Join astronomer Emily and enthusiastic not-astronomer Chris as they explore the universe.
72: Nobel Black Holes
October is Nobel Prize month, and this year the Physics Nobel was shared by three amazing physicists: one who took Einstein's General Theory of Relativity and wrapped some bonkers Escherian mathematics around it to show that these black hole things are real solutions of the equations; and two who then said, OK, let's go find one in the centre of the Milky Way Galaxy. Here's to Reinhard Genzel, Andrea Ghez and Roger Penrose, the newest Physics Nobel Laureates!
71: Penguins on Venus?
OMG life on Venus!!! Well, now, hold on there Tex. Yes, astronomers announced this month that they'd found phosphine in the atmosphere of our planetary neighbour. And yes, phosphine is a pretty decent biosignature, a chemical that is pretty strongly associated with life here on Earth. Emily digs deep to explain the big gap between "Hey, look — phosphine! Huh." and "We found aliens!"
70: Syzygy Summer Spectacular
OK, maybe not *spectacular* as such — but a laid-back summery edition anyway. Emily and Chris share their fave summertime astro-related reads, films, TV shows and podcasts, as well as their go-to sites and apps for fun and retail therapy. Plus, Emily discloses her weird YouTube habits, and shows off her quilting skills. Come for the fun, stay for the puns!
69: Solar Secrets & Nebulous Neutrinos
Fusion reactions in stars, including our Sun, produce huge amounts of neutrinos. These tiny elementary particles are almost impossibly hard to spot: ludicrous numbers of neutrinos are passing through you right now, without noticing your atoms at all. But they're one of the only ways we have to understand the inner workings of the Sun's core — and deep underground beneath an Italian mountain, astronomers have *finally* spotted neutrinos originating from the final piece of the stellar fusion puzzle, the CNO cycle.
68: Birth Of A Planet
The planets we see around us in the galaxy haven't just been hanging around forever, you know. We're pretty sure they must have formed at some point in the past, and more are forming right now, presumably. But it's a rare treat to actually see a planet's birth in progress, which is what astronomers have managed to do recently — in staggering detail!
67: The Mystery of Dark Matter
Live! from the York Festival of Ideas online programme, a zoomtastic chat about dark matter — the strange, unknown stuff that comprises only, what, 80% or more of the matter in the universe. What is it? Why is it? How is it? Emily gives the lowdown on one of astronomy's more embarrassing problems, before we welcome guests Mikhail Bashkanov and Dan Watts, physicists at the University of York who have found something veeeery interesting. It's an exotic particle — a hexaquark, to be exact — that just might solve this cosmic mystery.

Excellent, understandable science podcast.
After hearing a talk by Dr Emily Brunsden and the mention of this podcast series I've now listened to all the episodes to date (latest Episode 08) and I have to say that the alignment of Chris Stewart with Emily is what makes this wonderful. Chris teases out a simple explanation from Emily that is understandable to non-scientists like me, but manages to keep immense detail in to explain in depth the subject of the podcast. A great gift, that I hope keeps on giving.
Five stars from me. Thank you to you both.
Love these podcasts - informative and fun! Chris and Emily work well together making the podcasts really engaging
Best half an hour of the week.
Simple, informative and a pleasure to listen to. What more can you want.
