NASA’s James Webb Space Telescope (JWST) has shattered the record for the most distant supermassive black hole ever observed. This ancient quasar, powered by the black hole, dates back to just 670 million years after the Big Bang – making it the earliest observed quasar currently known.
Ancient Quasar Marks Dawn of the First Supermassive Black Holes
Quasars are extremely luminous cores of distant massive galaxies that contain actively “feeding” supermassive black holes. As interstellar gas and dust fall onto the black hole, tremendous amounts of energy are released in the form of radiation across the electromagnetic spectrum.
This newly discovered quasar, cataloged as J0313-1806, beats the previous record-holder by over 100 million years. It was discovered after over 1,000 hours of observations by Webb’s NIRCam instrument. At over 13 billion lightyears away, the quasar’s light has traveled for most of the universe’s lifetime to reach us.
“It’s amazing that we found such a luminous quasar so early,” said astronomer Xiaohui Fan of the University of Arizona. “The universe was still in its infancy when this super massive black hole formed.”

The fact that this black hole formed so early in the universe’s history challenges our current models of black hole formation and growth.
“Based on our current theoretical models, a supermassive black hole shouldn’t have existed this early on,” said Fan. “There simply wasn’t enough time for it to accumulate so much mass.”
This discovery indicates that the first black holes must have formed even earlier under special conditions in the early universe.
Seeds of the First Black Holes
According to the most widely accepted models, the predecessors to supermassive black holes were born from the remnants of the universe’s first stars. As each generation of stars ended their life cycles and exploded as supernovae, they left behind dense stellar remnants. Over time, as more stars formed and died in close proximity, their remnants could merge together into even more massive objects.
“The discovery forces us to consider how black holes could have grown so large, so quickly after the Big Bang.” said Priyamvada Natarajan, a black hole researcher at Yale University.
One leading theory proposes that supermassive stars, over 10,000 times more massive than our Sun, may have provided the initial seeds. Supported by huge gas reservoirs in the early universe, these behemoths could have collapsed directly into black holes up to 100,000 solar masses. From these early seeds embedded within large galaxies, runaway growth could have swiftly led such black holes to balloon in size.
This discovery demonstrates that special mechanisms must have been in play to jumpstart such rapid black hole growth before quasars like J0313-1806 came to existence. Unraveling these mysteries can reveal key insights into the earliest epochs of our universe.
Signs of Another Black Hole Even Earlier in Cosmic History
Incredibly, evidence also indicates there may have been another supermassive black hole even earlier than JWST’s recent discovery. Data from the Chandra X-ray telescope suggests signs of a quasar named PŌniuāʻena that existed about 750 million years after the Big Bang.
“PŌniuāʻena has tantalizing evidence that it could be the previous record holder before J0313-1806,” remarked astronomer Niel Brandt of Penn State University. “But we need additional observations to confirm its nature and distance.”
If verified, PŌniuāʻena would push back the dawn of supermassive black holes even closer to the Big Bang itself. Astronomers eagerly await upcoming observations that may settle whether it snatches the record.
Regardless, these recent discoveries are reshaping our knowledge about the growth of early cosmic structures. Supermassive black hole seeds clearly developed quicker and grew larger at earlier times than current theories predict.
Next Steps: Charting the Rise of Ancient Monsters
Looking forward, the exceptional sensitivity and resolution of the JWST offers an unprecedented opportunity to find even more distant quasars and early supermassive black holes.
“JWST’s instruments cover infrared wavelengths invisible to Hubble, allowing it to detect objects farther away than ever achievable before,” described Emily Levesque of the University of Washington.
In particular, scientists will scour regions around early galaxies from the first billion years after the Big Bang. Within their energetic cores potentially lie the dormant seeds that ultimately progressed into the giant black holes persisting at galaxies’ centers today.
“Discovering and studying quasars within the first billion years will constrain models of black hole formation and growth,” said Levesque. Careful analysis of these primordial monsters containing the most massive black holes can unravel their cosmic origins.
Ultimately charting their proliferation over time will unveil pivotal insights into our universe’s structure, content, and underlying physical laws. From its gravity-defying conception up through the current epoch, supermassive black holes have been influential in shaping the galaxies, stars, and life that developed around them.
The Ancient Glow of a Record-Setting, Ancient Quasar
NASA’s JWST has discovered a blazing quasar, J0313-1806, containing an actively feeding supermassive black hole from when the universe was only 670 million years old. This smashes the prior record of the earliest observed black hole by over 100 million years.
The fact a billion solar mass black hole existed so soon after the Big Bang defies current expectations. This will force astronomers to reconsider models of how the first black hole seeds spawned and bulked up so swiftly early in cosmic history.
JWST’s future surveys of the early universe could uncover even earlier supermassive black holes lurking within the bright cores of ancient galaxies. Understanding the lifecycle of these primordial giants from birth onwards can unlock pivotal clues to the origins of cosmic structures across the universe.
