New Model Sheds Light on Spiraling Supermassive Black Holes
A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions…
Black Holes Only Contain Small Percentage of the Universe’s Dark Matter
For one brief shining moment after the 2015 detection of gravitational waves from colliding black holes, astronomers held out hope that the universe’s mysterious dark…
XMM-Newton Observes Matter Falling Into a Black Hole
A UK team of astronomers report the first detection of matter falling into a black hole at 30% of the speed of light, located in…
Looking Back in Time to Watch Massive Black Hole Formation
Black holes form when stars die, allowing the matter in them to collapse into an extremely dense object from which not even light can escape….
Chandra Discovers a Ring of Black Holes in Galaxy AM 0644-741
Astronomers have used NASA’s Chandra X-ray Observatory to discover a ring of black holes or neutron stars in a galaxy 300 million light years from…
Why This Supermassive Black Hole Appears to Move
The study, carried out by two researchers at the Instituto de Astrofísica de Canarias, shows that the “change in position” observed in the nucleus of…
Chandra Reveals Critical Evidence of Elusive Intermediate-Mass Black Holes
Scientists have taken major steps in their hunt to find black holes that are neither very small nor extremely large. Finding these elusive intermediate-mass black…
Further Evidence That Outskirts of Spiral Galaxies Host Massive Black Holes
Findings from a Rochester Institute of Technology study provide further evidence that the outskirts of spiral galaxies host massive black holes. These overlooked regions are…
Astronomers Conduct Successful Test of Einstein Theory Near a Supermassive Black Hole
Astronomers conduct successful test of Einstein’s general theory of relativity near supermassive black hole. The massive black hole at the heart of the Milky Way…
VERITAS Confirms Neutrino Emission from Vicinity of Blazar TXS 0506+056
The VERITAS array has confirmed the detection of gamma rays from the vicinity of a supermassive black hole. While these detections are relatively common for…
Astronomers Trace Source of Cosmic Neutrino to Monster Black Hole
For the first time ever, scientists using NASA’s Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy. This…
Astronomers Investigate Supermassive Black Hole Radio Jet In Unprecedented Detail
In the centre of the galaxy OJ 287, there is one active, super-mass-rich black hole. An international research team led by Silke Britzen of the…
Astronomers Directly Image a Black Hole Ripping Apart a Star
For the first time, astronomers have directly imaged the formation and expansion of a fast-moving jet of material ejected when the powerful gravity of a…
New Evidence of the Existence of an Elusive Type of Black Hole
Scientists have been able to prove the existence of small black holes and those that are super-massive but the existence of an elusive type of…
Gemini Reveals Outflowing Gas from Supermassive Black Hole Nuclei
Supermassive black holes at the nuclei of most galaxies, including our Milky Way, develop gradually as material accretes onto the seed black hole. The physical…
Chandra Views Black Hole Bounty in the Center of the Milky Way
