Examples for

Eclipses

An eclipse is an astronomical event where one object blocks, or occults, another object. The most notable eclipses are solar eclipses and lunar eclipses. Obtain information about both lunar and solar eclipses, in the past or future, using Wolfram|Alpha. In a solar eclipse, the Sun is blocked when the Moon moves in front of it from the point of view of an observer on Earth. In a lunar eclipse, the Moon moves into the Earth's shadow and is blocked from view, or at least is darkened significantly. Eclipses can be total or partial. Solar eclipses can also potentially be annular, where only a ring of the Sun is visible, or hybrid, where the eclipse may be annular or total depending on the time and location of observation.
