Five minutes at the end of each week explores the big and the small questions in astronomy, cosmology, and space science. Hosted by Kechil Kirkham, no subject is too big or too small, and experts are regularly brought on board to illuminate and excite. Cape Town is the place to be for astronomy, with some of the largest telescopes in the world housed or being built not too far away. Looking Up takes advantage of the shoals of scientists and engineers working on the planet’s most advanced ast ...

We are finding out more about planets outside of our solar system. 55 Cancri e is an odd one: it orbits its sun once every 17 Earth hours, and is only 2.3 kms away - can you imagine that? I wonder what it sounds like there. You would definitely not want to visit. It has a molton lava surface and is possibly made out of diamond!…

Kellie Devos is a PhD student at the University of Nottingham, UK, studying the evolution of galaxies in clusters. It sounds rather like living in cities, in that you have a different way of being in different suburbs. She wishes she could visit them in a spaceship, but unfortunately even if you could visit far away galaxies, you might not see as m…

There are many missions to the Moon launching this year, including the Peregrine mission, which was launched recently and has unfortunately already malfunctioned. This show outlines a few of these, some of which are commercial enterprises or collaborations between industry and government space agencies. The Chinese, Japanese, US and private concern…

Have we detected a sign of life on an exoplanet? The chemical signature of DMS has been possibly found by the James Webb Space Telescope. In a year's time we'll have more robust data on this, but it suggests that phytoplankton may exist - that is, life! - on a planet which is not Earth.Af Kechil Kirkham
