A nearby super-Earth may be one of the best chances yet to search for life beyond our solar system. A newly detected super-Earth just 20 light-years away is giving scientists one of the most promising chances yet to search for life beyond our solar system. The discovery of the exoplanet orbiting in the habitable zone of its star was made possible by advanced spectrographs designed at Penn State and by decades of observations from telescopes around the world.

A possible “super-Earth” located less than 20 light-years from Earth is giving researchers renewed optimism in the search for planets that might host life. The newly identified world, GJ 251 c, earned its “super-Earth” label because current data indicate it is almost four times the mass of Earth and is likely a rocky planet.

“We look for these types of planets because they are our best chance at finding life elsewhere,” said Suvrath Mahadevan, the Verne M. Willaman Professor of Astronomy at Penn State and co-author of a recent paper in The Astronomical Journal. “The exoplanet is in the habitable or the ‘Goldilocks Zone,’ the right distance from its star that liquid water could exist on its surface, if it has the right atmosphere.”
