Webb spots a supermassive black hole in this early universe growing at an unusual rate

SMRTR summary

Using the James Webb Space Telescope, astronomers discovered a supermassive black hole in galaxy CANUCS-LRD-z8.6 that is growing unusually fast, just 570 million years after the Big Bang. The black hole's massive size defies established understanding that supermassive black holes and their host galaxies should grow at similar rates. This discovery challenges current theories about black hole formation and growth in the early universe, prompting researchers to plan additional observations to better understand this phenomenon.
