Why do solar eclipses happen only during a new moon?
Answers
GPT-4o mini
Solar eclipses happen only during a new moon because of the alignment of the Earth, Moon, and Sun. During a new moon, the Moon is positioned between the Earth and the Sun, allowing the Moon to block some or all of the Sun's light from reaching the Earth.
For a solar eclipse to occur, these three celestial bodies must be aligned in a straight line, which is why it is only during the new moon phase that a solar eclipse can take place. During this time, the Moon's shadow is cast on the Earth, creating either a total, partial, or annular solar eclipse, depending on the specific alignment and distances between them.
In contrast, during other moon phases, such as the full moon, the Moon is on the opposite side of the Earth from the Sun, and thus it cannot block the Sun's light. This is why solar eclipses are exclusively associated with the new moon phase.
