Unexplained odd radio circles in the sky are detected by the ASKAP and MeerKAT radio telescopes. The Square Kilometre Array Telescope has been imagined, planned and designed by radio astronomers for over three decades. This effort has led to new technologies and a generation of scientific instruments that are able to detect phenomena in the … Read more
This is the title of a presentation I gave for SciFest, one of the largest science festivals in South Africa. In the era of the pandemic, SciFest has gone on to organise regular talks online, so thank you for the invitation.
Most academics excel at their area of expertise, but not everyone knows how to publicise themselves. I have put together a small website that hopefully will help academics create a simple webpage to showcase their work in all its diversity – research, teaching, supervising, outreach, and more. It also gives links to resources on where … Read more
On the evening of August 24, a bright object traveling fast in the upper atmosphere had thousands of people mesmerised.

On 30 June each year, the African Union celebrates the day of Africa’s Science Renaissance, and it is worth celebrating. African science is among the oldest known to man. The university at Timbuktu, founded around 1 800 years ago, served as an intellectual hub of knowledge for the continent until the late 16th century. There are older records … Read more
