Exoplanet colonization refers to the process of establishing human settlements on planets outside our solar system, known as exoplanets. These planets are located in the habitable zone, where conditions may allow for liquid water and potentially support life. Scientists study various exoplanets to identify those that could be suitable for human habitation. To achieve colonization, advanced technology is required for space travel, life support, and sustainable living. Concepts like terraforming, which involves modifying a planet's environment to make it more Earth-like, are often discussed. Research in astrobiology helps us understand the potential for life and the challenges of living on these distant worlds.
