The pictures of its ‘surface’ are unbelievable, but the real curiosity for space enthusiasts is the sound of Ganymede. NASA NASA’s Jet Propulsion Laboratory (JPL) has released a 50-second audio track on YouTube.
The sound was captured by Juno’s Waves instrument. There is a sudden increase in the pitch of the sound around 30 seconds in the video.
Researchers have explained that the sudden change in pitch is due to the movement of the spacecraft from one region of Ganymede’s magnetosphere to another.
William Kurth, an investigator at Juno, said the sudden change in the frequency of sound could be due to Ganymede’s move from night to day.
Like the Moon, the eyes of scientists are also on Mars. A large amount of water has also been found on Mars. According to a new study by the European Space Agency (ESA), water is hidden beneath the surface of the Valles Marineris Valley of Mars.
The European Space Agency (ESA) and the ExoMars Trace Gas Orbiter (TGO) have discovered large amounts of water in this valley. Now TGO’s FREND (Fine Resolution Epithermal Neutron Detector) is investigating these discoveries by monitoring the hydrogen concentration in the topsoil of Mars. Hydrogen is the main indicator of water concentration.
