The video discusses the Kepler mission's goal of finding Earth-like planets by observing the dimming of stars as planets pass in front of them. Kepler's data has revealed that our galaxy contains billions of such planets. The video explains the methods used to detect these planets and how scientists extrapolate data to estimate the number of Earth-like planets. It also highlights the future of exoplanet research, including the potential for detecting life by analyzing atmospheric compositions.
