Ep. 160: Eclipses

October 19th, 2009

Episode 192 of 459 episodes

Every now and then, the Moon destroys the Sun. Okay, not destroys, covers. Well, not really covers, but from here on Earth, sitting inside the shadow of the Moon, that's what it sure looks like. These events are called eclipses, or more precisely, transits and occultations. They occur whenever one object passes in front of another from a 3rd perspective. They're beautiful and exciting, and deliver a tremendous amount of science as well.
