth satellite in a different orbit, moving in a different direction. The storms over a dark Australia below make this video that much more dreamlike.
But it's real. A comet found by an amateur astronomer, observed the world around -- and above -- and then seen and photographed from space by a man floating in an internationally designed and built habitat in orbit.
That is, quite simply, very cool.
