Astronomers study the universe and its contents, including stars, galaxies, planets, asteroids, comets, and more. They use telescopes to observe these objects, measure their distances and motions, and try to understand how they work. Astronomers also use computers to analyze data and create models of the universe. Additionally, astronomers must be familiar with a variety of scientific fields such as physics, chemistry, mathematics, and geology.
