The discovery opens up the possibility of black hole mergers in globular clusters – a potential source of gravitational waves.
The Cygnus X-1 black hole may be the most massive stellar-mass black hole ever found, at 21 times our sun's mass.
Recoiling black holes, like the one in question, are hypothetical objects that are yet to be definitively spotted.
He said if the Sun became a black hole, it wouldn't suck other planets; the Earth would still revolve around it, except there wouldn't light and the planet would be very cold.
Penrose's Nobel for Physics comes two decades too late, a delayed recognition of important theoretical work
It took the Nobel Committee five decades to recognize the work of Indian-origin astrophysicist Subramanyan Chandrasekhar.
Nobel-winning black hole physics by Penrose, Hawking stands on work of Indian physicist Amal Raychaudhuri
The Raychaudhuri Equation continues to be a key tool in investigating the behaviour of black hole horizons in modern physics.
Nobel Prize 2020 in Physics awarded to Penrose, Genzel and Ghez for findings in cosmology, black holes
Half the award was shared between two researchers that helped discover that every galaxy is home to a supermassive black hole.
A black hole 85 times the sun's mass, and a second, 66 solar masses, collided. The result was a black hole 142 times as massive as the sun.
Black holes are extreme environments and are a testing ground for the laws of physics and our understanding of how the Universe works.
Einstein and Hawking: Master of our Universe makes greatest scientific breakthroughs accessible, exciting
Einstein and Hawking: Master of our Universe, a two-part BBC docu-series, documents their contributions to science.
We saw the first black hole photo, many moon landings, the most distant asteroid ever imaged beyond Pluto among other spectacular wonders.
The groups are located about 380 million light-years from Earth and will form a cluster after the merger.
Researchers are hoping to find signs of large, spinning black holes that can help in the hunt for gravitational waves.
During the star's explosion, it releases the same amount of energy it would release over its entire lifetime.
The observation is 'the best evidence yet' of a trio of supermassive black holes in apparently merging galaxies.
Scientists confirm that black holes are hairless and ring like a bell, gravitationally speaking, when they're born
Scientists have found gravitational wave signals peaking in a sharp curve before fading away, like a bird's 'chirp'.
The flash could be a rare, more extreme case of matter falling into a black hole or neutron star.
So far, massive, star-sized black holes were thought to form only from collapsed stars.
While gravity in a black hole is better understood, the role of its magnetic field on the solar system remains a mystery.
Katie Bouman led the creation of a new algorithm to produce the first-ever image of a black hole.
