In a star like the Sun, four atoms of hydrogen eventually combine via fusion to make a heavier nucleus of helium. What makes fusion inside a star so useful is that the transformation of a light ...

Gov. Glenn Youngkin announced that the world's first nuclear fusion energy plant is expected to come to Chesterfield County. The science behind it is still being studied.

Eventually, all of the helium that was fused from the sun's original hydrogen supply will also be exhausted, and all fusion will cease. The star will eject its outer layers, creating a glowing ...

Stars are born, live and die in spectacular ways, with their deaths marked by one of the biggest known explosions in the ...

Every star we see in the night sky is like our sun. Sure, some are larger or smaller, and some are hotter or cooler, but all work the same way. Each is a thermonuclear fusion reactor that converts ...

When they reach the end of their long evolutions, smaller stars—those up to eight times as massive as our own sun—typically become white dwarfs. These ancient stars are incredibly dense.

That, paired with the fact that the fuel that goes into nuclear fusion — hydrogen or helium atoms — are very safe sources shows nuclear fusion has an inherent level of safety that few energy sources ...

hydrogen nuclei fuse together to form helium nuclei. As the star runs out of hydrogen, other fusion reactions take place forming the nuclei of other elements. The Big Bang produced hydrogen and ...

There are no CO 2 or other harmful atmospheric emissions from the fusion process, which means that fusion does not contribute to greenhouse gas emissions or global warming. Its two sources of fuel, ...

leading to a state of equilibrium between gravitational collapse and the energy released during fusion Key fact In a main sequence star, hydrogen nuclei fuse together to form helium nuclei.
