    Implications of Polyextremophiles in Astrobiology Research
    (Springer, Cham, 2025) Gaurav Yadav, Sahaj Bharindwal, Anchal Mehrotra, Surati Kumari, Roohi, Renitta Jobby
    Astrobiology seeks to expand our knowledge of life by investigating how microorganisms survive and thrive in extreme environments, allowing us to better assess the potential habitability of distant worlds. Recent developments in the study of extremophiles, solar system planetary exploration, and exoplanet discovery and analysis are providing fresh insights into astrobiology and the possible distribution of life on other planets. Extraterrestrial environments frequently feature extreme conditions spanning multiple factors simultaneously. In order to survive in such complex and extreme conditions organisms need to develop adaptations that enable them to withstand a wide range of challenges. Therefore, a critical next step toward understanding the true limits of habitability is the study of polyextremophiles, or microorganisms that can survive under multiple extreme conditions simultaneously. This chapter outlines various extreme environments on Earth and the types of extremophiles found in these conditions. This chapter also explores the interesting world of polyextremophiles and the strategies they have evolved that enable them to thrive in these environments. Polyextremophiles can serve as invaluable model organisms in astrobiology, offering insights into the possibilities of life beyond Earth and to gain valuable knowledge for future space exploration missions.
