While there is a lot of negative press about NASA in alternative news arena, linking its foundation to a murky sub-story of Nazi infiltration, some of the scientists working there have their minds firmly focused on space, and discovering its mysteries through exploration and analysis. Jupiter is a potential future second sun in our near neighbourhood, and it has a moon, Ganymede, in its orbit that has some interesting features, such as polar zone auroras formed by plasma in Jupiter's magnetosphere. Nasa gathered this data from their space probe, Galileo back in 1996 but have revisited the same data for further analysis and brought forward new information.

"As it cruised around Jupiter, Galileo also happened to fly right through an explosive event caused by the tangling and snapping of magnetic field lines. This event, called magnetic reconnection, occurs in magnetospheres across our solar system. For the first time, Galileo observed strong flows of plasma pushed between Jupiter and Ganymede due to a magnetic reconnection event occurring between the two magnetospheres. It’s thought that this plasma pump is responsible for making Ganymede’s auroras unusually bright."


There's a great pdf graphic "Ganymedes_magnetosphere_infographic" at the link which is too large to upload here. It depicts Ganymede, the only moon of Jupiter to have its own magnetosphere, which is cocooned within Jupiter's own magnetosphere. This offers protection from interstellar radiation and any harmful incoming radiation from the Sun.

I'd not thought about the intense and complicated magnetic interchange between a large planet with so many moons. It blew my mind for a moment, but then I was able to reconnect :-D

The 'magnetic reconnection' seems right out of the theories of the Electric Universe.

Apparently, according to Ben Davidson at Suspicious Observers (sorry can't find the youtube video just now) in a similar way you describe, the Earth is protected by Sol's solar wind, particularly when we have lots of sunspots. But we are entering a solar minimum now. Less protection.
Plus, he argued that we get less protection around now for 2 other reasons
- we are entering a new area of space that has less 'space dust' to act as a shield. This is a very 'big picture' view.
- the magnetic poles are accelerating their shift from 'the former north (and south) poles', making Earth's own magnetosphere less stable.
He also made the point that we are seeing increased 'sensitivity' to even 'smallish' CMEs or other energetics coming our way. For this he points to the timing of several airport shutdowns, transformers that 'spontaneously' (i.e. we don't know why) set fire and increased geopathic stresses; earthquakes, volcanoes and such.

Sound scary?
This also sound like the setup for increased cosmic energies... hmm, that's beginning to sound a lot like an event we've all heard of;)

Also, I find it intriguing that the magnetic lines around the equatorial area get 'bent'. Wonder why?
Love the dates flashing by in the lower left corner too.

very interesting, so it makes to moons of jupiter quite special, the other one is Io as the most active volcanic system found in the solar system
