James Webb Telescope Detects Water Vapor in Nearby Star System and Rocky Planet's Atmosphere.
TL;DR
The James Webb Space Telescope has detected hints of water vapor on a rocky exoplanet known as GJ 486 b, which orbits a red dwarf star. However, the water vapor could be on the star itself and not from the planet at all. Additional observations are needed to determine if the planet has an atmosphere or if the water vapor is from the star. If the water vapor is associated with the planet, that would indicate that it has an atmosphere despite its scorching temperature and close proximity to its star.
