Listen to the “sound” of a star. It’s rather musical.

About 6,500 light years away, there’s a star known as RS Puppis, a Cepheid variable star that’s rather cool. The Hubble Space Telescope took a picture of it and the light was “sonified.” A sci-art project called SYSTEM Sounds took the data from the light emitted by Puppis, It took the light from the centre of the star and assigned it pitch. Volume came from the brightness of the star (the key thing about Cepheids is that they brighten and dim on a consistent basis.)

This was the result. (A deeper dive can be found here.)
