Summary

Story summary

Astronomers using the James Webb Space Telescope (JWST) confirmed a rapidly growing supermassive black hole in galaxy CANUCS-LRD-z8.6, seen 570 million years after the Big Bang.
The black hole weighs 100 million solar masses and is large for its host galaxy.
The finding challenges existing theories and suggests black holes formed and grew faster early in the Universe.
The team plans observations to study the galaxy’s properties and growth mechanisms.

History

Historical Context

The discovery of a 12 billion solar mass black hole in the galaxy SDSS J010013.02+280225.8 in 2015 challenged existing theories about black hole formation, suggesting they could form rapidly in the early universe. This finding aligns with the detection of similar black holes, like that in CANUCS-LRD-z8.6, indicating that supermassive black holes may have emerged much earlier than previously believed, reshaping our understanding of cosmic evolution.
