When one celestial body moves into the path of another, blocking its light, the event is known as an eclipse. There are two types of eclipses. A solar eclipse is when the moon
blocks the sun. A lunar eclipse is when the Earth blocks the sun's light from reaching the
moon. Because objects in space travel according to a pattern, solar and lunar eclipses are
predictable. So you can find out when the next eclipse is happening and whether you can see
if from where you live.
