The solar wind is a stream of charged particles, primarily electrons and protons, that flow outward from the corona at incredible speeds. Roughly 74% of its mass is hydrogen, the same light gas that fuels stars across the cosmos.
The Sun: A Dynamic and Volatile Sphere
Deep within the core, where temperatures exceed 15 million degrees Celsius and pressure is immense, hydrogen nuclei collide with such force that they overcome their natural repulsion. The Sun in Cosmic Context.
The number of sunspots fluctuates on an roughly 11-year cycle, moving from a period of relative calm (solar minimum) to one of intense activity (solar maximum). These are regions of intense magnetic fields that inhibit convection, making them appear cooler and darker than their surroundings.
The Sun's Dynamic and Volatile Nature
Surface Activity and Solar Dynamics Sunspots and Solar Cycles The sun is not a calm, steady ball of light. Beyond that is the convective zone, where hot plasma rises, cools, and sinks in a pattern similar to boiling water.
