MIT Scientists Solve Mystery of Rare 'Odd Couple' Planetary System

One hundred ninety light-years away, a planetary system has quietly defied what astronomers believed possible — a small, atmosphere-rich world orbiting closer to its star than a massive hot Jupiter, a configuration long thought to be gravitationally forbidden. Using the James Webb Space Telescope, MIT researchers have now read the chemistry of that inner world's skies, and the molecules found there tell a story of distant origins and slow, patient migration. The discovery does not merely explain one unusual system; it confirms a pathway of planetary formation that reshapes how we understand th
