As March's full Worm Moon rises late Sunday into early Monday, it will travel through the Earth's penumbra — the faint outer part of its shadow — creating a penumbral eclipse.

During a penumbral eclipse, the moon becomes slightly dimmer. Alternatively, during a total lunar eclipse, when the move fully enters the Earth’s shadow, the moon becomes reddish.

The solar eclipse will happen on Monday, April 8. Unlike the penumbral eclipse, only those along the path of totality will be able to see the celestial show.

In a partial lunar eclipse, the moon is only partially in Earth’s shadow, and only part of it becomes red. Monday’s penumbral eclipse will be visible throughout the U.S.
