The longest partial lunar eclipse of the 21st century will take place overnight on November 18 and 19, 2021. And if you’re in North America, you’re golden: You’ll be able to see the entire eclipse, which NASA predicted will last three hours, 28 minutes, and 23 seconds.

While the must-see celestial event is technically a partial lunar eclipse, the experts at astronomy website EarthSky explain that “With a just thin sliver of the moon exposed to direct sun at maximum eclipse, the rest of the moon should take on the characteristically ruddy colors of a total lunar eclipse.”
