JWST spies more black holes than astronomers predicted

Over the past year, the James Webb Space Telescope (JWST) has outstripped astronomers’ expectations in terms of the number of black holes it has observed. JWST captured roughly ten times as many faint black holes — which hail from a time when the Universe was about 1 billion to 1.5 billion years old — as expected. The discovery could help scientists to probe questions about how black holes formed in the early Universe, and how they grow into cosmic vacuums that devour everything around them.
