Astrônomos identificaram um raro sistema planetário a 190 anos-luz da Terra, apresentando um Júpiter quente que compartilha sua órbita com um mini-Netuno mais próximo da estrela. Essa configuração já foi considerada quase impossível. Novas observações do Telescópio Espacial James Webb fornecem novas percepções sobre como os planetas se formaram.

O sistema, centrado na estrela TOI-1130, foi detectado pela primeira vez em 2020 usando dados do Transiting Exoplanet Survey Satellite da NASA. O mini-Netuno completa uma órbita a cada quatro dias, enquanto o Júpiter quente leva oito dias. Os pesquisadores observaram que Júpiters quentes normalmente não possuem companheiros próximos devido à sua forte influência gravitacional.

Astronomers using the James Webb Space Telescope have detected an unusually metal-poor atmosphere on the Jupiter-sized exoplanet TOI-5205 b, which orbits a small, cool star. The planet's atmospheric metallicity is lower than that of its host star, challenging theories of giant planet formation. The findings come from a study led by researchers at NASA's Goddard Space Flight Center and Carnegie Science.

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.
