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.
Letâs take a look at the conditions necessary to create nuclear fusion in stars and some of the different kids of fusion that can go on.

The core of a star is an intense environment.The pressures are enormous, and the temperatures can be greater than 15 million Kelvin.
