“三体”星系，有新发现！

Core Viewpoint - An international research team has observed a candidate exoplanet located in the habitable zone of the Alpha Centauri star system using the James Webb Space Telescope, marking a significant advancement in the search for potentially habitable worlds beyond Earth [2]. Summary by Sections Discovery of the Exoplanet - The candidate exoplanet is a gas giant orbiting the A star of the Alpha Centauri system, which is approximately 4 light-years away from Earth and has a star similar to the Sun [2]. - This observation is notable as it is the first time a planet in the habitable zone has been directly imaged, contrasting with the typical indirect methods used to discover exoplanets [2][3]. Future Research and Implications - The research team plans to conduct further observations to confirm the findings, which could provide insights into the habitability of potential moons orbiting the gas giant [2]. - Although the gas giant itself is unlikely to support life, its presence raises exciting possibilities for the habitability of its satellites [2].
