科学家捕捉到来自太阳发出的“心跳”声
科学家捕捉到来自太阳发出的“心跳”声

What does the Sun sound like? Perhaps you have never thought about what kinds of sounds the Sun makes, but scientists have found out. Researchers studied 20 years of data to listen to the Sun. They say the Sun produces a low, deep "heartbeat" sound. The scientists measured vibrations from the Sun. They translated these vibrations into different sounds. These can tell the scientists what is happening inside the Sun. 
The scientists explained how they created the Sun's sound. Researchers from the Stanford Experimental Physics Lab turned data from the space agencies into 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." Dr Young continued, "Waves are travelling and bouncing around 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 of the Sun and the complexity. That simple sound is giving us a probe inside a star. I think that's a pretty cool thing."
