Makes sense that the Russians would actually attempt plasma experiments in zero G!

These are the usual self-sorting features of cosmic dusty plasma. The dust particles flow in the plasma according to their charge or possibly dipole moment orientation.

I would be interested in zero-G experiments of La Point's magnetic bowls (Primer Fields) and the geometric patterns their induced magnetism form on non-magnetic iron spheres exposed to the fields.

I don't know enough of the MHD physics to explain the void formation. Maybe Eugene might chip in on that one. The helices were dusty cosmic Birkeland currents.

Holy Cow! It's all right there. Galaxies, DNA(Birklend), even.. 'black holes'
Plasma, is the First State of Matter

Most of the results make sense to me, but I"m still scratching my head as to how the plasma ends up flowing around empty regions of the vacuum. I don't fully understand that behavior.

[...] empty regions of the vacuum.

I have a very hard time to put my head around this, but a thought came up: Is it empty? Aren't there photons there?

I meant that there are areas that don't seem to contain plasma or other forms of actual matter, yet the plasma in the chamber looks to be flowing around it, as though a double layer has formed between the plasma and he center of the empty(ier) region. That surprised me.

I think that the pressure is so low, that you can see the
influence of the electron-shells of the ions.

The electron-shells have certain resonating frequencies.
This means that they connect better at certain angles (Nx90 degrees/ Nx60 degrees).
This gives the plasma the tendency to form chains or leaf-structures.

This would mean that the structures would very much depend on
the type of ions. And should be testable.

Yeah, agree - but I was thinking more in lines of maybe the field gives the photons some resonnant properties. And like the detection screen in the double slit experiment; empty areas there too... . But I could be way off in the strawberry field looking for blueberries here. (I'll close my own screen now... )
