- Astronomer — A scientist or highly qualified specialist in astronomy; a researcher who deals with the observation, measurement, cataloging, and physico-mathematical interpretation of the positions, movements, composition, and evolution of celestial bodies and matter in the universe. Their activity involves utilizing advanced optical instruments, radio telescopes, or satellite data to study cosmic phenomena, from nearby asteroid orbits to the structure of distant galaxies.
- Astronomer — A woman who works as an astronomer; a female specialist or researcher in astronomy who deals with the study of the structure, positions, and evolution of celestial bodies. She uses physico-mathematical models and high-power optical or electronic instruments to document phenomena in the universe, making an essential contribution to fields such as spectral analysis or exoplanet discovery.
- Astronomy — A fundamental and natural science that deals with the study, observation, measurement, and physico-mathematical interpretation of celestial bodies (stars, planets, satellites, comets, asteroids, galaxies), cosmic structures, and the universe as a whole. This discipline investigates the origin, evolution, chemical composition, and motion dynamics of matter and energy in extra-atmospheric space, being one of the oldest branches of human knowledge.
