On Aug. 21, 2017, American skywatchers will be treated to a rare and spectacular celestial show — the first total solar eclipse visible from the continental United States in nearly four decades. Next year’s “Great American Total Solar Eclipse” will darken skies all the way from Oregon to South Carolina along a stretch of land about 70 miles (113 kilometers) wide. “People who descend upon this “path of totality” for the big event are in for an unforgettable experience,” said eclipse expert Jay Pasacho, an astronomer at Williams College in Massachusetts. Wherever you are you can catch it right here on Slooh.
Solar eclipses occur when the Moon’s orbit passes directly between the Earth and the Sun, obscuring part or all of the solar disk. ere are several types of solar eclipses, including annular and partial eclipses (when the Moon only obscures a portion of the Sun), and the incredible sight of a Total Solar Eclipse. While the Sun is actually about 400 times larger in diameter than the Moon, the Moon is also about 400 times closer than the Sun. Therefore, the Sun and the Moon appear to be about the same size in our sky, and that’s why they’re able to right on top of each other.
