TED-ED: Why extremophiles bode well for life beyond Earth - Louisa Preston

Astrobiology is a scientific field that explores the possibility of life beyond Earth. It draws from various disciplines to understand how life forms and how it might exist elsewhere. While ancient beliefs imagined other worlds, modern science has only recently begun searching for extraterrestrial life. Life on Earth requires water, energy, and carbon, and can thrive in extreme environments. Mars and certain moons of Jupiter and Saturn are key targets for exploration due to their potential to support life. Astrobiologists continue to study Earth's extremophiles to better understand life's possibilities in the universe.

What are some of the moons of Jupiter and Saturn that astrobiologists are interested in?
