Mysteries of the Cosmos

We've come a long way since the days when people thought the Sun revolved around the Earth, not the other way around!  But why did people think that, anyway, and what changed their minds?  Join us to learn how our current understanding of the solar system evolved, from the early Earth-centered models, to how the planets got their names, to the recent demotion of Pluto from the planetary clubhouse.

Program is free and open to the public.
