Exoplanets are planets that exist outside of our solar system, orbiting stars other than the Sun. Research in this area focuses on discovering and studying these distant worlds, with the goal of better understanding the diversity of planetary systems in our galaxy and potentially identifying habitable or Earth-like planets. Scientists use a variety of methods to detect exoplanets, including transit photometry, radial velocity measurements, and direct imaging. The study of exoplanets has revolutionized our understanding of planetary formation and evolution, and has raised intriguing questions about the possibility of life beyond Earth.
