Black holes

Contrary to conventional wisdom, a pair of black holes could exist in perfect pairs without leading to a cataclysmic merger, new research suggests. All it takes is a dose of cosmic expansion.

Astronomers have spotted two huge jets fired off by the 'monster' black hole M87 wobbling on an 11-year cycle, proving for the first time that black holes spin.

A team of astronomers has used a tricky technique to study an ancient galaxy previously lost in the glare of a blazing quasar.

Alexandru Lupsasca and Michael Johnson won the physics prize for their work on photon spheres — weird rings of light around black holes that may reveal a theory of quantum gravity.

Astronomers found evidence of multiple stellar-mass black holes lurking in the nearby Hyades cluster, just 150 light-years from Earth.

Researchers accidentally stumbled on a way to measure the size of the accretion disks of dust, gas and plasma that surround black holes.

Black holes can swallow matter, and they grow by accreting gas, dust and even the occasional star. But are they the vacuum-mouthed monsters they are often presented to be?

Years after ripping stars to shreds, 24 black holes suddenly flared up with radio waves in inexplicable 'burping' bouts. Half of all star-killing black holes may experience the same.

Almost every galaxy in the universe has a supermassive black hole at its center. So why is it so hard to find young black holes actively feeding?

Einstein's theory of relativity say black holes are 'bald', but a new tweak to his research may give the mysterious objects their long-sought 'hair.'
