Starlight

Starlight is the light emitted by stars, particularly referring to the visible light that is detectable by the human eye. It is a result of nuclear fusion processes occurring within stars, where hydrogen atoms fuse to form helium, releasing energy in the form of light and other electromagnetic radiation. The term is often used poetically or romantically to describe the light from stars in the night sky, contributing to the beauty and wonder of celestial observation. In Hebrew, starlight is translated as אור הכוכבים (or ha-kokhavim). In Spanish, it is luz de las estrellas, in French, lumière des étoiles, and in German, Sternenlicht. Starlight plays a crucial role in astronomy, as the study of its spectra provides valuable information about the composition, temperature, and motion of stars. Additionally, the analysis of starlight has been instrumental in the development of our understanding of the universe, including the discovery of exoplanets and the expansion of the universe.
