What causes an eclipse?

An eclipse occurs when one celestial body passes in front of another, blocking its light. A solar eclipse happens when the Moon passes between the Earth and the Sun, casting a shadow on Earth and blocking the Sun’s light. A lunar eclipse occurs when the Earth passes between the Sun and the Moon, causing the Earth’s shadow to fall on the Moon, darkening it. Eclipses are rare events that occur when the Earth, Sun, and Moon align in specific ways, and they provide valuable opportunities for scientific study.
