The James Webb telescope hunted for a moon around a distant Jupiter. But instead of a clear signal, it caught a mystery: a slow brightness drift makes it hard to tell a moon from a starspot. The solution awaits in 2027.
🎯 The brightness drift is caused not by the star, but by the telescope itself: its camera warms and cools, flickering like a living heart.
🎬 The search for distant moons has long become real, yet still evokes scenes from 'Star Wars': somewhere out there, around gas giants, their own Endors could be hiding.
