Our Sun lies 93,000,000 miles away, surrounded by the vacuum of space.
Sound won't travel through space, of course. But with the right instrument, scientists can "hear" pulsations from the Sun.
astronomers at Stanford University can record acoustical pressure waves in the Sun by carefully tracking movements on the Sun's surface. To do this, they use an instrument called a Michelson Doppler Imager (MDI), mounted on the SOHO spacecraft, circling the Sun 1,000,000 miles from Earth.
