For centuries, humanity has wondered whether we are alone in the universe. With the discovery in 1995 of the first planet orbiting another star, we now know that planets are not unique to our own Solar System. In fact, these “extrasolar” planets now appear to be quite common. In the S.B. Museum of Natural History’s newest planetarium show, Wonders of the Winter Sky, you can an immersive tour of the heavenly bodies-Cassiopeia, Cephas, Andromeda, and several worlds that just might fit the “Earth-like” conditions humans are looking for. From water worlds to molten landscapes, inhabitable moons to planets with multiple suns, these exotic worlds aren’t just science fiction anymore! Come watch at 1 p.m. on Saturday, January 17, at the S.B. Museum of Natural History (2559 Puesta del Sol Rd.). Admission is $4. Call 682-4711 for more info.
