Around the World in 90 Minutes

What is it like to circle the Earth? Every 90 minutes, astronauts aboard the
International Space Station experience just that. Recently, crew members
took a series of light-sensitive videos looking down at night that have been
digitally fused to produce the above time-lapse video. Many wonders of
the land and sky are visible in the eighteen sequences, including red aurora
above green aurora, lights from many major cities, and stars in the background.
Looming at the top of the frame is usually part of the space station itself,
sometimes seen re-orienting solar panels.
