Dating back just 300 million years after the Big Bang, the James Webb Space Telescope has spotted the two earliest most distant galaxies in the universe, according to Live Science.

This new space search breaks the records set by another pair of galaxies, which were discovered by JWST last year. These galaxies roughly date back to 330 million years after the birth of the universe. They further push back our understanding of cosmic dawn even further.

Besides being exceptionally old, the newly discovered galaxies named JADES-GS-z14-0 and JADES-GS-z14-1 are also unusually large for such an early time in cosmic history in addition to being exceptionally old, according to the discovery paper published May 28 to the preprint server arXiv.

"It is stunning that the Universe can make such a galaxy in only 300 million years," lead study author Stefano Carniani, who is also an assistant professor at the Scuola Normale Superiore in Pisa, said in a statement.
