lunar eclipses

A lunar eclipse occurs when the Earth passes between the Sun and the Moon, casting a shadow on the Moon. This alignment can only happen during a full moon. There are three types of lunar eclipses: total, where the entire Moon is darkened; partial, where only a part of the Moon enters the shadow; and penumbral, where the Moon passes through the Earth's outer shadow, causing a subtle shading. Lunar eclipses are safe to view with the naked eye and can appear dramatically red, often referred to as “Blood Moon,” due to the scattering of sunlight in Earth’s atmosphere.
