Nasa has released an image of far-flung galaxies as they were 13bn years ago, the first glimpse from the most powerful telescope ever launched into space, which promises to reshape our understanding of the dawn of the universe.
The small slice of the universe, called SMACS 0723, has been captured in sharp detail by the James Webb space telescope (JWST), showing that particular cluster as it was 4.6bn years ago, as well as the light from many different twinkling galaxies which are among the oldest in the universe. Joe Biden, who unveiled the image at a White House event, called the moment “historic” and said it provided “a new window into the history of our universe”.
