There's something mesmerizing about sitting in a darkened planetarium, gazing at the domed ceiling, and watching the spectacle unfold above you. Burke Baker grants just such an experience, courtesy of feature presentations that riff on space travel and exploration, the history of the moon, the evolution of our own planet, constellations, and the possibilities of extraterrestrial life. Other shows let visitors take a microscopic journey through the body or groove to Pink Floyd's "Dark Side of the Moon" through lights and music.
