An astronomer is a person who explores the mysteries of the Universe by observing stars, planets and galaxies. For him, the night sky is not just a beautiful view, but a source of information about the origin and evolution of the cosmos. Using telescopes and modern technology, he studies distant worlds, black holes and star clusters. Astronomers are unlocking the mysteries of the universe by analyzing light from celestial bodies and trying to understand processes beyond our planet, expanding the boundaries of our understanding of the cosmos.
