Euclid telescope discovers the 2 most ancient monster black holes in the universe ‪—‬ each brighter than a trillion suns

The ESA's Euclid space telescope has discovered 31 previously unknown quasars from the universe's earliest era, including the two oldest ever found, both shining with the light of a trillion suns just 670 million years after the Big Bang. These findings more than double the known quasars from that period, helping scientists understand how supermassive black holes grew so massive so quickly after the universe began.
