An international group of scientists from Belgium, the US and Italy has published a new study. Jupiter's Io and Ganymede moons leave a noticeable amount of footprints in the planet's bright polar lights.
While Earth has its own aurora, the aurora of Jupiter is remarkably different in how it is created. Because of the planet's strong plasma-driven magnetosphere, charged particles often hit the atmosphere of Jupiter, resulting in a great display of light that resembles ours in many ways. However, as reported by Phys.org there are no traces of footprints in the aurora of the Earth caused by the moon.
Scientists discovered these footprints after analyzing data from NASA's Juno spacecraft When Io Jupiter was very close, the planet's auroras had strange rings. Research showed that it was very similar to Von Kármán's vortex, and scientists found that when Io drifted away from Jupiter, his strange footprint.
Just like the footprint discovered with Io, scientists noticed that Ganymede was also creating the same kind of footprint in the polar lights of Jupiter when it was near. In the case of this moon, however, it was discovered that the footprint produced two points, almost as if it had been split in half.

While scientists were unimaginable Why should the footprints created by Ganymed be split into two? They observed that this moon is the only one orbiting Jupiter, which has its own magnetic field. For this reason, scientists believe that it is very likely that the duplication of footprints will be generated due to the interaction between the different magnetospheres of these two celestial bodies.
Scientists are keen to learn more about the footprints of these Jupiter moons created in their polar lights, which they believe will help them better understand how strong magnetic forces behave in such situations. Since no models have been built that have predicted this strange behavior, scientists are finding that new models need to be created.
