If you have been to attend a live performance by the sun, what would you hear? You in all probability would not want earplugs. NASA launched a soundtrack this week that captures the sun’s waves, loops and eruptions, and they sound like a low, pulsing hiss.

To produce the scorching audio, the Stanford Experimental Physics Lab sonified information from the European Space Agency and NASA’s Solar and Heliospheric Observatory (more on how that data was processed here). The vibrations let scientists research advanced motions inside the star, from photo voltaic storms to photo voltaic flares that shoot scorching particles and plasma into house. 

“We are finally starting to understand the layers of the sun and the complexity,” Alex Young, affiliate director for science in the Heliophysics Science Division at NASA’s Goddard Space Flight Center, said in a statement. “That simple sound is giving us a probe inside of a star.”

The photo voltaic sounds won’t get you up and dancing, however they do supply a captivating hearken to pure vibrations that may’t be heard simply by turning an ear towards the clouds. 

“Waves are traveling and bouncing around inside the sun, and if your eyes were sensitive enough they could actually see this,” Young mentioned.

NASA posted the audio to Soundcloud, the place listeners had some amusing feedback. Wrote one: “What message do you get when you play this backwards?” Wrote one other: “Amazing drums here.” 

This is an thrilling summer time for our closest star. In addition chopping an LP, it is set for an in depth encounter with NASA’s first-of-its-kind Parker Solar Probe spacecraft, which is getting ready to “touch the sun.”

The craft is about to launch as quickly as July 31 outfitted with a “cutting-edge heat shield” and can reveal how a lot warmth it might deal with shortly thereafter. It will come eight instances nearer to the sun than the orbit of Mercury, a area of house that is by no means been explored earlier than.   

Of course, if the moon is extra your factor, Friday brings a total lunar eclipse, the longest of the century, that can showcase a “blood moon.” 

And whereas we’re taking in that celestial present, we’ll all eagerly await Sun Sounds, The Remix.
