Water vapor has been discovered in the atmosphere of exoplanet K2-18b. -- Story: Water Vapor Detected in Atmosphere of an Alien World Nearly Twice the Size of Earth: https://www.space.com/water-vapor-in-atmosphere-of-alien-planet-k2-18b.html

The alien world orbits a red dwarf star which has lead to speculation that it is exposed to higher levels of radiation than Earth. In the future, studies using NASA's James Webb Space Telescope and other next generation telescopes could reveal more about the planet.
