Euclid just peered back to when the universe was a cosmic toddler and found monsters already fully grown.
Story Snapshot
- Euclid discovered 31 blazing quasars from when the universe was only about 670 million years old.
- These objects rival the previous record quasar J0313-1806, long held as the earliest known.
- The find doubles the known population of such early quasars and challenges ideas of how fast black holes can grow.
- Hype about “oldest ever” meets a hard truth: the data is stunning, but the fine print really matters.
Euclid’s extreme time machine view of the young universe
The European Space Agency’s Euclid space telescope was built to map dark energy and dark matter, yet it just delivered something far more gripping for most people: a direct look at the universe when it was barely 5 percent of its present age, already hosting some of the brightest known beacons in the cosmos.
These 31 quasars shine with the light of about a trillion Suns, powered by gigantic black holes gulping matter near the dawn of galaxies.

Each quasar Euclid picked out is so far away that its light began traveling toward us around 670 million years after the Big Bang. For a sense of scale, the universe today is about 13.8 billion years old, so Euclid is sampling a slice of the universe when stars and galaxies had only recently emerged from the cosmic “dark ages”.
For 40-plus readers who remember growing up with grainy Hubble images, this is the same game, but played on hard mode, farther and earlier than ever.
How these quasars reset, and complicate, the cosmic record
Before Euclid’s announcement, the headline holder was quasar J0313-1806, discovered using telescopes in Hawaii and announced in 2021 as the most distant quasar known.
That object also dates to about 670 million years after the Big Bang and hosts a black hole with a mass roughly 1.6 billion times that of the Sun. Euclid’s new quasars match that cosmic era, and European Space Agency materials and follow-up coverage describe them as the “most ancient” and “oldest” quasars now known.
Here is the subtle wrinkle that careful readers should not miss. Being “oldest” in astronomy almost always comes down to tiny differences in redshift, which is how much the universe’s expansion has stretched the light. J0313-1806 sits at redshift 7.64.
Euclid’s public write-ups discuss the 670-million-year age but do not yet publish corresponding precise redshift values for each quasar in an easy-to-read form.
That silence does not mean the claim is false, but it does mean the record is based more on press framing than on a widely digested technical paper.
What Euclid’s discovery really tells us about black holes at cosmic dawn
Labels aside, the scientific punch is clear: by doubling the number of known quasars at these extreme early times, Euclid makes it much harder to see them as rare flukes.
James Webb Space Telescope follow-up of other early quasars has already shown that these beasts look shockingly normal, with black holes and feeding disks that resemble those seen billions of years later.
That pattern suggests supermassive black holes did not slowly grow from dead stars but instead started out large, likely from the direct collapse of massive gas clouds.
If the same “mature” quasars appear again and again so early, then the laws that build galaxies and black holes were in full force almost as soon as the universe allowed them. That picture fits a universe that is orderly and predictable, even when the details still stretch our current computer models.
Media hype, funding incentives, and why records keep getting “broken”
A familiar pattern in modern astronomy is at work here. Big missions like Euclid, the James Webb Space Telescope, and observatories such as the Vera C. Rubin are expensive and publicly funded.
Their teams have every incentive to highlight “record-breaking” discoveries, which grab headlines and help justify budgets. Reports of “most distant” or “oldest” objects often arrive through press releases and media stories before the full technical checks are finished.
Paris, France—The Euclid space telescope has spotted the oldest quasars—the brightest objects in the universe—ever discovered, deepening a cosmic mystery that has been puzzling scientists.

Past cases with early galaxies and black holes have shown that later, more careful measurements can nudge ages and redshifts down, turning “new oldest ever” into “another example at the same era”. That does not make the science fake, but it does argue for some healthy skepticism from readers.
The safer takeaway here is not that Euclid beat J0313-1806 by a clear margin, but that we now see a crowded zoo of giant black holes lighting up the universe’s first few hundred million years.
Why this matters beyond record chasing
Euclid’s quasar haul gives astronomers fresh targets to test deep questions about how fast black holes grow and how early galaxies evolve. Follow-up observations with the James Webb Space Telescope and ground-based telescopes will measure the masses of these black holes, map their host galaxies, and examine the gas around them.
If the hosts turn out to be normal-looking galaxies, that would support the idea that large structures form quickly and smoothly, not in a chaotic burst.
For non-scientists, the deeper message is that our picture of the universe’s beginning is becoming more detailed, not less. We now have dozens of bright beacons lighting up a time when the first stars were still new.
That reality should build trust in the basic story of cosmic history even as experts debate who holds this week’s “oldest” trophy. The universe does not care about our records. It simply keeps revealing how quickly it got complicated.
