Thanks to NASA scientists, everyone can now listen to the sound of a celestial body larger than Mercury.
NASA launched the Juno a spacecraft to study the largest planet in the Solar System, Jupiter. The 3,600kg structure arrived at its destination in 2016, and since its mission was completed in 2018, it has been conducting further measurements in the area.
The probe flew just 1038 km from the largest moon of Jupiter (and the Solar System) on June 7, Ganymedes and above the surface, the electrical and magnetic radio waves recorded during the encounter were aligned with the human ear by NASA scientists, so now we too can hear the “noises” of the celestial body.
The sound of a moon the size of three-quarters of Mars may surprise many, as the end result is most like the beeping of R2-D2, the rolling astrodroid of Star Wars. The real curiosity of the recording, however, is that you can see the moment when Juno crossed the Ganymedes. magnetosphere from one region to another.
“This soundtrack is wild enough to make us feel like we’re there when Juno sails past Ganymedes for the first time in more than two decades. If we look closely, we can hear a sudden shift to higher frequencies around the middle of the recording, which Indicates entry into another region of Ganymedes magnetosphere.
writes NASA. By the way, Ganymedes, with its diameter of 5,268 km, is 26% larger than Mercury, but its mass is only 45% that of the densest planet in the Solar System. The Hubble Space Telescope recently found water vapor in the atmosphere of the vast celestial body, and since 2015 it is assumedthat a salty ocean hiding more water than the earth is hiding beneath its surface.
