NEW YORK — Get ready for a partial lunar eclipse and supermoon.
The spectacle will be visible in clear skies across North and South America on Tuesday night and in Africa and Europe Wednesday morning.
A partial lunar eclipse happens when the Earth passes between the sun and moon, casting a shadow that darkens a sliver of the moon.
Since the moon will inch closer to Earth than usual, it'll be a supermoon.
NASA says the moon "will start entering the Earth's partial shadow" on Tuesday at 6:41 p.m. MDT.
"The slight dimming of the moon will be difficult to notice until the top edge of the moon starts entering the full shadow" at 8:13 p.m. MDT, according to the NASA website. The peak of the lunar eclipse will be at 8:44 p.m.
No special eye protection is needed to view a lunar eclipse. Viewers can watch with the naked eye or opt for telescopes and binoculars.
