  • Analysis of data from multiple instruments reveals a giant exoplanet in orbit around the 0.2-solar-mass star TOI-6894. The existence of this exoplanetary system challenges assumptions about planet formation and it is an excellent target for atmospheric characterization.

  • Saturn-mass exoplanet HD 149026b has an atmospheric metallicity 59–276 times solar, which is greater than Saturn’s atmospheric metallicity of roughly 7.5 times solar and more correlated with bulk metallicity than planet mass.

  • A comprehensive study of the Kepler-138 system reveals the twin nature of Kepler-138 c and d and the presence of a fourth planet. Remarkably, the warm-temperate planet Kepler-138 d is probably composed of 50% volatiles by volume, indicative of a water world, rather than a rocky world, despite its small ~1.5 R⊕ size.
