Astronomical features refer to the various natural phenomena and structures found in space. These include celestial bodies like stars, planets, moons, and asteroids, as well as larger formations such as galaxies and nebulae. Each of these features has unique characteristics, such as size, composition, and behavior, contributing to the vastness of the universe. Additionally, astronomical features can also encompass events like supernovae, which are explosive deaths of stars, and eclipses, where one celestial body moves into the shadow of another. Understanding these features helps scientists learn more about the origins and evolution of the universe.
