Astronomers or astrophysicists study what goes on outside the Earth’s atmosphere. Their research focuses on the origin, structure, movements and evolution of solar systems, planets, galaxies, stars and other celestial objects.
Astronomy is based on physics and mathematics, where high-tech tools are used to gather huge amounts of information and analyze them with the help of computer programs that simulate movements and developments in the vast universe.
Most astronomers work at universities or related research institutions, such as in meteorology. Astronomers can also, for example, teach science subjects at secondary school level.
