The discovery of new planets in nearby galaxies always attracts the attention of astronomers. One of the closest galaxies that is the focus of research is the Andromeda Galaxy, which is approximately 2.537 million light years from Earth. As telescope technology advances, such as the Hubble Space Telescope and other space missions, the discovery of new planets becomes more possible. Various methods are used to detect planets, such as the transit technique, which observes the decrease in star light when a planet passes in front of it, and the radial velocity method which observes shifts in the star’s spectrum due to the planet’s gravitational force. One of the new planets that has been detected is an Earth-sized planet orbiting a star in the habitable zone. This discovery is very encouraging because it provides an opportunity for further research regarding the potential for life. Planets in nearby galaxies are usually made of the same elements as planets in our solar system, consisting of gas, rock and ice. By finding them, scientists can gain more information about how planets form and interact with their star systems. This article underscores the importance of also studying the new planet’s atmosphere, given the possibility of supporting life. The existence of new planets could also affect our understanding of the dynamics of the galaxy as a whole. Additional observations via infrared methods help astronomers identify planets that are more difficult to see. The existence of areas in Andromeda, which have a higher concentration of stars, increases the chances of discovering new planets. Computer simulations and theoretical models are now helping scientists visualize the possibility of planet formation in galaxies like Andromeda. This research has shown that not only stars, but also free planets—those not tied to stars—can be discovered. This knowledge broadens our astronomical horizons by questioning the concept of life’s ‘home’. International collaboration is also key to this research; Astronomers from various countries exchange data and the latest discoveries. These efforts led to the development of new, more efficient and reliable methods for searching for new planets. With these steps, the discovery of new planets in nearby galaxies is not just a scientific achievement, but also enriches our understanding of our place in the universe. Additionally, educational programs focused on astrobiology and exoplanets are becoming increasingly popular, encouraging a new generation of scientists to get involved in these discoveries. Student involvement in astronomy projects often provides unique and innovative perspectives. Further exploration of new planets in nearby galaxies promises deeper discoveries about the future of space exploration. Progress was felt in the accumulation of data, with astrophysics and astronomy becoming increasingly intertwined. With each new planet discovered, new questions are created, challenges to be solved, and opportunities to test existing theories. A multidisciplinary approach makes this search more dynamic and exciting, ensuring that we continue to uncover the mysteries of a universe that may still hold many secrets.
