We examine the pivotal role of Artificial Intelligence (AI) in both exoplanet discovery and futuristic space technologies. We explains how AI, particularly machine learning algorithms like neural networks, significantly enhances the detection and analysis of exoplanets by sifting through vast datasets from missions like Kepler and TESS, outperforming traditional human methods. Beyond detection, we discusses AI's increasing integration into space mission operations, including autonomous telescope scheduling, satellite management, and spacecraft navigation. Furthermore, we explores the philosophical implications of AI in the search for extraterrestrial life, highlighting both scientific benefits and challenges related to bias, while also forecasting AI's essential role in future space colonization, robotic exploration, and autonomous planetary mapping, enabling humanity's expansion beyond Earth.
