"Super-Earth" exoplanets may have an in-built way to protect themselves from harmful radiation, giving any potential life on such worlds a better chance of surviving, according to recent research.
Super-Earths, worlds larger than Earth but smaller than Neptune, are among the most commonly detected types of extrasolar planets, or exoplanets, in the Milky Way. Because many have been found within their stars' habitable zones — regions where liquid water could exist and, thus, potentially support life — scientists have increasingly focused on whether these planets can sustain life-friendly conditions over billions of years.
