but these currents have nothing to do with the luminosity of the stars themselves, or so it is said.
http://plasmauniverse.info/CIVmonterey.htmlPeratt said that the filaments between the stars are not visible themselves but are observable with radio telescopes that can observe space at much longer wavelengths than are visible to the human eye. Prof. Per Carlqvist, a researcher at the Royal Institute of Technology in Stockholm, estimated that the interstellar filaments found by Verschuur conducted electricity with currents as high as ten-thousand billion amperes.
"The individual filaments in space are often called Z-pinches. These Z-pinches occur when current-carrying plasma 'pinches' itself into a filament by a magnetic field the current produces around the plasma. Z-pinches, such as those produced on the Sandia National Laboratories 'Z' machine, are among the most prolific producers of X-rays known," cited Peratt.
The United States Department of Energy funded Z-machine at Sandia has surprised the scientific community during the last few years by breaking all records in the production of high intensity X-rays from wire filaments converted into plasmas by million-volt pulses. Such filaments have already been discovered in our own solar system. For example, the aurora on Earth is known to be caused by million ampere currents flowing down the Earth's magnetic field lines at the northern and southern poles while similar were found by planetary explorer spacecraft to connect the planet Jupiter with its closest satellite Io.
That such currents existed on a much larger scale outside the solar system and beyond the reach of spacecraft has been a topic of conjecture among astronomers and space plasma scientists. According to Igor Alexeff, President of the Nuclear and Plasma Sciences Society hosting the conference, "It's not unusual that neutral hydrogen in space should show such well organized current structures; plasma also acts in a lifelike and intelligent way in laboratory experiments and in naturally occurring plasmas such as lightning."
