Kickin’ it in the Habitable

A team of astronomers from Penn State led by Ravi Kumar Kopparapu and Ramses Ramírez, also PHL collaborators, announced a redefinition of the classical stellar habitable zone. Their study has strong implications on how we search and study potentially habitable exoplanets.
The main conclusion of their study is that the habitable zones are actually farther away from the stars than previously thought. Interestingly, Earth appears to be now situated at the very inner edge of the habitable zone.
The new study builds on the previous work of James Kasting, Evan Pugh Professor of Geo-sciences at Penn State, also one of the co-authors. Currently, all definitions of the habitable zone were based on Dr. Kasting’s pioneering work.
