Funky Worlds Within Our Own system

     It is easy to imagine worlds within our solar system as having at least some similarities to Earth. All planets have a gravitational field and would have some breath-taking vistas. Then there are some differences that are small, every planet with an atmosphere is capable of carrying sound, though each has their own different range due to atmospheric density.
     Where the study of planetary sciences gets fun is where the big differences come out, especially on the Pandora's box of weirdness, Saturn. Our ringed planet has already been discovered to have some cool features including continuous auroras and crazy storms.

It is truly a beautiful planet.
     Now on to features that Saturn has that no other planet has. Due to its spin, Saturn has a hexagonal storm at its North Pole (the answer to why has been solved hopefully) which along with those auroras probably makes for one of the most stunning sights in the whole universe.
     Still the planet gets weirder. Recently it was discovered that Saturn has an electron beam link between it and the icy moon of Enceladus. While it is not unheard of for planets to have some link with their moons (in Jupiter it happens all the time), to my knowledge electron beams are pretty much a new thing in the realm of Saturn. So far how they think it happens is the result of ice geysers on the south pole of Enceladus (why these happen is a much deeper mystery in planetary heat flow). When they eject the ice particles into the thin atmosphere, they become electrically charged creating an ionosphere. With the motion on Enceladus plus this ionosphere through the magnetic field of Saturn comes an electromagnetic reaction, which in this case is an electron beam.
     Not only is the universe filled with mysteries and elegant solutions, our own Solar System can unveil these as well. I sincerely doubt that this will be the last we hear from the gem of the Solar System.

  1. That is very interesting. I wonder what actually causes the potential difference between the two bodies!
