The word "umbra" means "total shadow", wile the word "penumbra" refers to a partial shadow.
So when the Moon enters the Earth's shadow in a total lunar eclipse, it passes through the penumbra, in which part of the sunlight reaching the Earth is blocked, and goes into the umbra, where no sunlight can directly strike the Moon.
Answer
This is when the entire face of the moon is within the earth's umbra, or full shadow. No part of the moon is directly illuminated by sunlight.
A solar eclipse can only occur at New Moon.
can be seen by everyone on the nighttime side of Earth
The Earth moves between the Sun and the Moon.
A solar eclipse can only happen at the time of New Moon.
It has to be in new moon.
Full Moon
It is a new Moon. For a solar eclipse, the moon has to be between Earth and the Sun. We get a total lunar eclipse when Earth is between the Sun and the Moon. The Moon would have to be full for it to be eclipsed.
A lunar eclipse is possible only at the time of Full Moon. A solar eclipse is possible only at the time of new Moon.
There were no total solar eclipses during 2007. There was one total lunar eclipse, one partial lunar eclipse, and two partial solar eclipses.
The total phase of a solar eclipse can never last longer than 7 minutes and 29 seconds. MindOfTheLion: But why can't it be? If it occurs during a school day do they stop school to check it out?
A solar eclipse may be partial, total, or annular.
Then the total phase of the eclipse would last longer. Also, it is more likely that there is a total phase at all.
The total phase of a total solar eclipse is never more than 7 minutes 29 seconds, and you would need to be exactly ON the midpoint of the eclipse track to get that.
It is a new Moon. For a solar eclipse, the moon has to be between Earth and the Sun. We get a total lunar eclipse when Earth is between the Sun and the Moon. The Moon would have to be full for it to be eclipsed.
Sometimes, during a total solar eclipse, the corona of sun is visible to our eyes.
During a total solar eclipse, at one point it will be almost completely dark.
You can see the corona during a total solar eclipse
This can only happen at new moon.
A lunar eclipse is possible only at the time of Full Moon. A solar eclipse is possible only at the time of new Moon.
Any degree of solar eclipse can only occur within a few hours of the instant of New Moon.
-- During a partial solar eclipse, part of the sun is obscured from our view (by the moon) and the rest of it is still there. -- During a total solar eclipse, the entire disk of the sun is obscured from our view (by the moon).
Solar eclipse (total or otherwise): at new moon. Lunar eclipse (total or otherwise): at full moon. -- Immediately after a Solar eclipse you get a new crescent moon appearing in the sky. Obviously therefore the eclipse happens at the point when the side of the moon that faces us is in total shadow - indeed during the eclipse we are covered by that shadow. -- Immediately after a lunar eclipse, as soon as the moon moves out of the shadow, it is full.
There were no total solar eclipses during 2007. There was one total lunar eclipse, one partial lunar eclipse, and two partial solar eclipses.
