An "estrella" is the Spanish word for "star," referring to a luminous celestial body visible in the night sky. Stars are massive spheres of plasma, primarily composed of hydrogen and helium, that generate light and heat through nuclear fusion. They are essential components of galaxies, including our own Vía Láctea. In addition to their astronomical significance, "estrella" can also refer to a person who is famous or highly regarded in a particular field, such as entertainment or sports. For example, a movie star or a sports star is often called an "estrella" in Spanish-speaking cultures, highlighting their prominence and influence.
