total lunar eclipse

A total lunar eclipse occurs when Earth passes directly between the Sun and the Moon, blocking sunlight from reaching the Moon. During this event, the Earth's shadow covers the Moon completely. The Moon takes on a reddish hue because sunlight passing through Earth's atmosphere is bent and filtered, scattering the shorter blue and green wavelengths while allowing the longer red wavelengths to illuminate the Moon. This creates a striking, copper-colored appearance. Total lunar eclipses can last several hours and are safe to view with the naked eye, providing a stunning natural spectacle without any special equipment.
