Whether you think it marks the beginning of the apocalypse or is just a neat thing to look at tonight, Live Science has some tips and a timetable for best viewing in your area. The moon enters Earth's full shadow, called the umbra, starting at 9:07 p.m. EDT (6:07 p.m. PDT). The total eclipse begins at 10:11 p.m. EDT (7:11 p.m. PDT). Totality lasts an hour and 12 minutes, at which point a bright sliver of the moon will emerge and grow.
