Earth Science
A lunar eclipse occurs when the Earth passes directly between the Sun and the Moon, causing the Earth's shadow to fall on the Moon. This celestial event can only take place during a full moon and can result in a striking visual phenomenon, often turning the Moon a reddish color due to Rayleigh scattering of sunlight through the Earth's atmosphere. Lunar eclipses are significant for understanding the geometry of Earth-Moon-Sun relationships and the effects of these alignments on visibility and astronomical observation.
