NASAs Galileo spacecraft surprised scientists when it revealed that Jupiters moon Ganymede generated its own magnetic field. But new research shows Ganymede also creates incredibly powerful waves that rocket particles to enormous energies.
Scientists revealed these huge electromagnetic waves while studying old data from Galileo, which orbited Jupiter from 1995 to 2003. The observations show another wild way that a moon can interact with the magnetic field of its planet.
Jupiters radius is around 11 times that of Earth, but it is perhaps 20,000 times more magnetic. This generates an intense radiation environment around the planet.
Typically, these waves around Jupiter have an amplitude a little higher than that of the magnetic field produced by the human brain. But when Galileo passed by the 3,274-mile-wide moon Ganymede, the wave height spiked a million times, to perhaps the strength of a magnetic field produce by a kitchen microwave.
As to where the waves come from, the interaction between Ganymede and Jupiter could cause an uneven distribution in electrons surrounding the moon. This could supply the necessary energy to generate the large waves in the magnetic field. But its more complex than that, according to the paper published in Nature Communications.
Moons without magnetic fields might make these kinds of waves also, though Jupiters moons Io and Callisto dont. There are a host of different variables that could determine whether the waves exist and how big theyll be, but determining all that will be up to future study.
U.S. and Europe both have plans to continue sending probes to the planet, and the accelerated particles could wreck manmade technology.
These results could also help scientists better understand the behavior of powerful magnetic fields and plasmas in general. Perhaps studying the radiation around Jupiter could help scientists find Jupiter-like exoplanets.

Didn’t I read once that Jupiter is a small star that never erupted into flame?
So this is a class 9 force screen? Zargon manufacture?
My back of the envelop calculations confirm that.
“Didnt I read once that Jupiter is a small star that never erupted into flame?”
Hey, this isn’t the Kimchi thread!
If you want on or off the Electric Universe Ping List, Freepmail me.
Yes, that is a theory. But in order to have been a star Jupiter’s mass would have had to be much more massive then it currently is. At least a hundred thousand times more massive.
What about Europa? They left out Europa, the one moon of Jupiter we can’t go to.
Is there life there? Movie fans want to know more about it.
“ALL THESE WORLDS ARE YOURS, EXCEPT EUROPA. ATTEMPT NO LANDING THERE.”
I dunno, I don’t think the great space coffee table is serious.
I’ma chance it.
Thanks BenLurkin .

Mass of the Planets and the Sun
http://www.smartconversion.com/otherInfo/Mass_of_planets_and_the_Sun.aspx
1.8986/.0059736=317.83179322 (Earths to make one Jupiter)
1.9891/.0018986 1047.6667018 (Jupiters to make one Sun)
If there is it’s got to be way down below the surface and living in very, very cold water. Europa’s an ice ball.
How do we know that they’re not credible magnetic waves? Surely, they’re not liars.
Jupiter’s mass is 1/1047 that of the sun. If it were 100,000 times more massive it would be 100 times more massive than the sun, and would be a super giant star.
In order to be a star, to fuse hydrogen into helium, requires enormous pressure and heat. Fusion only occurs at the very center of the sun, heat is transferred by convection to the surface and radiated away. The specific power generation of the sun is about the same as a bale of rotting hay, about one half watt per cubic meter. The sun just does it longer - for billions of years - and with a lot more cubic meters.
Off by a few orders of magnitude. The minimum mass for a red dwarf is around 80 Jovian masses. That is the minimum to start the p-p fusion chain. For brown dwarves of 13 to 80 Jovian masses, one might find deuterium burning or lithium burning, but that does not last long. The energy currently given off by Jupiter is largely due to gravitational contraction and isotope decay.
Sounds familiar...
Maybe they are positive waves?
