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.
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 total lunar eclipse can occur during a full moon phase. During this phenomenon, the Earth is positioned directly between the Sun and the Moon, casting a shadow on the Moon and creating the eclipse.
The thin red rim around the Sun during a total solar eclipse is called the solar chromosphere. It is the lower part of the Sun's atmosphere and is visible during a total solar eclipse when the Moon fully covers the Sun's bright disk, allowing the chromosphere to be seen.
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.
Yes, it gets dark during a total solar eclipse.
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.

A total lunar eclipse can occur during a full moon phase. During this phenomenon, the Earth is positioned directly between the Sun and the Moon, casting a shadow on the Moon and creating the eclipse.
This can only happen at 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.
