Massive terrestrial planets, called “super-Earths,” are known to be common in the Milky Way. Now a Northwestern University astrophysicist and a University of Chicago geophysicist report the odds of these planets to be more Earth-like than previously thought as they’re likely to have both oceans and continent.
Nicolas B. Cowan and Dorian Abbot’s new model concludes that most tectonically active super-Earths, regardless of mass, store most of their water in the mantle and will have both oceans and exposed continents, enabling a stable climate such as Earth’s. Read the full article here.
