An astronomer is a scientist who studies celestial objects, such as stars, planets, moons, galaxies, and the universe as a whole. They seek to understand phenomena that occur beyond Earth's atmosphere, including the origins, evolution, and eventual fate of these celestial bodies and the universe itself. Astronomers use various methods and tools, including telescopes, satellites, and computer models, to collect data and analyze the properties and behaviors of astronomical objects.
