Plasma in our galaxy and within other galaxies, like plasmas in the dense plasma focus device, compress and twist themselves into filaments, with characteristic helix structures. One example is seen here, only 300 light years for the center of our Milky Way galaxy (which is 100,000 light-years across) this helical structure stretched 80 light years, but is identical in structure to the tiny filaments observed in the laboratory.

Another example is in the Cygnus Loop, a supernovae remnant 1,500 light years from Earth.
