Lucky sky-watchers are about to get a cosmic three-for-one deal, as the second super-size full moon in a month undergoes a dramatic total lunar eclipse on January 31. According to eclipse experts, the event marks the first time anyone on Earth has seen this celestial trifecta in 35 years—and the first time it’s been seen in the Americas in 150 years.
