Black Hole Spins Like a Top
In 2026, a black hole in the binary system GS 1354-64 woke up: it began pulling matter from its companion star, and a scorching disk swirled around it.
Black Hole Flashes Through the Curtain
The black hole GRS 1915+105 usually hides behind a dense gas curtain: its X-ray emission is heavily absorbed on its way to us. But in April 2023, it suddenly flared: the X-ray flux jumped nearly tenfold.
Dancing Black Holes Put the Universe's Geometry to the Test
The merger of two black holes is like a dance that ends in a powerful burst — a gravitational wave. This wave carries the imprint of how spacetime is curved around the objects. If the geometry differed from what we're used to, as if a ball rolled not on a flat floor but on wavy linoleum, the signal would be different.
Probe will reveal the nature of the nearest black hole
A research probe is planned for the nearest black hole — a region of spacetime whose gravity traps even light. After a hundred years of flight, the spacecraft will enter orbit around the mysterious object to answer a key question: are we looking at a black hole or a neutron star — the ultra-dense remnant of a massive star, compressed to nuclear…
Black hole blinked with a radio flare
A black hole paired with a star works like a pump: it pulls gas from its companion, swirls it into a glowing disk, and occasionally ejects some of that matter in two narrow jets. In 2021, the system 4U 1543-475 put on such a show.
