Un equipo de astrónomos utilizó el Telescopio Espacial James Webb para estudiar la atmósfera de WASP-94A b, un gigante gaseoso con anclaje mareal situado a 690 años luz de distancia. Las observaciones revelaron mañanas nubladas y tardes despejadas en el planeta. Los resultados fueron publicados en la revista Science.

Un equipo dirigido por Sagnick Mukherjee en la Universidad Johns Hopkins empleó espectroscopia resuelta en el limbo con el instrumento NIRISS del JWST. Los investigadores separaron las señales de transmisión de los bordes matutinos y vespertinos durante el tránsito del planeta, lo que permitió descubrir aerosoles a gran altitud en el lado matutino y vapor de agua en el lado vespertino.

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.
