Astronomers using the James Webb Space Telescope (JWST) have discovered two of the oldest and most distant galaxies in the known universe, dating to just 330 million years after the Big Bang.
These ancient objects — estimated to be the second and fourth most distant galaxies ever detected — fall just shy of the earliest known galaxy, named JADES-GS-z13-0, which was previously spotted by JWST at around 300 million years after the dawn of time. The light from all three of these immensely old galaxies traveled for more than 13 billion years to reach JWST's lens.
