ESA and NASA/CSA released a James Webb Space Telescope Picture of the Month showing the galaxy cluster MACS J0454.1-0300, whose gravity lenses and magnifies galaxies from up to 800 million years after the Big Bang. The image shows hundreds of galaxies missing from the 2014 Hubble view, and some lensed knots are magnified more than 300 times.
