Sounds from the Solar System’s largest satellite reach Earth

(ORDO NEWS) — The device of the mission “Juno”, orbiting Jupiter, transmitted data on its flyby of the largest satellite of the solar system – Ganymede. The data contains sounds emanating from the “lunar” surface. The 50-second soundtrack was generated from data collected during the mission’s close flyby of Jupiter’s moon.

The sound was shown at the fall meeting of the American Geophysical Union in New Orleans. The sounds were picked up by the Juno Waves instrument, which tunes in to electric and magnetic radio waves generated in Jupiter’s magnetosphere. Scientists have moved these frequencies into the audio range to create an audio track.

“If you listen carefully, you can hear a dramatic change to higher frequencies around the middle of the recording, which represents an entrance to another region of Ganymede’s magnetosphere,” said principal investigator Scott Bolton.

NASA reported that at the time of its closest encounter, the spacecraft was within 1,038 kilometers of the satellite’s surface and was moving at a relative speed of 67,000 kilometers per hour. Along with the sound, the Juno crew also released an image of Jupiter’s faint dust ring taken from inside the ring as seen by the spacecraft. The image also shows the arm of the constellation Perseus.

Data from the Juno spacecraft show that the planet has experienced changes in its magnetic field over the past five years and that the Great Blue Spot is drifting eastward at about two inches per second relative to the rest of Jupiter, traversing the entire planet in about 350 years.

Scientists said that cyclones at Jupiter’s poles are likely similar to ocean eddies and can provide insight into the physical processes at work on Earth.
