What can clouds teach astronomers about an exoplanet’s atmospheric characteristics? This is what a recent study published in ...

James Webb Space Telescope exoplanet weather observation confirms the first daily cloud cycle ever detected outside our solar system, revealing that a decade of hot Jupiter atmospheric composition ...

WASP-94A b, a hot Jupiter nearly 700 light-years away, builds mineral cloud cover each morning and loses it by evening. This ...

Astronomers using the James Webb Space Telescope’s Mid-Infrared Instrument have determined that the rocky exoplanet LHS 3844 b, located 48.5 light-years away, has a dark, atmosphere-free surface ...

A planet that is about the size of Saturn, but with a temperature more like Earth's, has an atmosphere rich in methane, ...

Scientists have discovered unexpected water-ice clouds on a distant, Jupiter-like exoplanet, challenging current atmospheric models. By directly imaging Epsilon Indi Ab with the James Webb Space ...

The light from LHS 3844 b does not suggest oceans, clouds, or even air. What it points to instead is a dark, battered surface. This surface may have more in common with Mercury or the Moon than with ...

A team of astronomers led by Elisabeth Matthews at the Max Planck Institute for Astronomy (MPIA) has made a discovery that highlights the limits of most current models of exoplanet atmospheres: ...

Despite being hotter than Earth, the exoplanet's temperature is mild by giant planet standards.

A strange “forbidden” planet spotted by the James Webb Space Telescope is turning planetary science on its head. TOI-5205 b, a Jupiter-sized world orbiting a small, cool star, has an atmosphere ...

JWST studied a massive Jupiter-like exoplanet's atmosphere, finding surprising water-ice clouds that simpler models missed - a key test run for future Earth-like world searches. The way the ...
