Stellar-mass black holes should be in our neighbourhood within about 50 light years of the Solar System. But they're likely isolated, without much to feed on, making them difficul...
Galactic black holes are cosmic mitochondria, powerhouses of the universe. Most of the energy these supermassive black holes produce comes from the material surrounding them: super...
«Роскосмос» продемонстрировал визуализацию объектов, за которыми наблюдал работающий в жёстком рентгеновском диапазоне российский телескоп ART-XC. В космическом агентстве рассказал...
Black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape. When two black holes orbit each other and merge, they produce gravitationa...
According to stellar evolution models, there should be hundreds of millions of black holes floating around in our galaxy. But so far we’ve only found 70. That’s in large part becau...
Black holes are some of the most awe-inspiring and mysterious celestial objects in the universe. This is primarily because astronomers still don’t understand the underlying mechani...
In 1974, Stephen Hawking made a prediction that transformed our understanding of black holes. Black holes, he showed, are not truly black: They slowly lose energy through a quantum...
Scientific estimates show that there should be between about 100 million and 1 billion stellar-mass black holes in the Milky Way. But they aren't easy to locate. They're not like s...
Primordial black holes (PBHs) don't exist as far as we know. But if they did, these hypothetical objects would have formed in the early universe rather than from dying stars, and t...
Astronomers have discovered a star being torn apart by a massive black hole more than 1,000 parsecs from the center of its host galaxy. The tidal disruption event, TDE 2023mfm, was...
Supermassive black holes generate tremendous amounts of energy through their accretion disks and jets. But they can also generate energy through the magnetic Penrose process. A new...
Technion researchers have presented evidence for the existence of solar-storm-like outbursts near supermassive black holes, which can be a million times larger than the sun or more...
Black holes are already some of the strangest objects in the universe, but scientists now say they could unlock an even more bizarre part of the cosmos.
For almost sixty years, general relativity has predicted that black holes are defined by only mass and spin. A new study works out how to check whether some black holes are hiding...
A Supermassive Black Hole May Be Escaping Its Galaxy at 1,000 Kilometers per Second Astronomers have identified compelling evidence that a supermassive black hole is racing away fr...
After analyzing infrared images captured by the James Webb Space Telescope (JWST), an international team of researchers has discovered multiple massive black holes from approximate...
Supermassive black holes power tremendous jets that extend far beyond their galaxy. A new study finds how they can also warm material at the outer edge of a galaxy and reduce the r...
Recently observed objects could be black holes that grew extremely quickly during an early stage of their lives The post Astronomers propose solution for ‘little red dot’ mystery a...
Здравствуйте! Строгая академическая физика и уравнения ОТО Эйнштейна блестяще описывают покадровую динамику уже готового релятивистского "кино" Вселенной. Но ни одно сугубо барионн...
According to new research, "wandering" black holes may have left an imprint on the Universe as they traveled for billions of years.
Nearly every galaxy has a supermassive black hole. The few that don't have had theirs ejected during a galactic collision. That's because galaxies and their black holes have formed...
