Scientists Challenge Black Hole Theory, Say Dark Matter Core May Lie At Centre Of Milky Way
Lead author Valentina Crespi explained that this dense dark matter core could bend light so strongly that it creates a dark region in the centre.

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 Spot Ultra-Fast Pulsar Near Milky Way’s Supermassive Black Hole
Scientists have detected a possible ultra-fast pulsar spinning every 8.19 milliseconds near the Milky Way’s central black hole. If confirmed, this rare object could act as a precise cosmic clock, helping researchers study how gravity behaves in extreme environments and offering a powerful new way to test Einstein’s theory of general relativity ...

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.

Astronomers Capture First Detailed View of Hot Gas Swirling Around Black Holes
Japan’s XRISM X-ray observatory has delivered the first detailed maps of hot gas swirling around supermassive black holes in the Virgo and Perseus galaxy clusters. The data reveal intense turbulence, like cosmic storms driven by black hole jets. This churning heats the gas, stopping it from cooling and collapsing into new stars, explaining why cl...

JWST Uncovers the Origins of the Universe’s First Supermassive Black Holes
James Webb Space Telescope observations reveal that the earliest supermassive black holes formed from massive gas clouds collapsing directly into heavy seeds. This process bypassed normal star formation, allowing black holes to reach millions of solar masses within just 200–500 million years after the Big Bang, solving a long-standing cosmic myst...

Astronomers Solve the Mystery Behind M87’s Enormous Space Jet
Astronomers have directly linked the supermassive black hole M87* to its enormous plasma jet using new Event Horizon Telescope data. The findings reveal where the jet originates near the black hole’s shadow, providing crucial insight into how black holes launch matter at nearly the speed of light.

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.

New Dark Matter Simulation Could Change How Galaxies Are Thought to Evolve
Scientists at the Perimeter Institute have developed a new simulation code, KISS-SIDM, to study self-interacting dark matter. The tool shows how rare dark matter interactions can heat and collapse galaxy halos, potentially explaining dense galactic cores and the early formation of supermassive black holes.
