Astronomers have taken a close-up look at the jets of plasma streaking away from a supermassive black hole - one of the strangest and most energetic features of galaxies.
New research can help explain how black holes can produce powerful jets.
Some of the baby radio galaxies found may not be ‘babies’ at all. Rather, they may be ‘angsty teens’, rapidly growing into adults much faster than researchers had anticipated.
If you are a sci-fi junkie you’ve probably wondered what would happen if you were unlucky enough to fall into a black hole. How well you’d fare all depends on the type of black hole.
Roger Penrose helped resurrect Einstein’s general theory of relativity, and Reinhard Genzel and Andrea Ghez showed there was a black hole in the middle of our galaxy.
Like a cosmic butterfly in the sky, radio galaxy PKS 2014-55 was observed by CSIRO researchers with the Australian SKA Pathfinder telescope.
There is a massive black hole in the center of the Milky Way galaxy. Measurements of star orbits near this black hole suggest that there may be a second companion black hole nearby.
New research shows the supermassive black hole at the centre of the Milky Way spat out an enormous beam of radiation 3.5 million years ago
If you got too close to a black hole, it would suck you in and you’d never be able to escape, even if you were travelling at the speed of light.
This point of no return is called the event horizon.
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?
Scientists turned Earth into one giant telescope to capture the uncapturable.
A black hole is an object with such a strong gravitational pull that nothing, not even light, can escape from it.
A number of surrounding galaxies are slowly being devoured by the most luminous object in the sky.
Astronomers have suspected them for ages –now a team as finally spotted a ‘fountain’ in a galaxy far, far away.
Merging supermassive black holes would emit gravitational waves, allowing scientists to detect them.
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.
A giant detector at the South Pole has observed a neutrino from a black hole in a distant galaxy for the first time.
The pull created by a black hole is so strong that if you get too close to one – even if you are travelling away from it at the fastest speed it is possible to go – you will never be able escape.
A team of astronomers captured the moment when a wayward star was pulled into the mouth of a supermassive black hole.
There could be thousands of black holes at the heart of the Milky Way.
