Detailed explanation-1: -For the first time, America produced pure energy (carbon-free energy) like the Sun through nuclear fusion.

Detailed explanation-2: -United States has announced a nuclear fusion breakthrough, a historic step towards the promise of ‘near-limitless’ clean energy and may help the fight to curb climate change.

Detailed explanation-3: -But the shining of the Sun and the glittering of the stars were to remain an inexplicable wonder until the early years of the 20th century. In 1920, British astrophysicist Arthur Eddington (1882-1944) was the first to suggest that stars draw their apparent endless energy from the fusion of hydrogen into helium.

Detailed explanation-4: -Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.

Detailed explanation-5: -In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy.
