NASA Missions Uncover a Diverse Galaxy of Super-Earths, Raising New Questions About Planetary Evolution

Super-Earths are among the most common planets in the galaxy, yet none exist in our solar system. Larger than Earth but smaller than Neptune, they range from ocean-covered worlds to scorched, atmosphere-less rocks. Some orbit within habitable zones, making them prime candidates for life. NASA’s Kepler and TESS missions, along with upcoming telescopes like JWST, are unraveling their mysteries—exploring their atmospheres, compositions, and potential to host life. These discoveries could reshape our understanding of planet formation and the conditions that make a world truly habitable.
