Astronomers Find a Potentially Habitable Super-Earth Just 25 Light-Years Away

Astronomers have identified GJ 3378b, a super-Earth roughly twice the size of our planet, orbiting within the habitable zone of a star just 25 light-years away. The planet receives about 90 percent of the stellar radiation Earth gets from the sun, making it one of the closest potentially habitable worlds ever found. It was detected using the Habitable-zone Planet Finder in Texas and the NEID Spectrometer in Arizona, and the discovery is published in The Astrophysical Journal.
