Core - Hottest and most dense part of a star where nuclear fusion occurs, Radiation zone - Dense layer where heat radiates from the core to outer layers, Convection zone - Less dense fluid layer that transfers heat from the core to the star surface by convection currents, Photosphere - Visible surface of a star , Chromosphere - Thin layer of hot slowing gas only visible when a star is eclipsed, Corona - Outermost layer of gas surrounding a star , Magnetosphere - Magnetif field of a star produced from movement of charged particles inside the star, Sunspots - Small cooler areas on the visible surface of a star, Solar prominence - Arcs of charged gas particles that sometimes stick out of a stars surface, Solar flare - Violent eruptions of charged gas particles that get fired into space, Coronal mass ejection - Extremely large scale solar flares, Solar wind - Constant stream of charged particles and radiation that is pushed off the surface of a star in all directions all the time,
