The sun is not silent. in fact, it has a surprisingly soothing sound.
Have you ever listened to the sun? With data from the European Space Agency (ESA) and NASA's Solar and Heliospheric Observatory (SOHO), you can now do it. Using 20 years of data on the dynamic movement of the sun's atmosphere, researchers have allowed us to listen to the eruptions, curls, waves and other activities of the sun.
It turns out that the sun produces a pulsating and low "heartbeat". But these sounds are more than the hottest pieces of NASA scientists. Listening to the sun gives scientists a different way of observing and studying not only the sun of the Earth, but also of other stars in the universe, according to a statement.

"The waves travel and bounce inside the sun, and if your eyes were sensitive enough, they could actually see that," Alex Young, deputy director of science at the Heliophysical Sciences Division at NASA's Goddard Space Flight Center In a report, the use of a solar observatory to measure the sun's vibrations – which can be translated into sounds – reveals what's going on inside and can help scientists study everything from solar flares to coronal mass ejections to the sun. to the declaration.
"We do not have a direct way to look inside the sun, we do not have a microscope to zoom in to the sun's interior, so use a star or the vibrations of the sun allows us to see inward ".
The Stanford Experimental Physics Laboratory transformed SOHO data into a "song". They worked with the natural vibrations of the sun, which make up the buzz and the "heartbeat" that you can hear in the recording.
To create the above audio clip, researcher Alexander Kosovichev of Stanford University processed 40 days of data from Michelson Doppler Imager (MDI) of SOHO. By dealing with vibrations, it removes the effects of spacecraft motion, selects clear sound waves that would be clearer to hear and accelerates data by a factor of 42,000 to bring it to the audible range for humans.
With this strange, soothing and stellar audio, scientists "can see huge floods of solar matter circulating, we finally begin to understand the layers of the sun and the complexity, which gives us a probe to the Inside one I think that's a good thing, "said Young in the release.
