The brief
The European Space Agency’s Euclid telescope has identified the most ancient quasars known, dating back to the universe’s cosmic dawn. These supermassive black holes, emitting intense radiation, were detected in regions previously unexplored for such early phenomena. The discovery includes 31 newly pinpointed quasars, with some appearing just 500–700 million years after the Big Bang.
Coverage highlights Euclid’s unprecedented ability to map distant objects with high precision, surpassing earlier observations by the Subaru Telescope and other instruments. Outlets including *DW.com*, *CBS News*, and *Phys.org* emphasize the quasars’ unexpected brightness and rapid formation, calling the findings ‘perplexing’ and challenging existing models of galaxy evolution. The European Space Agency has published coordinates for the quasars, inviting further study.
Next steps focus on confirming the quasars’ ages through follow-up spectroscopy and integrating data with other telescopes like JWST. Researchers may also investigate whether these objects defy current theories on black hole growth or early star formation. Coverage does not yet specify timelines for additional discoveries or collaborations.

Quick answers
What is a quasar?
A quasar is an extremely luminous active galactic nucleus powered by a supermassive black hole accreting matter, emitting vast energy across the electromagnetic spectrum.
How old are these newly discovered quasars?
Coverage indicates they date to approximately 500–700 million years after the Big Bang, making them the oldest quasars ever observed.
Which telescope detected these quasars?
The European Space Agency’s Euclid telescope identified the quasars, with supporting data from the Subaru Telescope.
