Euclid just lit up the first 670 million years of the Universe with a fresh crop of record-age quasars—and doubled the early tally to prove it happened.
Story Highlights
- Euclid spotted quasars from 670 million years after the Big Bang, matching or nudging the record.
- The find roughly doubles known early-universe quasars, expanding the sample fast.
- Specific redshifts and IDs await full papers, leaving room for careful follow-up.
- If confirmed, the haul pressures theories of how black holes grew so fast.
Euclid expands the frontier of the first billion years
The European Space Agency’s Euclid telescope scanned wide fields and flagged quasars from the Universe’s first 670 million years. That places them at the edge of the observable dawn, where light struggled through fresh hydrogen fog.
Media reports say the count of these ancient beacons has now doubled relative to earlier surveys. A larger sample gives astronomers better odds to sort patterns from noise. It also moves this science beyond one-off trophies toward population studies.
Quasars mark the glow from matter falling into supermassive black holes. They are bright enough to punch through space and time like cosmic lighthouses. Before Euclid, the standout was quasar J0313-1806.
It shone when the Universe was also about 670 million years old and hosted a black hole of about 1.6 billion solar masses. That object forced hard questions. How can a black hole get so big, so fast, with so little time to feed? Euclid’s new batch will sharpen those questions.
What “oldest” means—and why words matter
Reporters call these “the oldest quasars” found so far. That can mean they are the same age as the earlier record or a hair older. The present coverage does not list final redshift values or formal quasar names for Euclid’s finds.
Without that, the safest reading is “newly discovered examples at record age,” not “older than all before.” J0313-1806 set the bar at this age window, and it remains a key benchmark. Accurate labels maintain high trust while the data pipeline completes the job.
Euclid is built to map dark energy by surveying huge swaths of sky in visible and infrared light. That strength—wide and deep coverage—also makes it a finder of rare things.
Spot many targets first, then call in heavy spectroscopic tools to lock down distances. That two-step flow matches how modern astronomy works at scale. When the official releases post full redshifts and IDs, any “oldest” claim can move from headline hype to hard fact.
Why doubling the early sample changes the game
A doubled early-universe quasar count cuts the guesswork. One extreme outlier can mislead. Dozens start to map the terrain. Scientists can compare brightness, black hole mass, host galaxy dust, and surrounding gas.
The more objects we plot, the more we see trends and rule out flukes. If several quasars are at this age, then fast black hole growth was not a rare fluke. It was a feature of early cosmic life that theories must explain on a cosmic scale.
The Euclid space telescope has spotted the oldest quasars ever discovered — from when the universe was just 670 million years old, only 5% of its current age .

The most practical tests now are clear. First, confirm exact redshifts with independent telescopes. The James Webb Space Telescope and large ground observatories can pin the numbers that settle the age debate. Second, weigh the black holes.
Mass estimates, even with some error, decide which growth paths make sense. Third, check the host galaxies. Star formation rates and dust content tell us how busy these systems were while the black holes grew. Each step pushes hype toward history.
What this means for common sense and the public square
The facts at hand support a simple line: Euclid found very early quasars and likely doubled the count of such objects. The previous record was set at the same age by J0313-1806, which still frames the argument.
Strong claims must be backed by strong data. Until Euclid posts the quasar IDs and redshifts, the smart stance is firm but modest. Celebrate the haul. Demand the numbers. That balance signals respect for evidence and shields public trust from buzzword fatigue.
The big picture stays compelling even if “oldest” later becomes “tied for oldest.” More early quasars change how we think the first structures formed. Giant black holes did not wait their turn. They arrived early and changed their neighborhoods fast.
Euclid’s wide survey strategy is paying off, and the next set of spectroscopic locks will tell us how far the record moves. For now, the message is clear: the cosmic dawn just got brighter, busier, and harder to ignore.
