GJ 238 b is a newly discovered world orbiting the star GJ 238, revealed to us in 2024 thanks to the keen eyes of the Transiting Exoplanet Survey Satellite (TESS). This space-based planet-hunter detected GJ 238 b as it charmingly passed in front of its star, creating tiny dips in starlight that gave away its presence. Though still a fresh find, this exoplanet sparks curiosity and wonder about what its skies and surface might be like. As part of the vibrant neighborhood monitored by TESS, GJ 238 b invites us to dream about the diverse worlds waiting to be explored beyond our solar system, highlighting how our cosmic backyard is far more dynamic—and delightful—than one might expect.
