James Webb Telescope Discovers Trio of Black Holes in Distant Galaxy
- Astronomers have identified three actively feeding supermassive black holes in the distant galaxy J0148-4214, observed as it appeared approximately 1.2 billion years after the Big Bang.
- This groundbreaking discovery, led by Hannah Übler from the Max Planck Institute for Extraterrestrial Physics, was made possible by the James Webb Space Telescope's spatially resolved spectroscopy.

The James Webb Space Telescope (JWST) has made a significant discovery, observing a galaxy containing three actively accreting supermassive black holes. This is the first time such a trio has been found in a single galaxy in the distant universe. The galaxy, designated J0148-4214, is located over 12.5 billion light-years from Earth, meaning astronomers are seeing it as it existed roughly 1.2 billion years after the Big Bang.
Two of these colossal black holes are situated remarkably close to the galaxy’s center, separated by only about 620 light-years, and are predicted to merge within the next few hundred million years. Their masses are estimated at approximately 80 million and 0.6 million solar masses, respectively. A third black hole, with a mass of about 2 million solar masses, is located further out in the galaxy’s outskirts.
This observation provides crucial insights into how supermassive black holes grew so rapidly in the early universe. The findings suggest that mergers and interactions between galaxies, and consequently their central black holes, played a significant role in their accelerated growth. The JWST’s Near-Infrared Spectrograph (NIRSpec) was instrumental in identifying these active black holes by detecting the distinctive spectral features of matter falling into them. This capability allows astronomers to observe phenomena that were previously undetectable by older telescopes like Hubble. The research, published in the journal Astronomy & Astrophysics, highlights the power of integral field spectroscopy in unraveling the mysteries of the early cosmos.
