We know how many times Britney has been married. We know where Angelina Jolie's tattoos are. We even know what Paris looks like having sex. But how much do we know about the other stars—you know, the ones in the sky?

On a recent visit, one UCLA student compared the planetarium to Disney World's Epcot Center, saying it was, "like, an educational ride." The one-hour show dedicates about 40 minutes to a factoid-laden sky show, then spends about 20 minutes on one specific topic. On clear nights after the sky show, visitors (who are usually UCLA students racking up extra-credit points for class) are invited to a telescope viewing. Stargazers can see Saturn, our moon, Jupiter and its moons through a 14-, 16- or 24-inch reflecting telescope. Free public planetarium shows and telescope viewings are held every Wednesday night; during the summer, the free shows are held on the second and fourth Wednesdays of the month. Planetarium shows start promptly at 8pm, while telescope viewing begins at 9pm; if you're late, you will be locked out of the 50-seater planetarium, so allow at least a half hour for parking and finding the Mathematical Sciences building on campus. During the fall, winter and spring, both shows are scheduled an hour earlier. The planetarium also hosts school groups (free of charge) and corporate events (which require a small fee). Events can be booked at planet@astro.ucla.edu. Watch out, Space Mountain.—Mai Dinh
