The darkest part of the moon is called the Umbra. That is the darkest not the largest.
The dark shadow cast by the Earth on the Moon during a lunar eclipse is called the umbra. This is the central and darkest part of the shadow where the light from the Sun is completely blocked.
The shadow cast by the moon on Earth during a solar eclipse is called the umbra. This is the central, darkest part of the shadow. Surrounding the umbra is a lighter shadow called the penumbra, where only a partial eclipse is visible.
The Moon's shadow has two main parts: the umbra and the penumbra. The umbra is the innermost, darkest part of the shadow where the Sun is completely obscured by the Moon, resulting in a total solar eclipse. The penumbra is the outer, lighter part of the shadow where only a portion of the Sun is obscured, leading to a partial solar eclipse.
A lunar eclipse can occur during the night when the Earth passes between the Sun and the Moon, casting a shadow on the Moon. However, it is also possible to have a partial lunar eclipse during the day, depending on the position of the Moon and the Earth's shadow.
The darkest portion of the Moon's shadow during a total solar eclipse is called the umbra. It is the region where the Sun is completely blocked and only the Moon's shadow falls on Earth, creating the darkest point of the eclipse.

This is when the earth is between the moon and the sun, causing a shadow of the earth on the moon. It has to be really well lined up for this to happen, but they are fairly common.
The darkest, "total" shadow is called the "umbra", while the partial shadow is called the "penumbra", from the latin prefix "pen" meaning "almost".
There are two parts of a shadow: the UMBRA and the PENUMBRA. UMBRA is the inner darker part of a shadow. PENUBMRA is the outher lighter layer of a shadow. During a solar eclipse, the area on the planet that witnesses a complete total solar eclipse would be under the moon's shadow's UMBRA. The area that views a partial solar eclipse would be under the PENUMBRAL shadow.
