The sound of space: Scientists reveal 'music' made by stars
It was said that in space noone can hear you scream, but scientists have managed to record and listen to the sound of three stars similar to our Sun. Outerspace is not a total vacuum but is extremely diffuse with only around one particle per cubic centimetre. Noise can therefore travel from distant galaxies but would be inaudible to our ears without extra help.A team used light curves collected over 60 days from France's Corot space telescope to pick up the celestial sound, which has given them vital information about processes deep within the cosmic bodies.
