The next full moon, known as the Worm Moon, occurs Thursday, March 13, according to the Old Farmer’s Almanac. A full moon will appear full for a couple of days before it moves into its next phase, according to NASA.

Hundreds of millions of Americans will have the chance in March to see the first total lunar eclipse in nearly three years.

A rare blood moon total lunar eclipse is happening in March in the Garden State. The reason it’s called a blood moon is that during a lunar eclipse, the Earth casts a shadow on the moon, blocking direct sunlight. Sunlight not blocked by Earth filters through our atmosphere, and that filtering process gives the moon a reddish-orange color.
