Astronomers are scientists who study the universe, its objects and how it works. They aim to push the boundaries of human knowledge about how the universe works by observation and theoretical modelling.

What do astronomers have to study?

Astronomers study the universe and the objects within it. For example, they may study planets, stars, galaxies, asteroids, black holes, and other celestial bodies. They use radio and optical telescopes on earth, as well as space-based telescopes and other tools to make observations and collect data.

What does a astronomer do at work?

In summary, astronomers are basically physicists that study how the universe works. Observational astronomers use telescopes to study the properties of things like the Big Bang and interpret those observations, using their knowledge of physics, to help us further understand the properties and evolution of the Big Bang.
