A spinning black hole is pumping vast amounts of energy back into the surrounding universe, but something is causing the jets that transport that energy to wobble very rapidly.
Astronomers say they have "seen what we thought was unseeable" in releasing the first image of a supermassive black hole. So how did we get to this historic observation?
Odd event could be explained by a star being ripped apart by a black hole.
More ripples in space-time have been detected from merging pairs of black holes, one of which was the most massive and distant gravitational-wave source ever observed.
Astronomers traced a single star as it passed close to the black hole at the centre of our galaxy, and detected the telltale signature of Einstein’s gravity in action.
The famous cosmologist was closely identified with black holes due to his revolutionary theoretical work explaining some of their mysterious properties.
Black holes may come in many sizes, but there's still a gap in the middle. The hunt is on to solve the mystery of where are the intermediate size black holes.
A sudden flare and cooling of gas around a black hole has enabled astronomers to measure the magnetic field of a black hole for the first time – finding it much weaker than expected.
Scientists have made a third detection of gravitational waves, again caused by the merger of two black holes. But they think there's something different about the black holes in this case.
The discovery of a new black hole adds to our understanding of these celestial objects that fascinate in both fact and fiction.
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.
The information paradox is one of the great mysteries in our understanding of black holes. But has the famous theoretical physicist Stephen Hawking found the solution?
The best observations yet of a mysterious gas cloud that was heading for the black hole at the hear of our Milky Way reveal it may have more stellar origins.
A supermassive black hole, situated at the heart of our galaxy, erupted in an immensely powerful explosion two million years…
A magnetar - a type of pulsar with a strong magnetic field - has been found at the centre of our Milky Way, allowing researchers…
