Research Fellow Dr Mpati Ramatsoku of Rhodes University tells Kechil about mysterious strings around distant galaxies which only powerful radio telescopes can see. In fact, only the local MeerKAT radio telescope has detected them. These connect massive 'lobes' emanating from one particular galaxy. Are there more of these? Does every galaxy have them? What are they? This is brand new research from the brand new MeerKAT telescope in the Northern Cape. Things to be proud about!

Super-massive enormous galaxies - they exist out there with super massive black holes at their centres spewing out great long jets of plasma and who knows what. This is the latest finding from our local MeerKAT telescope, the biggest telescope in the world in the Northern Cape. Dr Jacinta Delhaize is here telling us about them and if that's not enough for you she has a longer podcast on The Cosmic Savannah. You can find the link to it here.

We've heard of gravitational waves, which are being detected by laser interferometers in different parts of the world. But these are detecting high-frequency waves caused by dramatic events such as the collision of supermassive black holes. There is an experiment going on to show that the universe is bathed in a sea of low-frequency gravitational waves.

We start off the year with a mystery. What are ORCs? Odd Radio Circles a million light years across and far, far away. Now with more powerful telescopes coming online like MeerKAT in South Africa and ASKAP in Australia we are finding new things in the cosmos. Here to tell us about ORCs is Ray Norris, a Professor at Western Sydney University.

Here's a round-up of what's going on in space in 2021 - looks set to be a very busy year. For astronomy and scientific discoveries - who knows?

Finally the James Webb Space Telescope has launched into space, on Christmas Day itself, and is now on its way to its destination. Find out about what it's going to do when it gets there, and why this is a very important and exciting space mission.

Just what was the Star of Bethlehem? Was it a star at all? To talk through the possibilities Kechil chats to Christian Hettlage of the South African Astronomical Observatory.

What is a syzygy and why isn't it a good word for Scrabble? There is a 'great conjunction' happening on 21 December. This is the first time such a close conjunction of Saturn and Jupiter has happened since the 13th century.

Simon Ratcliffe has been at the beating heart of the Square Kilometre Array project since the outset - and has in the last 15 years helped to build the biggest telescope in the world. Listen to his highlights and how we beat the Australians with the power of Min. Naledi Pandor, a humble powerpoint presentation, and a great deal of preparation.

The Zone of Avoidance: is this the distance we are supposed to be keeping from each other in these times of Covid? Or is it something to do with that great foreground light polluter, our galaxy? Professor Renée Kraan-Kortweg from UCT tells us what it is.
