A one-hour brightening in the Large Magellanic Cloud may mark one of the smallest gravitational lenses ever detected, with implications for rogue planets and primordial black holes.

New James Webb Space Telescope analysis suggests the extreme infrared output of W2246−0526, the most distant known Hot DOG, may be explained in part by polar dust rather than the torus alone.

New research proposes an explanation for the unexpectedly massive black holes that the James Webb Space Telescope has found in the universe’s first billion years.

Astronomers used a decade of observations of a distant blazar to show that turbulence in the Milky Way’s interstellar medium adds its own distortions to radio signals from deep space.

An MIT-led team says ultralight dark matter could leave a detectable imprint on gravitational waves when black holes merge inside dense dark matter clouds created by superradiance.

A newly identified X-ray bright object in the young universe could offer astronomers a missing link in the debate over what JWST’s mysterious little red dots really are.

A new analysis of black hole mergers in the LIGO-Virgo-KAGRA catalog points to a separate population of very massive, rapidly spinning black holes formed through hierarchical mergers.

A recent theoretical study argues that evaporating black holes could enter a metastable stage with white-hole-like behavior, extending debates about Hawking radiation, information loss, and the long fate of primordial黑洞.

Using 18 years of radio observations, researchers studying Cygnus X-1 have measured the immense power of its black hole jets and estimated their speed at roughly half the speed of light.

A newly identified ‘X-ray dot’ spotted by Chandra may offer astronomers a crucial link between mysterious little red dots seen by JWST and the growth of supermassive black holes in the early universe.

A new Hubble image of NGC 3137 highlights a spiral galaxy 53 million light-years away that could help astronomers study star formation, black holes, and a galaxy group that may resemble our own.

New research argues that pair-instability supernovae may explain why stellar black holes in a wide mass range appear to be unexpectedly rare.

Astronomers studying three unusual gas clouds near Sagittarius A* say their nearly identical orbits likely share a common origin, with new observations tracing them back to a massive contact binary star system.

A new simulation study helps explain why some stars torn apart by supermassive black holes trigger spectacular flares, offering astronomers a better way to interpret tidal disruption events.

Observations of two dwarf galaxies in the Virgo Cluster suggest past mergers stripped away stars and left behind disproportionately massive black holes, including one that appears displaced from its galactic center.

Astronomers have measured the wobbling jets of Cygnus X-1, the first confirmed black hole, finding that the outflows travel at roughly half the speed of light.

A new Hubble image of IC 486 highlights a barred spiral galaxy 380 million light-years away, where recent star formation and a bright active galactic nucleus coexist in the same luminous structure.

Physicist John Pendry, long known for the invisibility cloak, is now using metamaterial ideas to probe more ambitious territory, including materials that could simulate black-hole-like physics.

A new study of more than 1 million galaxies and over 8,000 actively growing supermassive black holes points to a simple explanation for the modern slowdown in black hole growth: not enough cold gas.

A new analysis of gravitational-wave detections suggests a missing band of black hole masses, supporting the idea that some massive stars explode so completely they leave nothing behind.
