New “Super-Earth” Found in the Habitable Zone
Season 2 Episode 260
Astronomers have discovered GJ 251 c, a “super-Earth” nearly four times our planet’s mass, orbiting in its star’s habitable zone — the sweet spot for liquid water and possibly life. Using 20 years of data and tools like the Habitable-Zone Planet Finder, researchers from Penn State tracked the star’s subtle wobble to confirm the planet’s presence.
While we can’t yet study its atmosphere, future telescopes may reveal whether GJ 251 c holds signs of alien life.
