The "umbra" is the dark area of complete shadow. Around it is the "penumbra", which is partial shadow.
Penumbra or prenumbria or something like that. it is mentioned or implied in one of the songs of Columbia College ( Rah Lion Rah).
I believe it is called the Penumbra or Prenumbria, rhymes with Columbia and is used in one of their football songs.
The darkest part of the moon is called the Umbra. That is the darkest not the largest.
"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?

During a total solar eclipse, the umbra or darkest part of the moon's shadow creates darkness on a small section of the Earth's surface. The penumbra is a part of the moons shadow that is more wide spread and not nearly as dark.
No, the umbra is the darkest part, the area of maximum eclipse (which moves as the Earth turns).The area of partial eclipse is called the penumbra.

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.
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.
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.
"Umbra" means "shadow"; specifically the darkest part of the shadow of a planet or moon during an eclipse.
"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 darkest, "total" shadow is called the "umbra", while the partial shadow is called the "penumbra", from the latin prefix "pen" meaning "almost".
