There's free star shows every wednesday & friday at 7 pm. And on the weekends, there are full dome science/space shows for a small fee... One of their most popular is the physics of Star Wars. The students who work here make a lot of their own shows, so topics have a wide range of topics!
The free shows are generally an hour long, half being an educational lecture on something related to astronomy while the second half is a planetarium star projected tour of the night sky. These are live lectures and star programs, not prerecorded. The lecturers map out the constellations with a lazer pointer. If you're wanting badly to see a certain constellation, come early and chat with one of the students! They are really good at answering questions & are great teachers.
