The lighter outer part of a shadow during an eclipse is called the penumbra. In this region, only a portion of the light source is obscured, allowing some light to reach the area, resulting in a partial shadow. This contrasts with the darker central area known as the umbra, where the light source is completely blocked. As a result, observers in the penumbra experience a partial eclipse.
There are two main shadows that Earth projects; one is called the 'umbra', which is the complete shadow where all direct light is blocked out, the other is the 'penumbra', which is a partial shadow. The effect is similar to standing in front of a light source and seeing both a dark shadow in the middle (the umbra) and a lighter shadow on the outer edge (the penumbra). During this eclipse the Moon will pass through both shadows.
