"Webb Telescope to Probe Habitable Exoplanet"

The James Webb Space Telescope could determine whether a rocky exoplanet, LP 890-9c, located near the inner edge of its star's habitable zone, is habitable or not. The exoplanet's position in its planetary system is analogous to Venus' location in our solar system, which is also at the inner edge of the habitable zone. The telescope could distinguish between different climatic and atmospheric states that LP 890-9c could be in, and how long a rocky planet can maintain habitability when it starts to get hot. The findings could teach us about the fate of our own planet, Earth, as the sun ages and grows brighter and warmer.
