James Webb has found evidence for thick water-ice clouds on Epsilon Indi Ab, one of the closest Jupiter-like worlds we can study directly — a discovery that didn’t overturn every atmospheric model, but exposed how many of them had been leaving out the very thing now shaping the planet’s sky.

The James Webb Space Telescope has found evidence for thick water-ice clouds high in the atmosphere of Epsilon Indi Ab, one of the closest Jupiter-like worlds we can study directly.

What it did was quieter and, in its way, more useful: it exposed how many [...] The post James Webb has found evidence for thick water-ice clouds on Epsilon Indi Ab, one of the closest Jupiter-like worlds we can study directly — a discovery that did
