Life on Europa? What Conditions Make Europa Habitable? - Astrobiology | GEO GIRL
Is There Life on Europa? First, we need to ask the questions: Is there water on Europa? Are bioessential elements (C, H, N, O, P, S) present on Europa? Does Europa have enough energy for life? We go over each of these questions in this lecture and come to a definitive answer regarding Europa's habitability. But just because Europa might be habitable, does that mean Europa is inhabited? Not necessarily. But in either case, we explore the types of life that could live on Europa based on the compounds we know are present in Europa's ocean. Through this lecture, we learn that geological activity is of utmost importance when it comes to the possibility of life on Europa. Therefore, in the upcoming videos, we will cover the geological activity of Europa as well as the geologic history of Europa. Hope to see you there! ;D
