What does the Sun sound like? Perhaps you have thought about what kinds of sounds the Sun makes, but scientists have found out. Researchers from the European Space , NASA and the Solar and Heliospheric Agency studied 20 years of to listen to the Sun. They say the Sun produces a , deep "heartbeat" sound. The scientists used a observatory to measure from the Sun. They translated these vibrations into different . These can tell the what is happening the Sun. They can now understand more about solar flares, chemical reactions and other that happen inside the Sun and on its surface.
The scientists explained how they created the Sun's . Researchers from the Stanford Experimental Physics Lab turned data from the space into a "". Dr Alex Young said: "We don't have ways to look inside the Sun. We don't have a to zoom inside the Sun, so using a star or the Sun's vibrations allows us to see inside of it." Dr Young continued: "Waves are travelling and bouncing around inside the Sun, and if your were sensitive enough, they could see this." He added: "We are starting to understand the layers of the Sun and the complexity. That simple sound is giving us a inside a star. I think that's a pretty thing."
