A group of researchers has just made the amazing discovery that Saturn has auroras that can be seen during the day, with some even appearing at noon, and all this is possible thanks to the super-fast rotation of this planet.
For their new study, the scientists badyzed the large amount of data that was recorded on the Cbadini spacecraft after it had completed its mission and collected as much information as possible during the 13 years it spent in orbit around Saturn, such as Phys.org Report .
Although generally we can only see auroras here on earth when there is total darkness, this is not the case for Saturn, a planet where one day is only 10 hours, even though it is 760 times more mbadive than Earth.
The new study has shown that when Saturn produces magnetic bursts that occur around midday, they help sound about magical auroras at noon on the planet, according to Popular Science .
Because of these diurnal auroras, researchers may be a little closer to understanding the strange X-rays they had previously detected on Jupiter, where odd pulses were also found at this time.
Zhonghua Yao, co-author of the new study, explained that the same process that is happening on Saturn may also be happening on Jupiter.
"We hope this process will also take place in Jupiter's magneto disk, which could be confirmed by NASA's Juno mission that is exploring the Jovian magnetosphere."

With the collision of magnetic fields, it is often they produce enormously powerful explosions. This can be seen in plasmas, which also have magnetic fields in them. As such, when the sun's plasmas suddenly come out and reach the Earth's magnetosphere, the magnetic reconnection of the magnetic field lines will occur when these lines break first and then begin to reconnect.
Past research on Saturn's auroras has made scientists aware of reconnection events throughout the magnetopause during the day, and also on the magneto disk on the side of the planet that is experiencing the night, with the planetary scientist of the European Space Agency Nicolas Altobelli noting that "during a reconnection event, this plasma is released and accelerates."
It is suggested that it depends on the speed of rotation of Saturn that makes this important reconnection possible, according to Zhonghua Yao.
"This means that planetary rotation plays a much more important role in driving the magnetic reconnection that we once considered."
