Astronomers are scientists who study the universe and its contents. They use a variety of tools, including telescopes, satellites, spacecrafts and computers to observe and analyze the stars, planets and galaxies in our universe. Astronomers also study the formation of stars and galaxies as well as their evolution over time. They search for new objects such as asteroids or comets that may pose a threat to Earth. Astronomers also research topics related to cosmology like dark matter or dark energy. In addition to observational astronomy, astronomers also use theoretical models to explain how the universe works on a fundamental level. Through their work, astronomers have helped us gain valuable insights into our place in the cosmos.
