This news article discusses how scientists are getting closer to finding an "Earth twin" among Venus-like exoplanets using the James Webb Space Telescope. A group of researchers has compiled the first paper on all known information about planets like Venus beyond our solar system. They have identified five exoplanets that are most likely to resemble Venus in terms of their radii, masses, densities, shapes of their orbits, and distances from their stars. These Venus-like planets are located in the Venus Zone, where planets are too hot for water but not hot enough to strip their atmosphere. The study aims to learn more about the past, present, and future of Venus to understand how the Earth could be affected. The Webb telescope will enable scientists to observe these exoplanets and determine their atmospheric composition. The observations may also reveal biosignature gases, indicating the presence of life. These findings may provide valuable insights into Earth's future and help scientists prevent the development of a runaway greenhouse climate like Venus.
