Solar flare

Do you know how the sun sounds like? Well, the NASA scientists actually can. They do listen to sun's low-frequency pulsing hum and what does it tell them? The scientists hear it in order to comprehend and learn about our host star's atmosphere.

ESA (European Space Agency) and the Solar and Heliospheric Observatory (SOHO) of NASA, which the American space agency had launched way back in 1995, acquires the raw information and then the Stanford Experimental Physics Lab researchers process and filter it and then increases its speed to make it audible to the human ear.

"Waves are traveling and bouncing around inside the Sun, and if your eyes were sensitive enough they could actually see this," said Alex Young, the associate director for science in the Heliophysics Science Division at the Goddard Space Flight Center of NASA.

This sound, captured by ESA and SOHO and modified by the Stanford Experimental Physics Lab, brings the natural vibration of the sun. It also gives the scientists a solid representation of the star's dynamic movements.

"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 of it," added Young.

Young also said,"We can see huge rivers of solar material flowing around. We are finally starting to understand the layers of the  and the complexity. That simple sound is giving us a probe inside of a star. I think that's a pretty cool thing."

Now, you can hear the sound of the sun too. Here it is:
