Having spent RMB 300 million on a new building, the once-retro planetarium now boasts state-of-the-art facilities. The SGI Digital Universe Theater takes patrons on a tour of the cosmos with six Carl Zeiss laser projectors that simulate the movement of stars and constellations. You can also travel through time in the 4-D theater, where you’ll strap on a pair of goggles and watch a multi-dimensional film about the creation of the solar system and evolution of life on earth, replete with snarling T-rexes and saber-toothed tigers. Where does the fourth dimension come from? We don’t want to spoil the surprise but the experience terrified our three-year olds. Other draws include the 3-D space shuttle simulator and a cool exhibit about the sun.
