The discovery of the first triple black hole system provides clues to the formation of black holes

A surprising discovery challenges existing models of black hole creation and reveals the age of the stellar system

Light alone cannot create a black hole

Researchers from Canada and Spain have demonstrated for the first time that black holes cannot be formed from the compression of electromagnetic radiation alone. The reason for this lies in a quantum effect that converts energy into particles that scatter from the compressed area and prevent the light from collapsing

NASA's Spitzer reveals the eating habits of Andromeda's supermassive black hole

In images from the decommissioned Spitzer Space Telescope, streams of dust thousands of light-years long flow toward the supermassive black hole at the center of the Andromeda Galaxy. It turns out that these currents can explain how black holes shut down
Scientists have discovered a large black hole that "hiccups", and emits gas fluxes. Analysis revealed that a small black hole repeatedly punctures the gas disk of the large black hole, causing the perturbations to be released. Strong magnetic fields, north and south of the black hole, shown by the orange cone, shoot the flux up and out of the disk. Each time the small black hole punctures the disk, it emits another star, in a regular periodic pattern. Credit: Jose-Luis Olivares, MIT

Black hole "hiccuping" - astronomers are surprised by periodic eruptions in a distant galaxy

In a distant galaxy, the supermassive black hole's intermittent gas fluxes led to the discovery of a smaller black hole in its orbit

Stellar feast: A ferocious black hole "drinks" the equivalent of three Earths from a star every time it passes

A Sun-like star located in a galaxy roughly 500 million light-years away is being gradually devoured by a black hole, shedding a mass equal to three Earths on each close pass.

Webb revealed features of a galaxy 25 billion light years away

The galaxy is currently 25 billion light-years away, but when light began to travel from it to us about 12.5 billion years ago, it was much closer, because the universe is expanding
