Lunar Eclipse

Here is a small article about Lunar Eclipse.
Lunar Eclipse means, Earth coming in between Sun and the Moon for a small duration of time and hence creating a shadow on Moon to make it hidden. At one moment of time, the Moon completely gets covered by the shadow of Earth which is the height of the event (Eclipse). During the process of Eclipse, the Moon may be completely covered or partially covered by the shadow of Earth. Based on the visibility of Moon, the Lunar Eclipse was differentiated as 2 types: Umbra and Penumbra.
It is the darkest part of Shadow during which the light source is completely blocked by occluding body (earth). This makes, the observer to experience a complete/dark eclipse.
"Penu" is a Latin word which means "Almost, nearly" and "umbra" means: shadow. As the name itself indicates, only a portion of the light source is obscured by the occluding body. Hence user experiences a partial eclipse.
