Exoplanet in habitable zone may still be uninhabitable

A newly discussed exoplanet sits within its star's habitable zone, but scientists caution it lies near the so-called cosmic shoreline. This means its host star may have stripped away the planet's atmosphere through intense radiation, leaving it unable to hold liquid water despite orbiting at a seemingly habitable distance. The case highlights how the habitable zone alone is not enough to judge a planet's prospects for life, and atmospheric loss must also be considered.
Why now: Astronomy communicators are highlighting that being in the habitable zone does not guarantee habitability.
