The James Webb Space Telescope (JWST) has discovered what appears to be the two earliest, most distant galaxies in the known universe. These galaxies date back to just 300 million years after the Big Bang, LiveScience reported on Friday (May 31), citing a research paper.
This galaxy duobroke the records set by another pair of galaxies discovered by the JWST in 2023,which date back to roughly 330 million years after the birth of the universe. Researchers spotted the galaxies in a region of space known as the Hubble Ultra Deep Field.

The galaxies have been namedJADES-GS-z14-0 and JADES-GS-z14-1. LiveScience reported that both galaxies were also unusually large for such an early time in cosmic history.
The latest discoveryadds to a mounting pile of evidence thatthe earliest galaxies in the universe grew up much faster than leading theories of cosmology predict to be possible.
"It is stunning that the Universe can make such a galaxy in only 300 million years," Professor Stefano Carniani from theScuola Normale Superiore said in a statement.
The larger of the two galaxies
JADES-GS-z14-0is larger thanJADES-GS-z14-1. Researchers said that the impressive size and brightnessof JADES-GS-z14-0 is likely being fuelledby young and actively forming stars, rather than a supermassive black hole.
The team also noted that JWST could have detected the galaxy even if its light was 10 times fainter than what was observed.
