Located in the galaxy CAPERS-LRD-z9, the supermassive black hole likely formed 13.3 billion years ago, barely 500 million years after the big bang.
But recent discoveries by the James Webb Space Telescope (JWST) mean we could find many similar black holes lurking inside so-called Little Red Dots, or LRDs.
“When looking for black holes, this is about as far back as you can practically go.
As it falls into a black hole, gas moving away from Earth’s perspective is stretched into redder wavelengths, while the gas moving towards the planet compresses into blue waves.
That makes it particularly supermassive even when compared to other supermassive black holes.
