Euclid telescope discovers the most ancient quasars ever observed
Europe's Euclid space telescope has found 31 of the most ancient quasars known, including the two earliest ever observed, dating to when the Universe was just 670 million years old. The results were published in Astronomy & Astrophysics and reported by ESA and NASA Science.
The European Space Agency's Euclid space telescope has discovered 31 of the most ancient quasars ever found, including the two earliest yet observed, shining when the Universe was only 670 million years old, about five percent of its current age. The most distant sits at a redshift of 7.77, breaking the previous 2021 record of 7.64. Quasars are galaxy cores powered by supermassive black holes, blazing with the light of a trillion Suns. Euclid found more of these ancient objects in a single year than astronomers had gathered over a decade, using data from the Euclid Wide Survey that will eventually cover more than a third of the sky.
