(meteorobs) Super Sound Of Shooting Stars




Super sound of shooting stars
From BBC Science reporter Dr Chris Riley in San Francisco

A Croatian astronomer thinks he has cracked a meteor mystery that has
baffled the scientific world for over two centuries.

He has managed to record what he believes are the illusive, instantaneous
sounds made by shooting stars as they crash through the Earth's upper
atmosphere.

The extraordinary thing about these noises is that the observer on the
ground hears them at the same time as the meteor appears overhead. On the
face of it, this would seem impossible because it would require the noises
to break the sound barrier!
