BBC Radio 4 - BBC Inside Science, Mapping the universe

Catch up on the latest cosmological research that has physicists ‘excited’.

It's been a bumper week for cosmologists. Marnie Chesterton is joined by Andrew Pontzen to get the latest on astronomical findings that have collectively taken decades to record.

A rocket launch, super-massive black holes and ghost particles! This past week’s scientific findings are testament to how hard-at-work cosmologists and physicists have been seeking out the fundamental building blocks of our universe and the rules that govern it. 

Professor of Cosmology at UCL, Andrew Pontzen, joins Marnie Chesterton to discuss the lot of them. Euclid took to the stars on Saturday, carrying a wide-angle space telescope that promises the opportunity to create a far larger and accurate 3D map of the universe to anything ever seen before. Gravitational waves detected by the North American Nanohertz Observatory for Gravitational Waves (NANOgrav) provide insight into the role black holes play in galaxy formation. And neutrinos recorded in the remote ices of Antarctica have been detected from the centre of our Milky Way. 

Dr Stuart Farrimond also joins us for the next few weeks with his pitch on the science of gardening. He’ll be digging up facts and tips that will help make the most out of summer blooms. This week Stu unearths how the pH of your soil could be hindering the flowerbeds.

And visit a Welsh quarry with reporter Ella Hubber to hear how a mere 462 million years ago new species were exploding onto the scene. Palaeontologists Dr Joe Botting and Dr Lucy Muir stumbled across the most abundant and rare deposit of soft bodied fossils on record, scoring an archaeological jackpot!
