- Astrobiologist — A scientist or specialist who works in the field of astrobiology; a researcher focused on the interdisciplinary study of the origin, evolution, distribution, and future of life in the universe. They combine knowledge of biology, chemistry, geology, and astronomy to investigate potential biospheres on other celestial bodies, the survival limits of organisms in extreme environments, and cosmic biosignatures.
- Astrobiologist — A woman who works as an astrobiologist; a female specialist in the scientific investigation of the chemical and biological premises of life outside Earth. Her activity includes laboratory simulations of exoplanetary atmospheres, the study of extremophile organisms, and the interpretation of spectrographic data obtained from space telescopes to identify potential extraterrestrial habitats.
- Astrobiology — An interdisciplinary branch of science that studies the origin, evolution, distribution, and future of life in the universe, both on Earth and in outer space. It combines principles from astronomy, biology, chemistry, geology, and planetary physics to understand how habitable environments emerge, how life develops in extreme conditions, and how biosignatures can be detected on other planets or natural satellites.
