"Earlier this month, the most technologically-advanced digital planetarium in the world opened in San Francisco's California Academy of Sciences. The new Morrison Planetarium's 75-foot screen replaces the traditional Zeiss projector with an array of 6 high-resolution DLP projectors arrayed around the edge of the theater, which are powered by three very different, but interesting computing clusters.

The three clusters allow for projection of traditional planetarium shows, playback of ultra-high resolution movies, and display of anything from current atmospheric conditions on Earth to a (greatly accelerated) trip to the farthest reaches of the universe, all rendered in real-time on an 8800 sq. ft. dome.

Maximum PC went on a behind the scenes tour with the engineers who built the systems that do everything from run the planetarium lights to the sound systems to the tech behind the screen to show you how it works and what it's like to drive, well ... the universe."
