What is actually inside a star?In this episode of The Universe Explained, we travel from the centre of a star to its visible surface. We explore how gravity holds a star together, how nuclear fusion produces energy, and how that energy moves through the radiative and convection zones before escaping into space as light.Using the Sun as our main example, this video explains:• Hydrostatic equilibrium and stellar stability• Nuclear fusion inside the core• How hydrogen becomes helium• The radiative zone and the photon random walk• Convection currents inside a star• The photosphere and solar granulationA star is not simply a giant ball of fire. It is an enormous sphere of plasma governed by gravity, pressure, nuclear physics and magnetic fields.Subscribe to follow The Universe Explained and join the journey as my scientific knowledge, projects and research develop.Playlist:The Universe ExplainedNext episode:How Do We Know What Stars Are Made Of?Corrections and updates:Any corrections or important updates will be added to this description and documented through ProjectScientist.#Astrophysics #Astronomy #Stars
