  James Webb Telescope Finds Galaxies Nearly as Old as the Early Universe

  NASA’s James Webb Space Telescope has revealed early galaxies that appear almost as old as the universe itself. By analyzing 31 galaxies at high redshift, researchers estimated stellar ages of around 600 million years—close to the universe’s age at that epoch. One galaxy may even seem older than the universe, posing a potential challenge to t...

  James Webb Telescope Discovers Most Distant Galaxy From Just 300 Million Years After the Big Bang

  The James Webb Space Telescope has discovered the most distant galaxy ever observed, JADES-GS-z14-0, seen as it existed just 300 million years after the Big Bang. Its unexpected brightness and chemical complexity suggest rapid early star formation, challenging long-standing theories about how the first galaxies evolved in the early universe.
