Detailed explanation-1: -During a solar eclipse, the Moon casts a shadow on Earth, and blocks or partially blocks our view of the Sun.
Detailed explanation-2: -During a total lunar eclipse, the entire Moon enters the umbra. A partial lunar eclipse occurs when the umbra covers only part of the Moon’s surface. A penumbral lunar eclipse occurs when the Moon enters the Earth’s penumbra.
Detailed explanation-3: -During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. There are two kinds of lunar eclipses: A total lunar eclipse occurs when the Moon and Sun are on opposite sides of Earth. A partial lunar eclipse happens when only part of Earth’s shadow covers the Moon.
Detailed explanation-4: -Because the Moon can be completely immersed in the Earth’s umbra during a total lunar eclipse, these eclipses can be seen from the entire night-time hemisphere. This is in contrast to total solar eclipses as we’ll see below.
Detailed explanation-5: -During a solar eclipse, the Moon actually casts two shadows toward Earth. One shadow is called the umbra which becomes smaller as it reaches the Earth. This is the dark center of the Moon’s shadow. The second shadow is called the penumbra.
