Describe about astronomers?</h3>
The two main categories of astronomers are observational and theoretical. Direct observations of celestial objects are made by observational astronomers, who then evaluate the results. Theoretical astronomers, on the other hand, develop and research models of phenomena that cannot be seen. Because a system of stars or a galaxy has a life cycle that lasts millions to billions of years, astronomers must take photographs of various systems at distinct stages in order to understand how they create, develop, and die. They build models or run simulations using these data to theorize about how various astronomical objects function.
