When these nuclei fuse, they form helium, and in doing so, they release a tremendous amount of energy in the form of light and heat. 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).
How Nuclear Fusion Powers This Ball of Gas
How Nuclear Fusion Powers the Star At the heart of this gaseous sphere lies the engine of its existence: nuclear fusion. It is this continuous conversion of hydrogen to helium that provides the sun’s unwavering luminosity, the very energy that sustains life on Earth.
The Sun in Cosmic Context. Its surface is a landscape of magnetic activity, manifesting in dark spots known as sunspots.
How Nuclear Fusion Powers the Sun, a Ball of Gas
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. 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.
