What is and a eclipse in which the moon appears darkened as it passes into the earths shadow?

A lunar eclipse occurs when the Earth comes between the Sun and the Moon, causing the Earth's shadow to cover the Moon. During this event, the Moon can appear darkened or take on a reddish hue, often referred to as a "blood moon." This phenomenon happens only during a full moon and can be seen from anywhere on the night side of the Earth. Lunar eclipses can last for several hours, depending on the alignment of the celestial bodies.
