A galaxy some 750 million light-years away has been discovered hosting the heftiest pair of supermassive black holes we've ever seen.
Every 76 minutes, like clockwork, the gamma-ray flux of Sagittarius A*, the supermassive black hole in our galaxy, fluctuates, suggesting an orbital motion of something whirling madly around the black hole.
Two NASA space telescopes teamed up to scrutinize a distant galaxy and discovered something mind-boggling: a gargantuan black hole inside a galaxy that’s more than 13 billion years old.
According to a new analysis of a type of galaxy known as a blazar, the best explanation for unusual changes in their glow is a pair of supermassive black holes locked in a decaying orbit.
Scientists have detected an active supermassive black estimated to have been created 570 million years after the Big Bang.
From the far reaches of the observable Universe, astronomers have just seen a supermassive black hole suddenly flare to life.
A survey of the galaxy has revealed hundreds of mysterious cosmic threads pointing towards the supermassive black hole at the heart of the Milky Way. The filaments stretch five to ten light years through space.
A UK team of astronomers found an ultramassive black hole, an object over 30 billion times the mass of our Sun, in the foreground galaxy – a scale rarely seen by astronomers.
Observations of supermassive black holes at the centres of galaxies point to a likely source of dark energy - the "missing" 70% of the Universe.
Australian astronomers have discovered one of the biggest black hole jets in the sky. Spanning more than a million light years from end to end, the jet shoots away from a black hole with enormous energy, and at almost the speed of light.
Scientists have proved that the source of high-energy neutrinos is a special kind of supermassive black holes called blazars.
Located in the bright constellation of Centaurus, this luminous cosmic beast is more than 500 times larger than the supermassive black hole at the centre of our own galaxy.
The international team find that rather than the conventional formation scenarios involving 'normal' matter, supermassive black holes could instead form directly from dark matter in high density regions in the centres of galaxies.
Recently The Low Frequency Array released the first data on its sky survey. They have only mapped 4% of the northern sky so far, but have already mapped 25,000 supermassive black holes.
It is thought that the upper mass limit for galactic black holes is around 100 billion solar masses, but new research suggests the mass limit could be much higher - more than a million times greater than the largest galactic black holes.
