The sound of a black hole

A few months ago, a friend played me some remarkable recordings made by scientists at the Jodrell Bank Observatory, who had captured and made audible the "sound" of stars. I just discovered that these are available, with lots more information about how the recordings were made, on a recent edition of the observatory's JodCast:

Particularly mesmerising is the sound of material falling into a black hole (just after 23 minutes in on the podcast), which someone described as "God playing the bongos"!

For anyone interested in learning about astronomy, the visitors centre at Jodrell Bank and their online materials are an amazing resource.
