Lunar eclipses are captivating events where the Earth casts a shadow on the Moon, with types ranging from penumbral to total eclipses. They reveal the Earth's umbra and penumbra, and during a total eclipse, the Moon can appear red due to atmospheric filtering of sunlight. These eclipses have deep cultural roots and are predictable thanks to cycles like the Saros.
