If you were attending a concert of the sun, what would you hear? You probably would not need earplugs. NASA released a soundtrack this week that captures the sun's waves, loops and eruptions, and they sound like a deep, pulsating noise.
To generate the hot audio, the Stanford Experimental Physics Lab has sonicated data from the European Space Agency (NASA) and Solar Solar and Heliospheric Observatory (more on how this data was processed here). The vibrations allow scientists to study complex movements within the star, from solar storms to solar flares that shoot hot particles and plasma into space.
"We are finally beginning to understand the layers of the Sun and the complexity," said Alex Young, Deputy Director of Science in the Heliophysics Science Division at the NASA Goddard Space Flight Center, in a statement. "This simple sound gives us a probe within a star."
The sun sounds may not make you stand up and dance, but they offer a fascinating hearing of natural vibrations that can not be heard by turning one ear to the clouds.
"Waves travel and bounce in the sun, and if your eyes are sensitive enough they might actually see it," said Young.
NASA posted the audio to Soundcloud, where the audience had amusing comments. Wrote one: "What message do you get if you play this backwards?" Wrote another: "Amazing drums here."
This is an exciting summer for our next star. In addition to an LP recording, a close encounter with the NASA's Parker Solar Probe is planned, which
The aircraft is due to launch on July 31and show how much heat it can absorb shortly thereafter. It will be eight times closer to the sun than Mercury, a region that has never been explored.
Of course, if the moon is more your thing, Fridaythe longest of the century that will show a "blood moon".
And as we record this heavenly show, we're all looking forward to seeing Sun Sounds, The Remix.
