A solar eclipse is one of the most dazzling celestial phenomena that you can experience from Earth. It occurs when Earth, the moon and sun are aligned on the same plane, with the moon passing in front of the sun to cast a shadow on the planet below.
During a total solar eclipse, the moon completely covers the sun, which results in a period of "totality," when the moon completely blocks the light from the sun. This causes evening-like darkness during the daytime, as the center of the moon's dark shadow falls over Earth. Viewers do not experience totality during a partial solar eclipse, when the moon only blocks a portion of the sun's disk.
