- Stars give off light through a process called nuclear fusion, which happens when lighter elements are forced to become heavier elements1. Stars spend most of their lives repetitively compressing two hydrogen atoms into a single helium atom, releasing a lot of energy in the form of light and heat2. A star is a huge sphere of very hot, glowing gas that produces its own light and energy1. Anything that is hot will glow, and stars glow in different colors depending on their temperature34.Learn more:✕This summary was generated using AI based on multiple online sources.

Fusion happens when lighter elements are forced to become heavier elements. When this happens, a tremendous amount of energy is created causing the star to heat up and shine.coolcosmos.ipac.caltech.edu/ask/204-What-is-a-star-Stars spend most of their lives repetitively compressing two hydrogen atoms into a single helium atom – plus a lot of energy, which is released as light and heat.www.astronomy.com/science/how-do-stars-create-…Stars give off light the same way the filament in a light bulb does.
