Given sufficient temperature and pressure, 4 hydrogen nuclei fuse to produce helium, at the same time giving off energy in the form of heat and light and other forms of radiation. This means that stars, with a few exceptions such as super-massive stars, last for many billions of years.
The sun survives by burning hydrogen atoms into helium atoms in its core. In fact, it burns through 600 million tons of hydrogen every second. via GIPHY. And as the sun's core becomes saturated with this helium, it shrinks, causing nuclear fusion reactions to speed up â which means that the sun spits out more energy.
