Astronomers have discovered the largest rocky planet yet, and its existence has profound implications for our understanding of the early universe and the potential for extraterrestrial life. Kepler-10c, which was spotted by NASA’s Kepler space telescope, has a diameter of roughly 18,000 miles—more than twice that of Earth —prompting scientists to create a new class of planets, dubbed “mega-Earths.”The body’s […]
