The next most abundant component is helium, making up about 24% of its mass, a byproduct of the very reactions that power the star. The Sun in Cosmic Context.
The Sun: Our Nearest Plasma Ball in Cosmic Context
Its surface is a landscape of magnetic activity, manifesting in dark spots known as sunspots. Solar Wind and the Heliosphere Even without a flare, the sun is constantly shedding material.
During peak activity, the sun can unleash powerful solar flares and coronal mass ejections, events that can disrupt satellites and power grids on Earth. The Layers: From Core to Corona The sun is not a uniform blob of gas; it is structured in distinct layers, each with unique properties and functions.
The Sun: A Dynamic Plasma Ball Beyond Gas
Roughly 74% of its mass is hydrogen, the same light gas that fuels stars across the cosmos. 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.
