A penumbral eclipse is much more subtle than a total or even partial eclipse, as only the lighter outer shadow of the Earth (called the penumbra) darkens the moon.
During a penumbral lunar eclipse, the moon gradually grows a little darker until the maximum eclipse, after which it gradually lightens again.Unlike during a total or partial eclipse, the face of the moon won’t darken completely, and some people may not be able to notice a difference at all.
A total lunar eclipse is set to take place May 26, 2021, in the wee hours of the morning, and a partial lunar eclipse from Nov.
A solar eclipse always occurs about two weeks before or after a lunar eclipse, said Jim Todd, director of space science education at OMSI, but this time most of the world will miss out: The next total solar eclipse will be on Dec.
