Is it true that planets outside our solar system could support life?
Unclear. The retrieved sources only partially address the claim: one NASA page notes exoplanet K2-18 b has water and temperatures that could support life, and a dynamical study identifies habitable-zone candidates in the 47 UMa system. Other items treat life beyond the solar system as a possibility under investigation rather than an established fact.
