How stars shine: the secret of fusion
Stars like our Sun generate incredible energy by fusing hydrogen into helium in their cores, a process that illuminates the universe and creates essential elements.
Stars, including our Sun, are cosmic powerhouses fueled by thermonuclear fusion. Deep within their cores, hydrogen atoms collide and merge under extreme heat and pressure, forming helium. This incredible process, occurring at temperatures of 15 million degrees Celsius in the Sun, converts a tiny fraction of hydrogen's mass into immense energy, following Einstein's E=mc².
