James Webb Telescope Discovers Earth-Sized Exoplanet with Water Vapor

The James Webb Space Telescope has made a historic discovery of an Earth-sized exoplanet with water vapor in its atmosphere. The planet, designated K2-18b, is located 120 light-years away and orbits within the habitable zone of its star. This marks the first time water has been detected in the atmosphere of an exoplanet of this size. The discovery raises exciting possibilities about the potential for life beyond Earth and demonstrates the incredible capabilities of the Webb telescope in studying distant worlds.
