In August 2026, the James Webb Space Telescope delivered two landmark discoveries that fundamentally change how astronomers understand supermassive black hole growth in the early universe. One team found the closest confirmed pair of actively feeding supermassive black holes ever seen when the universe was young. The other found something even more unexpected: three actively feeding supermassive black holes packed into a single galaxy.
System LID-1166: The Closest-Early-Universe Black Hole Pair
Designation: LID-1166, a dual active galactic nucleus (dual AGN) .
Separation: Approximately 4,900 light-years (1.5 kiloparsecs), making it the closest-separation pair of actively feeding supermassive black holes ever confirmed in the early universe .

What is the short answer to "JWST Finds the Closest-Known Pair of Feeding Supermassive Black Holes — and a Shocking Trio in the Early Universe"?
JWST confirmed LID 1166, the closest pair of actively feeding supermassive black holes in the early universe, separated by just 4,900 light years and seen 1.3 billion years after the Big Bang.
Cosmic epoch: Seen when the universe was roughly 1.3 billion years old (redshift z ≈ 4.5) .
Host galaxy: The system resides in a gas-rich merging galaxy undergoing a major merger. It was originally identified via X-ray selection from the Chandra COSMOS Legacy Survey before JWST zoomed in .
Key instruments: JWST's NIRSpec (Near-Infrared Spectrograph) confirmed the dual nature by detecting broad emission lines characteristic of actively accreting black holes in both nuclei . The Atacama Large Millimeter/submillimeter Array (ALMA) provided high-resolution imaging of the cold gas and dust fueling the rapid growth of both black holes . Together, the JWST + ALMA dataset allowed the team to measure the black hole separation and the physical conditions of the merger .
Key finding: LID-1166 is the first confirmed close-separation (~kiloparsec-scale) dual AGN discovered beyond the local universe. It offers a direct view of the late-stage merger phase when two supermassive black holes are approaching one another before eventually coalescing . The study was accepted for publication in Nature Astronomy.
System J0148-4214: A Shocking Trio of Black Holes
Published in Astronomy & Astrophysics on August 12, 2026, a team led by the Max Planck Institute for Extraterrestrial Physics used JWST to find something even rarer: three actively feeding supermassive black holes in a single galaxy .
Galaxy designation: J0148-4214 .
Cosmic epoch: Seen approximately 1.2 billion years after the Big Bang .
Configuration: Two of the black holes sit remarkably close together near the galaxy's center (just 620 light-years apart), apparently close to merging, while a third black hole lies about 5,500 light-years from the center . The three black holes range from roughly 600,000 to 80 million times the mass of the Sun .
Significance: This is the first evidence of a young galaxy hosting a trio of active supermassive black holes. Two of the three are so close together that they appear nearly indistinguishable without spectroscopic follow-up . The discovery suggests that mergers and interactions in the early universe may have played an important role in the rapid growth of supermassive black holes .

What These Findings Mean
Both discoveries, announced in the same news cycle (August 12–14, 2026), underscore how JWST is revealing complex multi-black-hole systems that were largely invisible to earlier telescopes. The dual system (LID-1166) answers the question of how close two feeding supermassive black holes can get during a merger in the early universe, while the triple system (J0148-4214) pushes further by showing that galaxies could accumulate three actively accreting black holes simultaneously — a scenario that challenges current models of black hole seeding and galaxy assembly .
