A new study using the Keck Observatory reveals that giant planets can spin faster than more massive brown dwarfs, indicating that magnetic fields and formation processes play a key role in planetary rotation.
The James Webb Space Telescope has discovered a gas giant exoplanet, WASP-94A b, where rock clouds form in the morning and vanish by night.
New research indicates that supermassive black holes can render exoplanets uninhabitable by stripping away atmospheres and depleting ozone, even at vast distances.
Astronomers used the James Webb Space Telescope to analyze the super-Earth LHS 3844 b, finding it to be a dark, airless, rocky planet with a surface composition similar to basalt or Earth's mantle, likely shaped by space weathering.
The James Webb Space Telescope has found unexpected water-ice clouds on the exoplanet Epsilon Indi Ab, challenging current atmospheric models for gas giants.
