A Solar Eclipse occurs when the Moon is positioned where?

A solar eclipse occurs when the Moon is positioned between the Earth and the Sun. In this alignment, the Moon blocks the Sun's light either partially or completely from reaching the Earth. This can happen during a new moon phase when the Moon is closest to the Earth in its orbit, allowing the shadow of the Moon to fall on the Earth and create the phenomenon of a solar eclipse. The direct alignment of the three celestial bodies is essential for a solar eclipse to occur, as this positioning allows for the shadow of the Moon to be cast onto the surface of the Earth, resulting in the brief darkening of the Sun for observers on Earth.
