Although space is a vacuum, that doesn't mean there is no sound in space. Sound exists as electromagnetic waves. All astronomical bodies emit radio waves and these are captured by specially designed instrument known as astronomical interferometer. These devices extract sound from the radio waves within the range of human hearing(20-20,000 Hz). read more
