Around the World in 90 Minutes

EXPLANATION

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. Please help create a useful companion guide for this moving video by identifying landmarks, cities, countries, weather phenomena, and even background constellations that appear.
