Wheel of Stars

by admin on January 18, 2010

Data visualization specialist Jim Bumgardner has created a sidereal time clock called the Wheel of Stars which depicts the night sky as a music box. Based on data from the ESA’s Hipparcos satellite, the wheel revolves around Polaris, and as stars cross the line between zero and 180 degrees, they sound off as chimes, based on their BV measurement and magnitude. Moving as fast as the Earth spins, it takes 24 hours to complete a full circle. Further fun with math, music, and circles can be enjoyed with his Whitney Music Box.
