* Nuclear Fusion: Stars are massive balls of mostly hydrogen and helium gas. Due to their immense gravity, the core of a star becomes incredibly hot and dense. Under these extreme conditions, hydrogen atoms fuse together to form helium, releasing a tremendous amount of energy in the process.
* Energy Release: This energy is primarily in the form of light and heat. This energy radiates outward from the core, traveling through the star and eventually reaching its surface, where it escapes into space.
* Visible Light: The energy released during fusion spans a wide range of electromagnetic radiation, including visible light. This is the light we see from stars.
In simpler terms: Think of a star as a giant furnace where hydrogen is constantly being burned to create helium, generating a massive amount of light and heat. This is what makes stars luminous.
