The James Webb Telescope found the 'Sleepy' galaxy: it flared with stars at the dawn of the universe, then fell asleep for hundreds of millions of years. Now scientists think bright early galaxies don't have to become giants—some turn into 'dwindling embers'.
🎯 By today, Sleepy would have become so dim that no modern telescope could see it—half a billion years of slumber have made it nearly invisible.
