Distant exoplanets may be hiding water beyond Webb Telescope's reach: Study

Scientists at the University of Chicago found that distant mini- or sub-Neptune exoplanets may contain far more water than their atmospheres reveal. Using a new simulation tool, ATHENAIA, researchers studied the exoplanet TOI-270 d and concluded its visible atmosphere could be hiding a much larger water-rich interior beyond the James Webb Space Telescope's current observational reach.
