New discovery promises to reveal hidden black holes across the universe

Scientists have detected radio signals from hot gas surrounding a supermassive black hole that existed 12.9 billion years ago .

This finding is the closest look ever at hot molecular gas near a black hole from such an early time in the universe.

The study suggests that many black holes may remain hidden behind dust but could be uncovered by this new observational approach.

The discovery had significant implications for our understanding of black holes in the early universe.
