A burst of gamma rays in a distant part of the universe reveals the birth of another black hole.
The first ever picture of the Milky Way's black hole is expected to be a bright crescent shape rather than a disk.
The discovery of a new black hole adds to our understanding of these celestial objects that fascinate in both fact and fiction.
Einstein's theories of relativity underpin our understanding of the universe, yet they're not taught in high school. How can we change that?
The observation of gravitational waves from a second black hole merger implies there are many more black holes in the universe than scientists had previously anticipated.
State of the art detectors have found another signal from a pair of collapsing black holes – the consequences could be momentous.
It was a rare and brief event, but powerful telescopes helped scientists get a glimpse of a black hole letting out a wind at 3,000km per second.
Stargazing seems such a quiet, calm activity. But whether our eyes can see or not, those stars out there are in constant flux. Time-domain astronomy studies how cosmic objects change with time.
The design of a new chip to detect the twisted nature of light waves could pave the way for next generation of optical communication technologies.
A new study suggests that mysterious high energy cosmic rays might originate from the supermassive black hole at the centre of our galaxy.
The hunt to find the source of the gravitational waves detected by LIGO on the sky is only just starting.
The spectacular science of quasars, no hair theorum and spaghettification.
It's taken centuries for our understanding of gravity to evolve to where it is today, culminating in the discovery of gravitational waves, as predicted by Albert Einstein a century ago.
The long awaited discovery of gravitational waves has sent ripples through the scientific world. Here top experts respond to the historic announcement.
The detection of gravitational waves is the final confirmation of Einstein's theory of general relativity, and opens up a new window into the cosmos.
It takes something as stupendous as the merger between two black holes to generate detectable gravitational waves. Here's how such incredible cosmic objects form.
If you understand how a trampoline works, you'll be able to understand what gravitational waves are.
It is the physics discovery of the century – even bigger than the Higgs Boson. Here's how it happened and what it means, by a key member of one of the lead teams
Tanya Hill speaks with Meg Urry about distant galaxies and the supermassive black holes that lurk in their centres.
A new study has failed to find evidence of gravitational waves, but that doesn't mean Einstein was wrong about their existence.
