The light outer part of a shadow is called the "penumbra." It is the region where some light is obstructed, but not completely blocked, resulting in a gradient of light and shadow. This area surrounds the darker central part of the shadow, known as the "umbra," where the light source is entirely blocked. The penumbra creates a transitional zone between light and shadow.

What is the lighter outer part of the shadow during an eclipse?
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.

The penumbra is the outer, lighter part where only a portion of the light is obscured, leading to a partial eclipse.
What is a broader outer part called in an eclipse?
The broader outer part of an eclipse is called the "corona" during a solar eclipse, which refers to the outer atmosphere of the Sun that becomes visible when the Moon completely covers the Sun. In the context of a lunar eclipse, the broader outer shadow is referred to as the "penumbra," where only a portion of the light is blocked.
What are the different types of shadows?
There are three main types of shadows: umbra, penumbra, and antumbra. The umbra is the darkest part of a shadow, where the light source is completely blocked; the penumbra is the lighter, outer part where the light is partially obscured; and the antumbra occurs when the light source appears larger than the object casting the shadow, creating a lighter shadow that may have a halo effect. These types can vary based on the position of the light source and the object in relation to it.
What are the two regions of shadow?
The umbra is the central, darkest part of a shadow where no direct light reaches, while the penumbra is the outer region where some light is still visible around the edges of the shadow.

What are the Moon's umbra and penumbra?

It can best be seen when the viewer is beyond the focal point of the umbra, but in line with it.
