Astronomers have spent decades searching nearby stars for another Earth, and now they may have found one just 25 light-years away

Scientists have found GJ 3378b, a planet near Earth with potential for life. This exoplanet is twice Earth’s size and orbits within its star’s habitable zone. Researchers used ground-based instruments to update measurements of GJ 3378b’s mass. Future telescopes will study its atmosphere to confirm habitability and search for biosignatures. This discovery adds GJ 3378b to the list of promising nearby exoplanets.
