In Episode 18 of Amazing Universe, we explore astrobiology — the scientific quest to discover life beyond Earth. The episode examines how scientists use the study of extremophiles on Earth to understand where life might exist elsewhere in the cosmos, such as on icy moons or distant exoplanets. We delve into the search for biosignatures, like oxygen and methane in planetary atmospheres, and the significance of the habitable zone, where conditions might allow liquid water to exist. From Mars rovers to space telescopes and upcoming missions to Europa and Titan, astrobiology is unlocking clues in the cosmic search for life.
