A little over six months ago, NASA's James Webb Space Telescope (JWST) delivered its first photographs, dazzling the world as it revealed the cosmos in glorious technicolor. The first picture transmitted in July showed a galaxy cluster located in the Southern hemisphere sky, 5.12 billion light years from Earth. In the words of US president Joe Biden, it represented "the deepest and sharpest infrared image of the distant universe" taken by humanity so far.
