===== 1. Plasma is charged by definition. It is a state of matter in which electrons are stripped from nuclei, so free charges (ions and electrons) move independently. This means electric currents and magnetic fields are intrinsic to plasma. =====
# Stars and interstellar medium are plasma-rich. Stars are giant balls of plasma. Magnetic fields can cause localized or global charge separations, especially in solar flares, corona mass ejections, and other high-energy phenomena.
# Double layers and cell walls exist in space plasma. As Alfvén described, space can be divided into regions by current sheets, with differing magnetic and electric potential. These can span entire stars, stellar systems, or galactic structures.
# Electric fields can be shielded by Debye lengths, but: - In space, where densities are low and temperatures are high, Debye lengths can be enormous, allowing for vast-scale electromagnetic structures. - Interstellar filaments, jets from quasars, and cosmic web filaments may be examples of this.
# Modern Plasma Cosmology and Electric Universe theories explore this, but are controversial in mainstream physics. Still, many space plasma phenomena support large-scale electromagnetic structuring of the cosmos.
