penumbra

Vocabulary Word

Definition

Penumbra refers to the partly shaded area around the shadow of an object. It's less dark than the main shadow. For example, during a solar eclipse, the area experiencing penumbra sees a partial, not total, eclipse.

Examples in Different Contexts

In astronomy, 'penumbra' plays a key role during lunar and solar eclipses. An astronomer might explain, 'During the lunar eclipse, you can see the moon passing through the Earth's penumbra before it enters the umbra.'
