The Hubble Space Telescope once pointed at a seemingly empty patch of sky for 11 days. What it found changed everything. The image, now known as the Hubble Ultra-Deep Field, revealed over 10,000 galaxies packed into a space smaller than the moon in the sky. It showed that even the darkest parts of the universe are filled with ancient light, billions of galaxies hiding in plain sight. It made us realize we're far from alone in the vast structure of the cosmos. | Auto Viral
