How can a telescope see galaxies beyond the universe’s horizon?

  • The James Webb Space Telescope (JWST) has observed some of the most distant galaxies ever seen
  • The universe’s expansion allows us to see galaxies that are further away than the age of the universe would suggest
  • JADES-GS-z14-0, the most distant galaxy ever seen, is located 33.8 billion light-years away
  • The expansion of the universe allows light from distant galaxies to reach us in a shorter time
  • The cosmological horizon is the maximum distance from which light could have traveled to us in the age of the universe

The James Webb Space Telescope (JWST) has revolutionized astronomy by observing some of the most distant galaxies ever seen. Despite the age of the universe being 13.8 billion years, the JWST can see galaxies that are further away than this. This is possible due to the expansion of the universe, which allows light from distant galaxies to reach us in a shorter time. For example, JADES-GS-z14-0, the most distant galaxy ever seen, is located 33.8 billion light-years away. The cosmological horizon, which is the maximum distance from which light could have traveled to us in the age of the universe, is around 46.1 billion light-years away. This means that JADES-GS-z14-0 is within this horizon. The expansion of the universe has allowed us to see galaxies that would otherwise be beyond our reach. The JWST continues to explore the cosmos and provide valuable insights into the origins of the universe.·
