This has to be one of the coolest videos I’ve seen in a while. It’s a time lapse video of photos taken from the International Space Station, shot at 1fps. (Best viewed in full-screen, as the embedded version simply doesn’t do it justice…)
The author says “[t]he yellow/greenish line that you see over the earth is Airglow.” For the full details, including the locations shown, see the description under the video on the original vimeo page.
