Visit the Student Astronomical Society's Astronomy Open Houses to learn about astronomy, physics, and optics! This Friday is a special event, Statewide Astronomy Night, and we will be holding an extra long open house this week. Join the Bentley Historical Library, UM Museum of Natural History, and Department of Astronomy for more cool events, including a lecture on dark matter, tours of the observatory hosting the oldest US-made lens still in use, and more!Open houses are run by members of the Student Astronomical Society and are free, as well as open to all ages. We always have planetarium shows, science demos, and observatory tours. When the weather allows it, we have observing on the roof of Angell Hall, where we have a 0.4 M telescope in our observatory dome, plus multiple smaller telescopes and binoculars. See our website, umichsas.com, for more information!
