The Venus of reality bears little resemblance to the steamy, jungle-covered planet imagined by Ray Bradbury and Robert Heinlein, but it’s no less interesting: a hellish world, with an atmosphere of sulfuric acid and temperature in the mid-800’s, crisscrossed by fractures up to 100 meters wide. In the lecture “New Face of Venus,” planetary geologist Jim Zimbelman reveals what NASA’s Magellan probe found beneath the veil of the planet’s cloud cover. At 9:30 a.m. at the National Air & Space Museum’s Einstein Planetarium, 6th & Independence Ave. SW. FREE. (202) 357-2700. (Greg Kitsock)
