Nearby Earth-Sized World in Red Dwarf’s Habitable Zone Prompts Life Talk
A reanalysis of exoplanet GJ 3378b, 25 light-years away, shows it has about twice Earth’s mass and lies in its red dwarf’s habitable zone, making it a strong nearby candidate for life-supporting conditions. Its atmosphere and pressure are still uncertain, and debates about red-dwarf habitability—along with potential tidal locking and stellar flares—mean more data are needed before confirming its ability to support life.
