Heyer develops “Milky Way Blues” to “hear” motions of galaxy

Mark Heyer, Astronomy, has collaborated with UCSB postdoctoral fellow Greg Salvesen to produce a piece of music called “Milky Way Blues” based on astronomical data about our galaxy. For the composition, Heyer developed an algorithm that transforms astronomical data about galactic gases into musical notes. “This musical expression lets you ‘hear’ the motions of our Milky Way galaxy,” he says. “The notes primarily reflect the velocities of the gas rotating around the center of our galaxy.” The result was featured in Tech Times, Outerplaces, and Newsweek.
