Alien Worlds (GAYA 21B) - A Space Travel Documentary in Search of a New Earth. With modern technology, better telescopes, and the help of AI, we are discovering more and more potentially habitable planets in our Milky Way. What are conditions like there? Is there life, and if so, how did it evolve? To answer these questions, we would have to set out ourselves in a spaceship and travel many light-years through space in search of new life and distant worlds.
