Question

So if the Moon's shadow is falling on the Earth during a solar eclipse, what phase of the moon must it be? (The moon is between the Earth and Sun.)

Answer 1

New moon

Step-by-step explanation:

A solar eclipse can only occur during New Moon (when the entire moon is covered in darkness and not visible from the earth's surface.) A total solar eclipse can be seen within the moon's dark inner shadow (called the umbra.) A partial solar eclipse can be observed within the earth's lighter outer shadow (called the penumbra).
