Explanation: What would it be like to orbit the Earth? The International Space
Station [5]  (ISS) does this every 90 minutes, and sometimes the astronauts on
board take image sequences [6]  that are made into videos [7] . The featured
time-lapse video [8]  shows many visual spectacles of the dark Earth [9]
below. First, as the video begins, green and red auroras [10]  are visible on
the upper left above white clouds. Soon city lights come into view, and it
becomes clear [11]  you are flying over North America [12] , eventually
passing over Florida [13] . In the second sequence you fly over Europe [14]
and Africa [15] , eventually passing over the Nile River [16] . Brief flashes
of light are lightning [17]  in storms [18] . Stars far in the distance can be
seen rising through the greenish-gold glow [19]  of the Earth's atmosphere
[20] .
