Total Solar Eclipse DEC. 4, 2021

Описание: A solar eclipse happens when the Moon moves between the Sun and Earth, casting a shadow on Earth, fully or partially blocking the Sun’s light in some areas. For a total solar eclipse to take place, the Sun, Moon, and Earth must be in a direct line. People located in the center of the Moon’s shadow when it hits Earth will see a total eclipse. The sky becomes very dark, as if it were dawn or dusk. Weather permitting, people in the path of a total solar eclipse can see the Sun’s corona, the outer atmosphere, which is otherwise usually obscured by the bright face of the Sun.
