ON FRIDAY, EARTH will engulf the moon in its shadow and create the longest total lunar eclipse in this century: a full 103 minutes. The next one that comes close won’t happen until 2029. And today’s running time won’t be matched until 2123. In a nice little cosmic reminder that nobody is the center of the universe, this eclipse will be visible from every continent on earth except North America. If you want the best view and can’t catch a flight to Eastern Africa, India, or Southeast Asia—ideal viewing locations, according to NASA—you’ll have to live-stream the eclipse instead.
