"Umbra" is correct. However, another way to look at it is that the darkest part of the Earth's shadow is midnight, for what is night but the shadow of the Earth?
The outer portion of the shadow is called the "penumbra".
The umbra in a shadow is the portion where light from a source is completely blocked. This is in the middle of the shadow. The area around this, where light from part, but not all of the source shines is called the penumbra. In the shadow cast by the moon in an eclipse, the penumbra is the partial shadow that occurs before the total eclipse, and the umbra is the 'total eclipse' portion
No, light is a form of energy and the shadow is the place where there is absence of light.
penumbra
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.
yes
If the light source is fairly large, it will create a total shadow, when the entire light source is blocked, and partial shadow where only part of the light source is blocked. The "umbra" is the area of total shadow, while the "penumbra" is the area of partial shadow.
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.

I think you are asking what is the lighter part of the Earth's shadow on the Moon that surrounds the darkest part. The penumbra is this lighter part of the shadow. The darkest part is the umbra.
