SOLAR SYSTEM

Detailed explanation-1: -During an eclipse the Earth blocks sunlight from reaching the Moon. Earth creates two shadows: the outer, pale shadow called the penumbra, and the dark, inner shadow called the umbra. The eclipse is noticeable once the Moon enters the umbra.

Detailed explanation-2: -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.

Detailed explanation-3: -The umbra, penumbra and antumbra are three distinct parts of a shadow, created by any light source after impinging on an opaque object.

Detailed explanation-4: -A shadow is the dark shape made when something blocks light from a light source like the sun, a flashlight, or campfire.
