The umbra ans penumbra
A lunar eclipse is where the Earth comes between the moon and sun, so that light to the moon is blocked out by Earths shadow. A solar eclipse is where the moon comes between the sun and Earth, blocking out sunlight to the Earth.
The moon remains partly visible during a lunar eclipse because light is refracted round the earth by its atmosphere. A lunar eclipse is when the moon passes through earths shadow. A partial eclipse,is when only part of the moon is in earths shadow.Then the moon might look like something took a bite out of it.Unlike a partial eclipse,a total luna eclipse occurs whe the whole moon is in the earths shadow.The moon does not disappear during a lunar eclipse.Earths atmosphere bends and scatters some sunlight,allowing some of the suns rays to reach the moon.Lunar eclipses happen several times a year.
