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.
Dark matter can be inferred from an assortment of physical clues in the universe.

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.
Elliptical galaxies are filled with extremely old 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.

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
On Dec. 21, Jupiter and Saturn will be so close together they will almost appear to be touching.

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 night will be accompanied by another cosmic event known as ‘the great conjunction,’ when Saturn and Jupiter will appear right next to each other.

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.
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.
