Nuclear fusion is a process in which two light atoms, such as hydrogen atoms, combine to form a heavier atom, releasing a large amount of energy in the process.
This phenomenon occurs in the interior of stars, where high temperatures and pressures allow nuclei to come close enough to fuse.
Nuclear fusion is a potential source of clean and abundant energy, as it uses readily available materials and produces minimal waste. However, we are still developing the technology necessary to efficiently control it here on Earth.
