Astrophysical plasma is a state of matter found in space, consisting of charged particles such as electrons and ions. It is created under extreme conditions, like those in stars, including our Sun, where temperatures and pressures are high enough to strip electrons from atoms. This ionized gas plays a crucial role in various cosmic phenomena, including solar flares and the formation of galaxies.
In the universe, plasma makes up about 99% of all visible matter. It can be observed in regions like nebulae and quasars, where it emits light and interacts with magnetic fields. Understanding astrophysical plasma helps scientists learn more about the dynamics of the universe and the behavior of celestial bodies.
