How are Plasma Jets made

[MGmirkin]

http://plasmascience.net/tpu/elec_currents.html Dr. Peratt implies Birkeland Currents are the power source. The energy at the poles of Earth seems inward. Are you certain about the poles of stars being outflows of energy. I have read Dr. peratts site many times, and it seems to be at odds with you folks. Is this a correct assessment? If so, why should i listen to you folks instead of the leading authority. No offense. Ít's possible the outflow model fits with Peratt and i just don't understand.

Well, for one, if we're referring to the Birkeland currents at the poles that power the auroras, then it's a 2-way flow. Closed "circuits" and all that.

http://en.wikipedia.org/wiki/Birkeland_current

Originally Birkeland currents referred to electric currents that contribute to the aurora, caused by the interaction of the plasma in the Solar Wind with the Earth's magnetosphere. The current flows earthwards down the morning side of the Earth's ionosphere, around the polar regions, and spacewards up the evening side of the ionosphere. These Birkeland currents are now sometimes called auroral electrojets. The currents were predicted in 1903 by Norwegian explorer and physicist Kristian Birkeland, who undertook expeditions into the Arctic Circle to study the aurora.

So they say...

I miss spoke. According to Peratt, Electrons go in one direction very quickly, while Protons move in the other direction, less quickly, i believe. But the power source to concentrate the Stars, and then power them is inward at the pole, i think. I assume the positive pole would be input, but now i'm guessing.
The Electrons streaming towards the Sun in a non polar manner opens a can of worms for me.
Some day in the distant future i hope to be comfortable with this.

My point is, the Plasma Jets are the Birkeland Currents entering Gas Giants, Stars, and Galaxies that are so active, our sensors can detect them. All of the Planets, Stars, or Galaxies have these Jets, but our instruments can't detect them in most cases.
Or not?

I wonder what our night sky might look like if we could see all the plasma currents that do not give off visible light due to their low density or energy levels. I did read very recently, but didn't bookmark, about an imaging development that would allow for a 'sweep' of a huge range of spectrum, converting the detected radiation to visible wavelenghts, in real time.

The little image at the top of this page http://public.lanl.gov/alp/plasma/elec_currents.html is what I think we might see, but maybe we would see a mind boggling collection of intertwined currents in a huge range of sizes, along with knots, pinches and who knows what else.

Here is a new press release on Black Holes and Plasma Jets.
http://news.bbc.co.uk/2/hi/science/nature/7364206.stm

I might as well also point out that the article doesn't apparently state what the mechanism they think they found is:

In a report in the journal Nature, US researchers say they have worked out how black holes emit jet streams of particles at close to light speed.

The University of Boston team say the streams originate in the magnetic field near the edge of the black hole.

They say it is within this region that the jets are accelerated and focused.

[...]

Professor Alan Marscher of the University of Boston and his colleagues claim they have delved deeper than ever into their heart.

Using almost every type of telescope known to humankind, Prof Marscher believes he has worked out where and how the jets - or blazars - are formed.

[...]

The astronomers had suspected that the supermassive black hole was spewing out plasma jets in a winding corkscrew, and they say that their observations have now confirmed just that.

[...]

"We think it is focused by a nozzle of sorts and it comes out at us," he was quoted by Reuters as saying.

They implicate "magnetic fields," but don't mention that such fields in plasma arise from electric currents.

They expected a corkscrew and they found a corkscrew. Not exactly "big news." Plasma filaments TEND to spiral! Especially when in the forum of electrically conducting filaments as in a plasma globe...

The closest I can see in that article to a mechanism is "nozzle of sorts." That really doesn't tell us much. Are they saying that something is pressurized and just kind of "squirts out?" Hopefully their paper is a bit more detailed / correct than this nonsense and/or that this article is just the far-too-stripped-down-layman's-version?

I have read a transcript of that interview with Marscher. It almost sounds as though he is attempting to describe gravity in electrical terms without ever using the word "electricity." The galling thing is that he speaks of black holes as though they are a scientific fact. Nothing he said in the transcript I read actually made any real sense, however.

Giday A, and welcome. Wouldn't happen to have a copy of that manuscript handy? If it's too much to post (with appropriate credits, of course) maybe you could email a copy to me. My address can be found at the bottom of any page at PlasmaResources.com.

Another article, popular summary, on the same subject:
http://www.space.com/scienceastronomy/0 ... lazar.html

Same stuff- corkscrews, twisting magnetic lines, black holes as fact
also:

"We got an unprecedented view of the inner portion of one of these jets and gained information that's very important to understanding how these tremendous particle accelerators work," said Boston University astronomer Alan Marscher, who led the research team. The results of the study are detailed in the April 24 issue of the journal Nature.

There is an interesting comment at the bottom, by "invisible_ghost." He/she sounds like somebody from this forum!

Keep in mind the "image" is an artist's impression. Anyway, they seem to implicate the "magnetic fields" in accelerating the particles. But where do the magnetic fields arise from? Electric currents, yes? According to Maxwell, anyway. They seem to have half the equation and be missing the other... No?
