Ever wondered what natural sounds you would hear on another planet? Although some spacecraft have carried microphones, sound has never been reliably recorded in an alien atmosphere. But now, thanks to simulations created by Tim Leighton from the University of Southampton, UK, and his team, you can hear what Mars and Venus would sound like.
In this video, you can listen to the recreated sound of a waterfall, thunder and a human voice on different planets and on Titan. Leighton used physics models to produce the sound of thunder and waterfalls in the different atmospheres, whereas the voice was morphed fromrecordings. "On Venus, the atmosphere is thick and soupy so vocal chords that would flutter lightly on Earth would vibrate more slowly," says Leighton. "As a result, the pitch of your voice drops."
