NASA's Next Search for Life Is in Extraterrestrial Oceans

The video explores the potential for life in the solar system's ocean worlds, focusing on Europa. It discusses the discovery of hydrothermal vents on Earth, which changed our understanding of life's energy sources. The Europa Clipper mission aims to study Europa's habitability, with future missions planned to explore further. The video highlights the importance of these missions in understanding life's potential beyond Earth.
