. The moons of Jupiter Io and Ganymede leave a visible imprint in the brilliant aurora borealis of the planet
While the Earth has its own dawn, the aurora of Jupiter is remarkably different when it comes to the way it is created. Due to the planet's high plasma magnetosphere, charged particles will often reach Jupiter's atmosphere, causing a beautiful display of light that, in many ways, looks a lot like ours. Yet, as reported Phys.org there is no trace of footprints left in the auroras of the Earth caused by the moon.
Scientists discovered these fingerprints after badyzing data from NASA's Juno spacecraft. when Io was extremely close to Jupiter, the dawn of the planet had remained with weird squiggles. Research has shown that it looks a lot like a Von Kármán vortex, and scientists have noted that Io derives from Jupiter, as well as his odd imprint.
Just like the discovery fingerprint with Io, scientists have noticed that Ganymede also created the same type of imprint in Jupiter's aurorae when he was near. However, in the case of this moon, the imprint was discovered to have created two spots, almost as if it had been cut in half.

While scientists could not figure Why did Ganymede's footprints have to be divided in two, they observed that this moon is the only one in orbit around Jupiter endowed with a magnetic field of its own. For this reason, scientists believe that it is very likely that the doubling of footprints could be created because of the interaction between the distinct magnetospheres of these two celestial bodies.
Scientists are very interested in learning more about the footprints of Jupiter's moons. create in its dawn, because they believe it will help them better understand how powerful magnetic forces behave in situations like these. Because models have not yet been designed to predict this kind of bizarre behavior, scientists note that new models will have to be created.
The new study of how the moons of Jupiter cause auroras was published in . Science .
