Why dosn't all rock (i.e comets) behave like the moon in the solar "wind" (electric current)?
Seems it happens on Enceladus as well!!
Again what causes the ionisation to happen? RC?
What about our Moon when it passes thru the Earths magnetotail?
Typically another misunderstanding by Sol88 (who is surprised?) And quote mining, leaving out the important part from the link:
Heated vents at the south pole of the moon release a plume of material, consisting mainly of icy grains and water vapour, into space.
This is neutral (not-ionized) icy and water, thank you very much.
Which interacts with the plasma in the Kronian magnetosphere
Measurements from the Cassini Plasma Spectrometer (CAPS) and the Magnetospheric IMaging Instrument (MIMI) show that both the moon and its plume are continuously soaking up the plasma, which rushes past at around 30 kilometers per second, leaving a cavity downstream. In addition, the most energetic particles which zoom up and down Saturn’s magnetic field lines are swept up, leaving a much larger void in the high energy plasma. Material from Enceladus, both dust and gas, is also being charged and forming new plasma.
The interaction of the magnetospheric plasma and the neutral plumes will ionize the particles in the plumes.
They do write that
“Enceladus is the source of most of the plasma in Saturn’s magnetosphere, with ionised water and oxygen originating from the vents forming a big torus of plasma that surrounds Saturn.
which is shorthand for what I wrote above.
Just another nail to Sol88's credability in reading even the most simple of news stories.
