What is the dark inner shadow where total eclipses can be seen on earth?

"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?

How is a total eclipse created?
A lunar eclipse occurs when the earth passes between the sun and the moon. In other words, the moon is in the earth's shadow. A solar eclipse occurs when the moon comes between the earth and the sun. In other words, the earth is in the moon's shadow. The earth is much larger than the moon, so the moon's shadow is considerably smaller than the earth's. Total lunar eclipses are far more frequent and can be seen by everyone on earth with a view of the moon. A solar eclipse can only be seen by those within the narrow band of the moon's shadow.
What is the effect of umbra and penumbra on eclipses?
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.
What is the lighter side of a shadow called?
Penumbra. Total shadow is the UMBRA. Partial shadow is the PENUMBRA. These words usually refer to solar/lunar eclipses. However, they can refer elsewhere to shadows.
What happens if the moons shadow falls on the Earth?
In that case, a Solar Eclipse occurs. It can be a partial or total eclipse depending on the positions at the time of the eclipse. In total Solar Eclipses, the sun is completely blocked out for a short time in some parts of the world. Likewise, Earth's shadow falling on the Moon is known as a lunar eclipse.
What is the lunar ecplise?
A lunar eclipse occurs when the moon passes through the Earth's shadow. The moon passes behind the earth and prevents the sun's rays from striking the moon. There are three basic types of lunar eclipses: 1. Penumbral Lunar Eclipse - when the moon passes through the Earth's penumbral (outer) shadow. This type of eclipse is very subtle and difficult to notice. 2. Partial Lunar Eclipse - when part of the moon passes through the Earth's umbral (inner) shadow. This type of eclipse is easy to see. 3. Total Lunar Eclipse - then the entire moon passes through the Earth's umbral shadow. The moon turns a red hue. A lunar eclipse can only occur during a full moon when the Sun, Earth, and Moon are aligned with the Earth in the middle.
How many solar eclipses are there in 2 years?
In 2013 and 2014 there will be a total of four solar eclipses. When the moon casts a shadow over the Earth, and the moon is between the sun and Earth, there is a solar eclipse.
Name one type of eclipse?
There are lunar eclipses, in which the Moon goes into the Earth's shadow, and solar eclipses, in which the Earth goes into the Moon's shadow. Depending on how precise is the alignment of the Sun, Earth and Moon, the eclipse may be total, or if the alignment isn't perfect, a partial or penumbral eclipse can occur.
Is there ever going to be an Eclipse?
There are generally two lunar eclipses and two solar eclipses each year. Sometimes you will see two partial eclipses instead of one total eclipse; in 2011, there will be four partial solar eclipses, and no total or annular solar eclipses. Since lunar eclipses happen on the Moon, they are visible from the entire night half of the Earth. Solar eclipses, when the Moon's shadow hits the Earth, affect very small areas of the Earth, and so they seem to be more rare. The next total lunar eclipse will happen on December 21, 2010, and will be visible from any point in North America.
When does a Lunar eclipses happen?
A total lunar eclipse happens when the Earth blocks out the moon entirely from the sun.
How would solar eclipses be different if the Moon were twice as far from EarthWhy?
If the Moon were at twice its orbital distance, there would be no total solar eclipses, only annular ones. This is because the umbra, the complete shadow of the Moon, would not reach to the Earth. I would have to run the numbers to be certain, but I suspect that there would be no total lunar eclipses, either, for the same reason. However, you would probably be able to see the shadow of the Earth passing across the face of the Moon!
What occurs more often- a partial solar eclipse or total solar eclipse?
Partial 35.3%Annular 33.2%Total 26.7%Hybrid 4.8% As you can see from the table above, partial eclipses are most common, followed by annular eclipses. Total solar eclipses are barely more than one-quarter of the total. Total eclipses occur when the Moon is close enough to the Earth for the umbra, the cone of total shadow, to hit the Earth. Annular eclipses occur when the Moon is so far away that the umbra does not reach all the way to the Earth. "Hybrid" eclipses occur when the Moon crosses the dividing line between total and annular DURING the eclipse, so that the eclipse begins as annular and changes to total, or vice versa, during the eclipse.
Is earth the only planet that has eclipses?
Earth is the only known planet with a moon of the right size and distance to entirely block the light of the sun, producing a total solar eclipse. Partial solar eclipses (a moon passing between the sun and the planet it orbits) and lunar eclipses (a moon passing into the shadow of the planet it orbits) are commonplace and not limited to Earth.
Is it possible to have a total lunar eclipse when the moon and sun are both at their maximum distances?
No. If the Moon is close to apogee (the farthest distance from the Earth), then the Moon's umbra doesn't reach all the way to the Earth. (The umbra is the cone of total shadow. When the total shadow hits the Earth, we have a total eclipse.) So when the Moon is near apogee, we get annular, or "ring of fire", eclipses.
Why do you observe solar and lunar eclipses?
because of our location on earth so depending on where we are on earth you can see a total or partial solar and lunar eclipses
Is it true that the umbra is the inner part of the shadow?
Not precisely. The umbra is the TOTAL part of the shadow. In a total eclipse, where the eclipsing object is spherical, then the "inner" part of the shadow is the umbra, but in a partial eclipse, there IS NO umbra; just the "penumbra", the partial shadow.
What causes solar lunar eclipses?
A lunar eclipse occurs when the moon passes behind the earth so that the earth blocks the sun's rays from striking the moon. This can occur only when the Sun, Earth, and Moon are aligned exactly, or very closely so, with the Earth in the middle.A solar eclipse occurs when the Moon passes between the Sun and the Earth, and the Moon fully or partially covers the Sun as viewed from a location on EarthA solar eclipse is caused when the moon intercepts the Earth and sun, therefore we only see slight sunlight, if any.A lunar eclipse is caused when the Earth blocks the sunlight from the moon, making the moon "invisible" to us.A solar eclipse is caused when the moon comes between the earth and the sunA lunar eclipse is caused when the earth comes between the moon and the sun.Solar eclipses occur when the Moon is between the Sun and Earth, with the Moon's shadow falling on the Earth. Lunar eclipses occur when the Earth is between the Sun and the Moon, with the Earth's shadow falling on the Moon.a solar and lunar eclipse occurs when the sun, moon, and earth is in a straight line. in a solar eclipse, the order of the 3 is: the sun, the moon, and the earth. in a lunar eclipse, the order is: the sun, the earth, and then the moon. (a way 2 remember is lunar means "moon", and the moon comes last in a lunar eclipse)is causes it because the earth spins around the axis causing the lunar and solar eclipse ?Solar eclipses are caused by the moon's shadow when the moon's orbit makes it travel between the earth and the sun - total eclipses are caused by the umbra and partial eclipses by the penumbra of the shadow per se. Lunar eclipses are caused by the earth's shadow when its orbit takes it between the sun and the moon. Naturally, lunar eclipses can best be seen at night and solar eclipses during the day.Lunar eclipses occur when the Moon gets into Earth's shadow. Solar eclipses occur when the Moon gets in front of the Sun, obscuring it from our view.a solar eclipse is when the moon coves a part of the sun and a lunar eclipse is when the earth casts a shadow on the moon
Which eclipses occur when the tilt of the moon's orbit around the earth is tilted at zero to the earth's orbit?
This is when a Solar Eclipse occurs, the total eclipse happens when the moon's apparent size is bigger than the sun's and the moon blocks out nearly all of the sun's light - thus making stars appear.
