The Webb telescope peered into the young universe and spotted a quasar grinding dust into the tiniest particles. Such 'dust factories' could have helped galaxies quickly stock up on material for new stars.
🎯 The light from this quasar traveled 12.5 billion years to reach the telescope. We see it as it was just 1.3 billion years after the Big Bang.
