At the dawn of the Universe, just 1.2 billion years after the Big Bang, the James Webb Space Telescope found a supermassive black hole shrouded in dense cosmic dust. For the first time at such a distance, scientists measured the amount of dust by the light of oxygen — it dims the black hole's glow, like tinted glass. This is a key to understanding the rapid growth of the first giant holes.
🎯 Galactic dust is made of tiny carbon and silicate particles, like soot or sand, only a thousand times smaller than the width of a human hair.
