Super Earths Explained: Why They Could Outshine Earth
Are we actually residing on the greatest possible world for life—just a good one by cosmic standards? In this illuminating episode of Science Unlocked, we consider the amazing potential that super Earths—giant, terrestrial worlds three to ten times larger than Earth—may be far more livable than our home blue globe. These distant worlds are endowed with strong magnetic fields, dense atmospheres, more intense gravity, and stable geological activity that may sustain life for another billion years or more beyond what Earth can. With more of these planets being found using advanced telescopes such as Kepler and the James Webb Space Telescope, super Earths are becoming frontrunners in the hunt for life outside our solar system. From the hydrogen-rich ocean planet of K2-18b to Trappist-1e's theoretically habitable zone, these are not just hypotheticals with promise—these are actual locations with actual promise. Follow along with us as we explore the science of why super Earths may not only exist—but may be superior.
