Joy Guo If you’ve ever dreamt of venturing through the vast frontier of outer space to see the moon, the stars, and all the known universe, you’re in luck; the UW department of astronomy’s mobile planetarium is a 20-foot wide, inflatable, walk-in dome that immerses audiences in laptop-projected galaxies. The mobile planetarium is designed to be easily brought to audiences who cannot visit the UW’s brick-and-mortar planetarium in the Physics-Astronomy Building on campus.
