What does the Sun sound ? Perhaps you have never thought what kinds sounds the Sun makes, but scientists have found . Researchers the European Space Agency, NASA and the Solar and Heliospheric Agency studied 20 years of data to listen to the Sun. They say the Sun produces a low, deep "heartbeat" sound. The scientists used a solar observatory to measure vibrations the Sun. They translated these vibrations different sounds. These can tell the scientists what is happening inside the Sun. They can now understand more solar flares, chemical reactions and other phenomena that happen inside the Sun and its surface.
The scientists explained how they created the Sun's sound. Researchers the Stanford Experimental Physics Lab turned data the space agencies a "song". Dr Alex Young said: "We don't have straightforward ways to look inside the Sun. We don't have a microscope to zoom inside the Sun, so using a star or the Sun's vibrations allows us to see inside it." Dr Young continued: "Waves are travelling and bouncing inside the Sun, and if your eyes were sensitive enough, they could actually see this." He added: "We are finally starting to understand the layers the Sun and the complexity. That simple sound is giving us a probe inside a star. I think that's a pretty cool thing."
