NASA's James Webb Space Telescope (JWST) has spotted four of the oldest galaxies seen to date. These galaxies formed just 400 million years, or even earlier, after the Big Bang, which took place 13.8 billion years ago. A paper on them, which is yet to be peer-reviewed, was presented at the Space Telescope Science Institute in Baltimore on December 12.
