Editor's note: The Great American Solar Eclipse was on Aug. 21. It swept across the continental United States from Oregon to Georgia. See our full coverage. Another total solar eclipse will be seen across the United States in 2024. A solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth. A solar eclipse can only take place at the phase of new moon, when the moon passes directly between the sun and Earth and its shadows fall upon Earthâs surface.
