Scientists Identify Rare Black Hole Merger in the Early Universe Using Gravitational Mapping
Astronomers have identified two merging supermassive black hole systems named Gondor and Rohan using a new method combining quasars and gravitational wave background signals. The discovery offers a fresh way to map black hole mergers and understand galaxy evolution and cosmic gravitational waves in a clearer and more systematic manner.

NASA’s JWST Uncovers a ‘Feeding Frenzy’ That Births Supermassive Black Holes
Astronomers may have solved how supermassive black holes formed so soon after the Big Bang. New simulations show that gas-rich, turbulent early galaxies allowed brief super-Eddington feeding bursts, enabling ordinary stellar-mass black holes to grow rapidly into the giants seen by JWST.

Indian Team Finds 53 Massive Quasars Blasting Jets Millions of Light-Years Long
Astronomers in India have identified 53 previously unknown giant radio quasars powered by supermassive black holes, each releasing enormous plasma jets reaching up to 7.2 million light-years—nearly 50 times the Milky Way’s diameter. Using GMRT data, the team expanded the catalog of known giant quasars and offered valuable clues about how black ...

Keio University Team Measures Ancient Cosmic Temperature, Confirming Big Bang Prediction
Using ALMA, Keio University scientists measured a 5.13 K cosmic background temperature from 7 billion years ago—matching Big Bang predictions of universal cooling. This precise reading, based on quasar absorption data, is the most accurate at that epoch and offers strong confirmation of how the Universe’s temperature decreases over time.

Astronomers Capture First Image of Two Supermassive Black Holes Orbiting Each Other
Astronomers have captured the first image of two supermassive black holes orbiting in quasar OJ 287. The smaller black hole’s jet spirals due to gravitational forces from the larger one. This discovery validates dual-core theories and opens doors for research on gravitational waves and galaxy evolution.

NASA’s Chandra Finds Black Hole Growing Beyond Known Limits
A black hole in quasar RACS J0320-35, 12.8 billion light-years away, is growing 2.4 times faster than theory permits. Chandra’s discovery challenges ideas of how supermassive black holes formed so soon after the Big Bang.

Supermassive Black Hole Burps Matter at Near-Light Speeds After Consuming Gas Too Fast
Astronomers observed a supermassive black hole expelling gas at nearly a third the speed of light after consuming matter too fast. This outflow could suppress star formation by heating and ejecting gas, revealing how black holes regulate galaxy evolution. The finding helps decode the feedback mechanisms of quasars and active galactic nuclei in shap...

NASA Chandra Spots Distant X-Ray Jet; Telescope Faces Major Budget Cuts
NASA’s Chandra X-ray Observatory has detected a massive X-ray jet from quasar J1610+1811, 11.6 billion light-years away. The jet travels at nearly the speed of light, illuminating black hole behavior during the universe’s early era. However, Chandra now faces potential defunding under NASA’s proposed budget. Astronomers warn that cutting Chan...

NASA’s Chandra Spots Unexpectedly Strong Jet from Distant Black Hole at Cosmic Noon
NASA’s Chandra telescope has spotted two powerful black hole jets from over 11.6 billion light-years away. Detected during the universe’s cosmic noon, these jets reveal rare high-speed behaviour boosted by Big Bang remnants. The findings, which factor in relativistic effects, shed new light on early black hole growth and will be published in Th...

Webb Telescope Uncovers Hidden Active Galactic Nuclei
The cosmic mystery of how quasars and Little Red Dots relate may soon be solved, thanks to new research using the James Webb Space Telescope. A study published on May 7, 2025, in arXiv reveals a population of dust-obscured supermassive black holes in the early universe.
