In this SMAP, six undergraduate researchers present the ins and outs of using Stellarium, the web-based application that turns your computer or tablet into your own personal planetarium. We show you how to locate your own local night sky, seek out deep sky objects, interpret constellations and the zodiac, and go back in time and forward into the future to predict future events.

We also invite our students to participate in doing the experiment originally performed by Eratosthenes over 2300 years ago in ancient Egypt. Armed with nothing more than shadows cast by the noon-day sun at two locations, you too can can calculate the circumference of the Earth. You provide your own shadow measurements, and we will provide the second set for your calculations. Join us and see how it's done.
