Above this lies the chromosphere and the outermost layer, the corona, a region of superheated plasma that extends millions of kilometers into space and is visible only during a total solar eclipse. This outflow creates a vast bubble around our solar system known as the heliosphere, which acts as a protective shield against a significant portion of the high-energy cosmic rays coming from other parts of the galaxy.
Solar Layers: Core to Corona Structure and Dynamics
During peak activity, the sun can unleash powerful solar flares and coronal mass ejections, events that can disrupt satellites and power grids on Earth. Its surface is a landscape of magnetic activity, manifesting in dark spots known as sunspots.
This celestial body is not a solid surface but a churning mass held together by its own gravity and powered by nuclear fusion at its core. The solar wind is a stream of charged particles, primarily electrons and protons, that flow outward from the corona at incredible speeds.
