partial lunar eclipse

A partial lunar eclipse occurs when the Earth partially blocks sunlight from reaching the Moon. As the Earth moves between the Sun and the Moon, it casts a shadow. During a partial eclipse, only a portion of the Moon passes through Earth's dark central shadow (the umbra), causing that area to appear darker or tinted. The rest of the Moon remains illuminated, so viewers see a part of the Moon in shadow while the rest remains bright. This event offers a striking visual contrast and is a natural result of the alignments within the Earth-Moon-Sun system.
