Potential Water-Ice Clouds On A Jupiter-like Planet, A Step Toward Finding Them On Earth-like Worlds

They might ruin a sunny day, but clouds are a key part of what makes Earth home.

Scientists stunned as JWST finds ice clouds on a giant alien planet

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 Telescope, they found less ammonia than expected—likely hidden by thick, patchy clouds. The finding reveals new layers of complexity in giant planets and shows how much we still have to learn.
