Plasma physics is the study of plasma, which is one of the four fundamental states of matter, alongside solids, liquids, and gases. Plasma consists of charged particles, including ions and electrons, and is found in stars, including our Sun, as well as in fluorescent lights and plasma TVs. Understanding plasma helps scientists explore various phenomena in astrophysics, fusion energy, and space weather.
Researchers in plasma physics investigate how these charged particles interact with electric and magnetic fields. This knowledge is crucial for developing technologies like nuclear fusion, which aims to replicate the energy production of stars, and for improving spacecraft propulsion systems.
