What Does the Sun Sound Like? [rerun]

Inspired by freeze-dried ice cream at Space Camp, podcast producer of 99% Invisible Avery Trufelman wonders what the sun really sounds like setting aside the hokey furnace effect shown in movies. Knowing that no sound waves can travel in the vacuum of space, fellow space camper and Completely Optional Knowledge host Andrew Norton finds a marvelous audible version of satellite data from sonification specialist Robert Alexander who trains heliophysicists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, to pick out subtle differences by listening to satellite data instead of looking at it. So get some astronaut ice cream and join in by pushing the “play” button.
