On Aug. 21, 2017, the United States was treated to a rare celestial performance: a total solar eclipse, in which the Earth passed directly between the moon and the sun. Here's Live Science's coverage of the spectacular event.
As Earthlings, we have the privilege of ooohing and aaahing at total solar eclipses, those celestial events in which the moon blocks the sun's light from hitting our planet. But is Earth the only world in our solar system that experiences this phenomenon?
During the total solar eclipse on Aug. 21, skywatchers will direct most of their attention to the sun, but don't forget about the moon: Its slow progress away from Earth means these celestial events won't keep happening forever.
