Observers play a crucial role in the field of Astronomy, as they are responsible for collecting data about celestial objects and phenomena. By using telescopes and other instruments, they can study stars, planets, and galaxies, contributing to our understanding of the universe. In addition to professional astronomers, amateur observers also contribute significantly to the field. They often participate in citizen science projects, helping to track asteroids, monitor variable stars, and contribute to the discovery of new celestial bodies, making astronomy a collaborative effort between professionals and enthusiasts alike.
