Scientists used that data to calculate the speed of sound on the red planet and describe its soundscape. Percy has primarily heard the whoosh of wind and the noises made by its own machinery.

The upper limit on the speed of sound in solids and liquids depends on just two dimensionless quantities – the fine structure constant and the proton-to-electron mass ratio. That is the surprising ...

When we talk about the speed of sound, we usually mean how fast it moves through air. But it can travel much faster through other media, and now scientists at the University of Cambridge and Queen ...

An MIT engineer has a radical idea for determining just how strong a hurricane is: Analyze the sound of its roar, recorded by hydrophones 800 meters under the surface, to calculate the speed of ...

Bats have an internal sense of the speed of sound that they use to calculate the distance to perches or prey with echolocation, and it seems to be something they don’t have to learn ...
