Black holes

Regular high-energy pulses of gamma-ray radiation emerging from around the Milky Way's central black hole may be coming from a blob of matter whipping around at 30% the speed of light.

Space photo of the week The Gemini South telescope captured the chaotic aftermath of a billion-year-old collision between two spiral galaxies — and their super-close supermassive black holes.

Researchers may have finally figured out how fast-spinning black holes lose energy in the form of enormous energy jets after taking a closer look at the supermassive black hole M87*.

Dubbed the "brightest of all time," or the BOAT, a gamma-ray burst detected in 2022 continues to astound astronomers, revealing severe effects in Earth's atmosphere.

Supermassive black hole Sagittarius A* is spinning nearly as fast as it can, dragging the very fabric of space-time with it and shaping the heart of the Milky Way.

The newly identified quasar, observed 13.7 billion light-years away by the James Webb Space Telescope and Chandra X-ray Observatory, could be an example of a heavy black hole "seed" in the early universe.

Contrary to conventional wisdom, a pair of black holes could exist in perfect pairs without leading to a cataclysmic merger, new research suggests. All it takes is a dose of cosmic expansion.

Astronomers have spotted two huge jets fired off by the 'monster' black hole M87 wobbling on an 11-year cycle, proving for the first time that black holes spin.

A team of astronomers has used a tricky technique to study an ancient galaxy previously lost in the glare of a blazing quasar.

Alexandru Lupsasca and Michael Johnson won the physics prize for their work on photon spheres — weird rings of light around black holes that may reveal a theory of quantum gravity.
