Eclipses and Lunar Phases

The video explores the phenomena of solar and lunar eclipses, explaining how they occur due to the positions of the Earth, Moon, and Sun. It describes the phases of the Moon, from new to full, and the cycle duration. The video also discusses the far side of the Moon, its exploration through missions like Luna 3 and Apollo, and the Lunar Reconnaissance Orbiter's role in mapping the Moon. Observing these celestial patterns offers insights into the dynamic movements of celestial bodies.

What causes a solar eclipse to occur?

• The Earth moves between the Sun and the Moon.

• The Earth and Moon align side by side.

• The Sun moves between the Earth and the Moon.
