Summary

Story summary

The James Webb Space Telescope (JWST) has identified the galaxy GHZ2, hosting a potentially supermassive black hole, 350 million years after the Big Bang.
The discovery raises questions about how supermassive black holes form so early.
Observations show GHZ2 exhibits high-ionization emission lines, which suggest an actively feeding black hole, though some indicators of an active galactic nucleus are absent.
Further JWST observations are planned to confirm AGN activity.
