Space Rocks celebrates astronomy and music at London's O2

Space Rocks, an event celebrating astronomy and music, kicks off this Sunday. The twinned nature of the disciplines it celebrates stretch back millennia

Somehow music and astronomy seem to go together. The association was made in the 6th century BC by the philosopher Pythagoras, who suggested each planet made a different sound and that together these notes made up the musica universalis, the harmony of the spheres.

Although we no longer think of the planets as singing, the fact that there is mathematical "harmony" in both music and the laws of physics means they remain partners.
