Is the sun covered completely by the moon?
Yes. That would occur when the eclipse occurs while the moon is near perigee. Closer to apogee the eclipse is not total, it is annular.
When the Moon's shadow hits earth or earths shadow hits the moon then what occurs?
it would be an ECLIPSE! ;p
When a person on the earth is observing a lunar eclipse which eclipse an astronaut on the moon facing the earth observe?
A solar eclipse. Earth would cover the Sun from his point of view.
What is the different of umbra and penumbra?
Umbra and penumbra when referred to the moon describes the shadow which is formed when light is blocked from the sun, by the moon. This shadow which falls on the Earth and has two distinct regions; a partially shadowed area which is the penumbra and the centre point a totally dark umbra. We on Earth looking skyward and watching the shadow pass as the Earth revolves would describe the penumbra as a partial eclipse and the umbra as a total eclipse.
What do you call it when the moon casts a shadow on the earth?
This is called a solar eclipse as the moon is blocking out the sun from your perspective on Earth. The actual shadow has two parts which both have their own names. The area that is the full shadow where you would witness a total solar eclipse is called the umbra. There is also a larger and less dark shadow that is cast around the umbra called the penumbra. In this area only a partial eclipse would be witnessed.It is a solar eclipse, or an eclipse of the sun. Only a small part of the earth's surface is darkened by the moon's shadow at any moment, and the shadow follows a path across the surface for as long as the earth, moon and sun are aligned closely enough.
In which part of a shadow would you need to be to observe a lunar eclipse?
The umbra.
Why can't you see the Moon's shadow except in an eclipse?
A solar eclipse occurs when the moon's shadow falls on Earth. At all other times the moon's shadow simply goes out into empty space; there is nothing to cast a shadow on. The only way to observe the moon's shadow at such a time would be to fly a spaceship into the shadow.
When a person on the Earth is observing a lunar eclipse an astronaut on the moon facing the Earth will observe an eclipse of what important star?
That person would observe an eclipse of the sun.
A person standing in the moon's what would see a particle solar eclipse?
In the Moon's shadow. Particularly, the "penumbra" which is the lighter partial shadow, rather than the "umbra", the darker total shadow area.
Where would you need to be on Earth to see a total solar eclipse?
On the surface, not underground... unless you would be sitting in front of a television monitor... Seriously, the size of the moon's shadow depends on how far away the moon is. Sometimes, when the moon's shadow falls on Earth there is no place where the moon seems to be blocking the whole sun. Then there is no total eclipse. It is a partial eclipse everywhere. To find out where to go to see the next total eclipse of the moon, (later than 24 Jan 12) just Google it.

Yes. That would occur when the eclipse occurs while the moon is near perigee. Closer to apogee the eclipse is not total, it is annular.
What is the definition of umbra?
The umbraUmbra comes from the Latin "shadow". It is the darkest part of a shadow. From within the umbra, the source of light is completely blocked by the object causing the shadow. This contrasts with the penumbra, where the light source is only partially blocked and there is only a partial shadow.

Is a lunar eclipse when the moon is between the earth and the sun?
no a lunar eclipse is when the earth's shadow is on the moon so the order would be: Sun Earth Moon an eclipse when the moon's shadow falls across earth is a solar eclipse
What is the part of a shadow that surrounds the darkest part?
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.
When the Moon's shadow hits earth or earths shadow hits the moon then what occurs?
it would be an ECLIPSE! ;p
What is the moon passing through the earths shadow?
That would be a lunar eclipse.
