Euclid Discovers Ancient Quasars
Analysis based on 10 articles · First reported Jul 06, 2026 · Last updated Jul 06, 2026
The discovery by the Euclid (spacecraft) telescope, operated by the International — European Space Agency, is a significant scientific breakthrough in astrophysics. While not directly impacting financial markets, it enhances the reputation of the involved scientific institutions and aerospace companies like Thales Alenia Space and Airbus — Airbus Defence and Space that contributed to the telescope's construction, potentially influencing future funding and contracts in the space industry.
The International — European Space Agency's Euclid (spacecraft) space telescope has discovered 31 of the most ancient quasars ever found, including the two earliest observed in cosmic history. These quasars, powered by supermassive black holes, shone with the light of a trillion Suns when the Universe was only 670 million years old. This finding, detailed in a paper by Peng Yang of Leiden University and published in Astronomy & Astrophysics, more than doubles the number of known ancient quasars and provides unprecedented insights into the early Universe, the formation of supermassive black holes, and the epoch of reionization. PSO J030947.49+271757.31 and collaborators conducted follow-up studies on one of these quasars, revealing its host galaxy's intense star formation. The mission's success highlights the advanced capabilities of the Euclid (spacecraft) telescope, built by contractors like Thales Alenia Space and Airbus — Airbus Defence and Space with contributions from United States — NASA.
