Our Universe Is Not Silent. Although space is a vacuum, that does not mean there is no sound in it. Sound does exist in space in the form of electromagnetic vibrations. NASA recorded all planet sounds from space with the help of spacecrafts in the form of electromagnetic vibration and converted into the audible range of human ear (20-20,000 Hz). So, you can listen all planet sounds from space. Nearly all types of astronomical objects give off some radio radiation.The strongest sources of such emissions are the pulsars, certain nebula's, quasars, radio galaxies etc.. We can hear the sounds of space by using scientific instruments on spacecraft as our 'ears'.
