Utilizing the James Webb Space Telescope, astronomers have investigated the atmosphere of a temperate Saturn-sized exoplanet called TOI-199b. Located approximately 330 light-years away from Earth, TOI-199b is a gas giant that is not as hot as other similar planets, but exhibits near-Earth-like temperatures. The planet's atmosphere has been found to contain methane, along with hints of ammonia and carbon dioxide.
This marks the first time researchers have closely examined the atmosphere of a temperate gas giant, providing valuable insights into the formation and evolution of such planets.
