In a world first, the sounds of Mars and Venus are revealed as part of a planetarium show in Hampshire this Easter.

Despite many years of space exploration, we have no evidence of the sound of other planets. While most planetary probes have focused on imaging with cameras and radar and a couple have carried microphones, none of them successfully listened to the sound of another world.

Now, a team from the University of Southampton, led by Professor Tim Leighton, has the answer. Using the tools and techniques of physics and mathematics, they created the natural sounds of other worlds, from lightning on Venus to whirlwinds on Mars and ice volcanoes on Saturn’s moon, Titan. In addition to these natural sounds, they have modelled the effects of different atmospheres, pressures and temperatures on the human voice on Mars, Venus and Titan (Saturn’s largest moon). They have developed unique software to transform the sound of a voice on earth to one that’s literally ‘out of this world’.
