Starlight

Starlight is the light emitted by stars as a result of nuclear fusion, where hydrogen atoms combine to form helium, releasing energy. This energy travels through space as electromagnetic radiation, which we perceive as the star's brightness and color. Despite traveling vast distances, some of this light reaches Earth, allowing us to observe stars even millions of light-years away. In essence, starlight is the cosmic glow of stars’ nuclear processes, providing insights into their properties and the universe's history.
