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.
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 outer portion of the shadow is called the "penumbra".
An eclipse shadow consists of two main parts: the umbra and the penumbra. The umbra is the inner, darker part of the shadow where the light from the source (like the Sun) is completely blocked, resulting in a total eclipse. The penumbra is the outer, lighter part where only a portion of the light is obscured, leading to a partial eclipse.
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.
The two parts of the moon's shadow are the umbra, which is the dark central region where light is completely blocked, and the penumbra, which is the lighter outer region where only partial light is blocked.
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.
Umbra is latin for shadow. It's often used for the central part of the shadow of the moon during an eclipse. The outer part of the shadow, or penumbra, still receives some light.
The Moon's umbra is the central, darkest part of its shadow during a lunar eclipse where the Sun is completely blocked. The penumbra is the outer, lighter part of the shadow where only a portion of the Sun is obscured, creating a partial eclipse.

penumbra
The darkest part of a shadow is called the "umbra" The lighter part of a shadow is called the "penumbra" An "antumbra" is the area of light which surrounds the object creating a shadow, as in a "ring of fire" eclipse (like the recent one in May, 2012). It can best be seen when the viewer is beyond the focal point of the umbra, but in line with it.
