Just over two weeks after its dark silhouette crossed in front of the sun for parts of the Indian Ocean, extreme Western Australia, New Guinea and the Pacific Ocean, it is now the moon's turn to undergo an eclipse.
On May 5, the moon almost drops completely below the Earth's shadow, in the process sampling only the shadow's outermost part — called the penumbra — which is not only pale but grades to even paler outward, away from the dark, central part of the shadow, known as the umbra. As such, this event is called a penumbral lunar eclipse.
The penumbral lunar eclipse will begin at 11:13 a.m. EDT (1513 GMT) on Friday (May 5) and will peak at 1:24 p.m. EDT (1724 GMT). The eclipse will end at 3:31 p.m. EDT (1932 GMT) when the moon emerges from the Earth's shadow.
