In March 2026 the European Space Agency's Euclid space telescope discovered 31 of the most ancient quasars ever found, more than doubling the number of quasars we know of that are so old. Two of these giant, dazzling, black hole-powered galaxy cores are older than any we’ve seen before. These cosmic elders shone with the light of a trillion Suns back when the Universe was 670 million years old – just 5% of its current age.
