Learn how to find the planets and constellations visible in York's January night sky during three shows presented by the York County Astronomical Society.

Join Jackie and Michelle, two teenage girls, as they hear about the Christian and Jewish religious events during this time of year. This program includes a look at some of the solstice customs of some of the peoples of central Africa, China, Native Americans, the Inuit and the Incas to name a few.

* "StarWatch" viewers can become star watchers by exploring the current night sky, locating visible constellations, and enjoying some sky lore.
