The moon will pass into the outer shadow of the Earth on Friday (May 5), creating an astronomical event called a penumbral eclipse. During the eclipse, skywatchers will see the moon darken but not completely disappear.
The penumbral lunar eclipse will begin at 11:15 EDT a.m. (1515 GMT) and will be visible from anywhere on the globe where the moon is over the horizon, including Antarctica, Asia, Russia, Oceania and Eastern and Central Africa. The event will peak at 1:24 p.m. EDT (1724 GMT) and will end at 3:32 p.m. EDT (1932 GMT) when the moon emerges from the Earth's shadow.
According to In the Sky (opens in new tab), the penumbral eclipse will not be visible at all from North America, South America or most of Europe as the moon will be below the horizon for the entire time Earth is in the shadow of the moon.
Like all lunar eclipses, penumbral eclipses occur as a result of Earth passing between the moon and the sun with the three bodies in a straight line. This results in the shadow of our planet falling on the moon's face as Earth blocks the light from the sun. This can lead to events that, unlike solar eclipses, can be subtle and difficult to observe.
A penumbral eclipse happens when the moon passes into the lighter outer region of the Earth's shadow which is called the penumbra. This is an area in which the Earth appears to cover part of the sun's disk but not all of it. This means when the moon is within the penumbra, it receives less light from the sun and is dimmed but still remains somewhat illuminated.

The resulting effect can be barely perceptible and is sometimes only visible in carefully-controlled photographs or by people with extremely acute eyesight. However, sometimes there are rare events in which the entire lunar face moves into the penumbra. These lunar eclipses cause a dimming that is more extreme and can be seen more easily by the unaided eye. These events are called total penumbral eclipses and they are rare because once the moon has fully entered the penumbra, it is highly likely that at least part of it will reach the umbra, the darker inner part of the Earth's shadow. This results in a partial lunar eclipse.
The last time a penumbral eclipse was visible from the contiguous U.S. was on Nov. 30. 2020, and the next time such an event will be visible from this region of the globe will be on March 25, 2024.
If you hope to catch a look at the features of the moon close-up during an eclipse or any other time, our guides to the best telescopes and best binoculars are a great place to start.
If you live in the path of the eclipse and want to take photos of it, be sure not to miss our guide on how to photograph a lunar eclipse.
