The black hole is part of a binary star system within our Milky Way galaxy. It orbits a colossal supergiant companion star.
There are some great opportunities to see the planet travelling across the night skies.
A small add-on to existing gravitational wave detectors could reveal what happens to matter as it becomes a black hole, a process like the big bang in reverse.
Australian astronomers are part of a prize-winning team that was the first to pinpoint the location of a fast radio burst. But there is much we still don't know about these mysterious bursts.
Researchers have found a way to speed up the search for dark matter using technology from quantum computing. By squeezing quantum noise, detectors can now look for axions twice as fast.
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.
Radio galaxies may be the oldest galaxy systems, providing clues to the evolution of galaxies.
Based on what we currently know about the density of giant radio galaxies in the sky, the probability of finding two of them in this region is extremely small.
These results might lead us to revise our understanding of how galaxies stop forming their stars.
Cape astronomers were responsible for, among other things, the first measurement of the distance to a star; the first photographic sky survey and the accurate measurement of the distance to the sun.
A poor start for meteor showers in 2021 but things get better with a possible spectacular surprise later in the year. Here's your guide on when and where to look to catch nature's fireworks.
Visitors are discouraged from the remote desert location where powerful telescopes are listening to the universe.
Cultures around the world call the Pleiades constellation 'seven sisters', even though we can only see six stars today. But things looked quite different 100,000 years ago
From the birth of Jesus Christ to Newton's discovery of gravity, great conjunctions of Jupiter and Saturn have many notable connections in human history.
The 2020 winter solstice is also when Saturn and Jupiter appear closest to each other for 60 years, Here's what you need to know about both the events.
A collaboration between Australian and German scientists gives an unrivalled view of the structure of the Universe.
There's an extensive range of telescopes, mounts and accessories on the market, and trying to pick from it might have you seeing stars. Here's what the experts suggest.
The collapse of the Arecibo Observatory in Puerto Rico was a result of financial neglect – and was a long time coming.
We observed a powerful flare and a huge burst of radio waves from our nearest stellar neighbour, Proxima Centauri, indicating violent space weather around the star.
The Arecibo radio telescope has collapsed but its amazing discoveries will live on.
