Astronomers have successfully analyzed the atmosphere of HAT-P-44 b, a gas giant similar in size and temperature to Saturn, located in a tight orbit around its star. Using the William Herschel Telescope, the team detected the chemical signature of sodium and found evidence of water vapor within the planet's envelope. The findings suggest the planet has a relatively clear atmosphere at high altitudes, free from thick clouds, and a chemical composition richer in heavy elements than our own Sun...
