Nuclear fusion, the process that powers our sun, happens when nuclear reactions between light elements produce heavier ones. It's also happening -- at a smaller scale -- in a lab. Using a compact but ...

Construction continues in 2025 on the ITER fusion device, which is designed to prove that fusion can be a large-scale, carbon-free source of energy. (Photo: ITER) Fusion offers a promising clean ...

Nuclear fusion is the process that powers the sun and other stars through the combination of two hydrogen atoms into one helium atom. In that process, part of the mass of the hydrogen is converted to ...

It’s rarely appreciated just how much more complicated nuclear fusion is than nuclear fission. Whereas the latter involves a process that happens all around us without any human involvement, and where ...

Nuclear fusion has long been heralded as the future of energy. Replicating the process that powers the sun on Earth promises an endless supply of renewable energy without greenhouse gases. The concept ...

Fusion is the process of building up simple atoms into larger more complex ones. It releases a lot of energy, and occurs every day in the sun as well as every other star in the Universe. The trick for ...

The U.S. Department of Energy (DOE) announced on Dec. 13 “the achievement of fusion ignition.” The milestone is a major scientific breakthrough, decades in the making. Fusion, of course, is the ...

Fusion is a natural phenomenon that provides our planet with much of its energy—generated millions of miles away in the center of our sun. Here on Earth, scientists are trying to replicate the hot and ...
