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.

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.
When astronomers started using the new ASKAP radio telescope, they discovered mysterious circular blobs of unknown size and distance in the sky.
Researchers have spotted millions of galaxies in the most detailed radio survey of the southern sky ever conducted. It has smashed previous records for survey speed.
The Earth spins around its axis every day – but gravity keeps us firmly in place.
SpaceX’s satellites will populate the night sky, affecting how we observe the stars. And this is just the beginning of private satellite mega-constellations.
