๐ Habitable Super-Earth Found Just 25 Light-Years Away โ And It's Right on the Edge
A paper published June 30 in The Astrophysical Journal revised our picture of GJ 3378b โ a rocky world about 2.3 times Earth's mass orbiting in the habitable zone of its star, Gliese 3378, receiving roughly 90% of the solar radiation Earth gets from our Sun. At just 25 light-years away, it's one of the closest potentially life-friendly planets ever confirmed. The catch: it sits right on the "cosmic shoreline," the boundary where stellar radiation can strip a planet's atmosphere clean away. Does this world have what it takes to hold onto an atmosphere?
