PARIS: The James Webb space telescope has discovered the oldest black hole ever detected, which was thriving so soon after the Big Bang that it challenges our understanding of how these celestial behemoths form, astronomers said on Wednesday.
The black hole was vigorously gobbling up its host galaxy just 430 million years after the birth of the universe during a period called the cosmic dawn, according to a study in the journal Nature. That makes it 200 million years older than any other massive black hole ever observed, study co-author and Cambridge University astronomer Jan Scholtz said.
