I think it's penumbra. It's the area around something.


Can you tell the difference between a lunar eclipse and the normal phrases of the moon?

Definitely. First as the Moon passes through the Prenumbra of the Earth it will darken. Then as it goes through the Umbra it will become a copperish red.


What is the Earth's prenumbra?

There is no such thing as 'prenumbra'. I think you mean 'penumbra'. When there is a solar eclipse, the Moon's shadow only falls on a narrow part of the Earth, its track. This is the point on Earth of totality, and is named the 'Umbra'. Outside the track of of totality, there is a region on either side of the track, which is in partial shadow; a partial eclipse as seen from the Earth. This partial shadow is properly named the 'Penumbra'.


What does it mean to say that the right to privacy falls within the prenumbra of a specific constitutional protection?

The US Constitution listed a set of un-enumerated rights that were thought to be so basic that they did not need to be listed as other rights were. These rights are often called penumbra's which means Obscure, but in law means implied. For instance, many claim "Free Speech" based on the First Amendment; while the First Amendment gives no right of "Free Speech" - the right of free speech to any individual is implied.


Why does half of earth experience night when the other half of earth is experiencing day?

The Sun is a single source of light. Therefore it can only shine its light on one side of the Earth at a time. The other side is then obviously dark. Try shining a torch on a tennis ball in a dark room. One side will by light and the other side will be dark.Apart from the dark and light part,there is also a part that is fairly dark known as the prenumbra. dark-umbra fairly dark-prenumbra
