Astronomers have measured the spin of a black hole buried in the heart of a galaxy located 56 million light years away, and discovered it was spinning quickly – about as quickly as it could go. That was…
Scientists in the US have successfully used a new NASA telescope to help improve our understanding of how black holes and galaxies evolve. Using data taken by the Nuclear Spectroscopic Telescope Array…
Australian researchers have redefined the relationship between galaxies and their black holes, showing that a widely-accepted method for calculating the mass of smaller black holes was wrong. The breakthrough…
Astronomers have discovered a new, enormous black hole that could change our understanding of how galaxies evolve. Holding the mass of 17 billion suns, the black hole at the centre of the NGC 1277 galaxy…
For the first time, the oscillating signal that heralds the last gasps of a star falling victim to a previously dormant supermassive…
Explosive outbursts of super-hot gas in a galaxy 300 million light-years away have provided evidence of the first known “middleweight” black hole, according to scientists who observed the plasma jets with…
The concept of a “black hole” is one of the most curious in astrophysics. It’s the answer to the question: “What happens if the density of matter in a region becomes so high that not even light can escape…
A population of old black holes, 15 million light years from Earth, has been discovered by astronomers using NASA’s Chandra…
A group of 675 stars has been discovered on the outskirts of our Milky Way galaxy, having been shot out by the black hole…
Last week’s Global Atheist Convention and debates between prominent atheists and theologians in the Australian media has seen arguments about the existence of God getting a thorough airing. In my view…
The Intermediate Mass Black Hole HLX-1 is surrounded by a very young massive cluster of stars, researchers from the University…
Double-star systems called X-ray binaries may give insight into the physics of black holes. X-ray binaries are double-star…
X-ray flares from the supermassive black hole at the centre of the Milky Way may be caused by the regular vaporisation of…
Black holes have long been the staple of science fiction, being monstrous beasts with a gravitational pull that prevents even light from escaping. As well as being useful plot devices, offering mechanisms…
Peruse the astrophysical literature and you could be forgiven for thinking black holes exist. But do they really? What makes a black hole special is its event horizon: a no-return gateway to an unknowable…
What do black holes eat? And do supermassive black holes have fiercer appetites? Let’s remind ourselves of the facts. Lurking at the centre of the Milky Way is a monster, a giant black hole with a mass…
The innermost parts of a black hole’s active jets have been revealed for the first time. The observation, by NASA scientists…
A star that wandered too close to a supermassive black hole has been observed in various stages of decay. The star, which…
Some 3.8 billion years ago a star in the constellation of Draco wandered a little too close to a nearby black hole. The star was violently torn apart by the black hole’s tidal forces, creating two massive…
