Thanks to JWST's powerful technology, scientists could see features they've never seen before—like those patchy water-ice clouds that might even support certain life forms.
As researcher Elisabeth Matthews put it, "JWST is finally allowing us to study solar-system analog planets in detail. If we were aliens, several light years away, and looking back at the Sun, JWST is the first telescope that would allow us to study Jupiter in detail."
The team also noticed less ammonia gas than expected, suggesting current models of exoplanet atmospheres might need an update.
Basically, space just got a lot more interesting.
