Nearby Super-Earth Could Harbor Life in Red Dwarf's Habitable Zone

A refined analysis places GJ 3378b at about 2.3 Earth masses with a 21‑day orbit, situating it in the habitable zone of a nearby red-dwarf star about 25 light‑years away. Detected with infrared radial velocities using the Habitable-zone Planet Finder on the Hobby‑Eberly Telescope, the discovery highlights red dwarfs as fertile ground for rocky, potentially life-bearing worlds, though stellar activity and a possibly thin atmosphere complicate habitability. Upcoming observatories like GMT, ELT, and the Habitable Worlds Observatory could enable direct observations and biosignature searches to assess its true habitability.
