A team of astrophysicists have discovered the oldest galaxy ever observed, thanks to new pictures from the James Webb Space Telescope.


This article by Kiona Smith, writing for Inverse, makes the following points:
  • The galaxy, dubbed GLASS-z13, is 13.5 billion light years away.
  • The James Webb telescope saw the light from the galaxy as it looked just 300 million years after the Big Bang when the universe was still very young.
  • These new photos challenge critical ideas about what the early universe was like.
  • The James Webb also discovered another surprisingly bright young galaxy, GLASS-z11, in the same relatively small patch of sky.
  • Where astronomers previously only knew of one galaxy dating back to the first few hundred million years of the universe, now they know about three.
