The video explores the Milky Way galaxy, its formation, and life stages, comparing them to human life. It discusses how galaxy colors indicate age and star formation, with blue galaxies being younger and red ones older. Despite having star-forming gas, the Milky Way's star production is declining, suggesting it is entering a phase of death. Scientists use infrared observations to study the galaxy and investigate potential causes for its decline, including the role of supermassive black holes.
