How does the Sun generate its enormous energy output?
Tap your pick
The Sun's energy comes from nuclear fusion, where hydrogen atoms combine to form helium in its core, releasing vast amounts of energy in the process. This is the same process that powers hydrogen bombs, but on a cosmic scale, providing the heat and light essential for life on Earth.
