First Detection of Life

The video discusses the Galileo spacecraft's mission to detect life on Earth by analyzing atmospheric data. It highlights the importance of chemical imbalances, such as methane and oxygen, as indicators of life. The role of liquid water in supporting life is emphasized. Galileo's observations provide a framework for future missions to detect life on exoplanets. The video also covers current and future technologies, like the James Webb Space Telescope, that will enhance our ability to study exoplanetary atmospheres and potentially discover alien life.
