Hubble Constant Puzzle Deepens as Supernova and CMB Measurements Clash
Astronomers are testing a new way to measure the universe’s expansion rate using the gravitational-wave background detected by NANOGrav. By treating the cosmic hum from merging supermassive black holes as a statistical “stochastic siren,” researchers hope to calculate the Hubble constant and help resolve the long-standing Hubble tension betwe...

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.

ESA’s Euclid Telescope Charts Over a Million Galaxies in Landmark First Data
ESA’s Euclid space telescope has captured about 1.2 million galaxies in its first year, providing one of the most detailed wide-field surveys of the universe ever made. Covering distances up to 10 billion light-years, Euclid’s clear, expansive imaging is helping astronomers study galaxy shapes, mergers, dwarf galaxy populations, and the role of...

Twisted Jet Confirms Most Extreme Binary Black Hole System in the Universe
Astronomers have confirmed that the blazar OJ 287 hosts the most extreme binary black hole system ever found. Using a global radio telescope array, they captured an ultra-sharp image showing a dramatically bent jet—evidence of two supermassive black holes locked in orbit. The system’s 12-year flare cycle and jet twists match predictions of a sm...

JWST Finds Black Hole Between Galaxy Cores, Hinting at Rare Direct Collapse Birth
Using JWST, astronomers discovered a black hole between two galaxy cores in the Infinity Galaxy—possibly the first direct evidence of a black hole formed by gas collapse, not stellar death. This rare “heavy seed” black hole challenges standard models and could help explain how supermassive black holes appeared so soon after the Big Bang.

When Two Massive Black Holes Merged And Went Flying Across Cosmos
The researchers propose that this ejection resulted from the collision of two galaxies, causing their central black holes to merge into a larger one.

Indian Researchers Spot Rare Triple Black Hole System In Nearby Universe
In a rare occurrence, a merger of three supermassive black holes from as many galaxies in our nearby universe was spotted by a team of Indian researchers, said the Ministry of Science and Technology.
