Astrônomos utilizaram o Telescópio Espacial James Webb para estudar a atmosfera de WASP-94A b, um gigante gasoso com acoplamento de maré localizado a 690 anos-luz de distância. As observações revelaram manhãs nubladas e noites limpas no planeta. As descobertas foram publicadas na revista Science.

Uma equipe liderada por Sagnick Mukherjee, da Universidade Johns Hopkins, empregou espectroscopia de resolução de limbo com o instrumento NIRISS do JWST. Eles separaram os sinais de transmissão dos limbos da manhã e da tarde durante o trânsito do planeta, descobrindo aerossóis de alta altitude no lado da manhã e vapor d'água no lado da tarde.

JWST discovers water ice clouds on Jupiter-like exoplanet

Astronomers using the James Webb Space Telescope have detected thick water ice clouds on Epsilon Indi Ab, a cold gas giant resembling Jupiter. The finding, led by researchers at the Max Planck Institute for Astronomy, reveals less ammonia than expected in the planet's atmosphere. This challenges existing models and advances techniques for studying distant worlds.

NASA's James Webb Space Telescope has observed an unusually thick haze on the exoplanet Kepler-51d, obscuring its atmospheric composition. This super-puff planet, part of a rare low-density system around the star Kepler-51, challenges standard models of planetary formation. The findings, led by Penn State researchers, were published on March 16 in the Astronomical Journal.
