 Astronomers using the  James Webb Space Telescope (JWST) have discovered the four most distant galaxies ever observed, located 13 billion light-years from Earth. This means astronomers are seeing what galaxies looked like in the infancy of our universe, now about 14 billion years old, 300 to 500 million years after the Big Bang, according to two new   .(opens in new tab) studies(opens in new tab)   Published April 4 in the journal Nature Astronomy.

"The Frontier Is Moving Around Every Month,"  Pieter van Dokkum(opens in new tab), a professor of astronomy at Yale University who was not involved in the study,  said in a comment.(opens in new tab)Published in Nature Astronomy. "There are now only 300 million years of the unaltered history of the universe between these galaxies and the Big Bang," van Dokkum said.

This may sound like familiar news, as several studies have recently   claimed the possible detection of old galaxies  using the JWST over the past few months. The four newly discovered galaxies are different, though – astronomers have indeed confirmed that these are ancient galaxies and not some other celestial body, or a near-galaxy disguised as a more distant one.
