Nearby rocky super-Earth found in habitable zone around a red dwarf

Astronomers refined the mass and orbit of the nearby exoplanet GJ 3378b, a rocky super-Earth about 2.3 Earth masses that orbits a red dwarf every 21 days at roughly 25 light-years away, placing it in the habitable zone where liquid water could exist if it retains an atmosphere; however, stellar winds from the red dwarf may strip the atmosphere, and the planet does not transit, limiting atmospheric study and pushing biosignature confirmation to future observatories such as NASA's Habitable Worlds Observatory planned for the 2040s.
