Scientists led by Dr. Alessandro Moore of the Institute of Space Astrophysics and Planetology of the National Institute of Astrophysics in Italy analyzed images of Jupiter received by the satellite Junona and noticed that the satellites Io and Ganymede "As the Earth, Jupiter has a glow, these permanent electromagnetic radiation are associated with the precipitation of a magnetospheric plasma in the ionosphere of the planet." In the light of Jupiter there are radiation characteristics. van, absent on Earth, associated with its moon: in the ionosphere, at the base of the magnetic field lines passing through the Galilean moons – Io, Europe and Ganymede – there are bright spots ", – said the scientist.
that while analyzing the images of "Juno", scientists have not noticed a single trace of Io, but a whole chain of light points, whose size can be adapted to the size of the satellite, at the same distance. The created pattern is similar to a trail of swirling swirls in both hemispheres, which are sometimes divided into wing arches
Thus, scientists have discovered that Ganymede leaves a double trace in the glow. These features suggest that the magnetohydrodynamic interaction between Jupiter and its moon may be more complicated than previously thought.
"These unusual patterns may be the result of magnetic interactions, close to the months, or interference between giant waves of electrical particles" authors of the study.
Junona was launched on August 5, 2011 from Cape Canaveral, Florida (USA), as part of the New Frontiers program. The Juno, in the orbit of Jupiter, worked on the Galileo probe, but Junona, the first in history, will fly the planet through its poles.
The device arrived at Jupiter on July 4, 2016. It will remain in the orbit of the planet for several years and will transfer new images to the ground. Once the work is finished, the probe will be destroyed
