Hubble finds new black hole.Reports on the discovery by the National Aeronautics Space Administration (NASA) that deals with a black hole in the Universe which was found by the use of NASA's Hubble Space Telescope. What discovery means to astronomers....
Supermassive black hole. This one has one million billion of times as much matter as a stellar-massive black hole. They are usually found at the centers of galaxies, although astronomers are still unsure about their origin. In the Milky Way, we have this kind of phenomenon calledSagittarius A...
In a binary black hole system, the directions of the spin angular momentum of each black hole (red cone arrows) and of the orbital angular momentum for the system (blue cone arrow) change, or precess, over time. Credit: Midori Kitagawa New research by an astrophysicist at The University o...
When a massive star reaches the end of its lifetime, it can collapse inward on itself to form a black hole. These dense objects then grow by feeding on surrounding gas and dust, but the process can take time. You may like Secrets of Earliest Black Holes Found in Ancient Galaxies A...
The above solution shows that the charged black hole found here contains both electric and magnetic fields. In order to have a real electromagnetic field we need one of the two following conditions(4.15)1.A>0;l<−1or−12−24<l<−12,or−12+24<l<0,2.A<0;−1<l<−12−...
The European Southern Observatory (ESO) announced on May 6 that astronomers have found a black hole that is closer to Earth than any yet discovered. The object is about 1,000 light-years away. It’s close enough that the two stars nearest to it can be seen without a telescope. ...
Currently understood to be intrinsically different depending on their appetites, active black holes are characterized by the layout of their cores and the way they draw in the galactic matter. However, the team found these black holes may have more similarities than previously thought. Their findings...
Importantly, the astronomers found that both Sagittarius A* and the black hole at the center of the galaxy M87 — an object 1,000 times more massive than Sagittarius A* — are similarly built: They both contain the same type of magnetic structures in their swirling disks, even though there...
Now, physicists from MIT and elsewhere have "heard" the ringing of an infant black hole for the first time, and found that the pattern of this ringing does, in fact, predict the black hole's mass and spin—more evidence that Einstein was right all along. ...
The study found that black holes formed from the collapse of massive stars may contribute to dark energy as they grow. By comparing the black hole formation rate with the expansion of the universe, the researchers observed that as more black holes form, the amount of dark energy increases in...
