In this season on life in the universe, it's time to look closer to home: what are the chances we will find evidence of life — present or past-tense — in the Solar System, our own back yard? Emily's fabulous colleague Dr Clément Moissard, plasma phys... more
Having established that the hunt for life in the galaxy ought to begin with an appropriate star, Emily turns our attention towards suitable planets. But what makes a hospitable home for life? It’s complicated, and it seems whatever way we look at it,... more
We're back with Season 3! For the next six episodes we're talking life in the universe, and so far we have N=1: we know there's life on Earth, but nowhere else as yet. Those are challenging statistics. In this episode Emily makes the case that to exp... more
According to one survey, around one-third of Australians think aliens not only exist, but have actually visited Earth. That's ... a bit fraction. In this final episode of season 2, we ask how we'd even find out if life exists around other stars. Emil... more
Exo-planets, sure. Exo-moons and -comets? Fine. But exo ... telescopes?! Emily is going out on a limb in this episode, expanding the definition of telescope to include things that measure stuff in space, and we're here for it! Which means we really d... more
We know, we know — we did exoplanets last time. But that was the current state-of-play and a 2024 exoplanets wrapped update. In this episode, Emily looks to the future! She does a deep dive into the promise of the just wonderful JWST, as it prods exo... more
It couldn't be a season of exo-stuff without taking a good hard look at the current state of exoplanets, the OG exo-thing. Emily sums up the state of exoplanet research in 2024 — her Exoplanets 2024 Wrapped, if you like — then lines up her top three ... more

Great chemistry. not jargon-y
Great content, very knowledgeable, and yet casual and easy to understand.
I enjoy very much your conversations. It’s the perfect pace, very entertaining and engaging. I love how things are exposed. When you talk about sth some questions may come to mind and very often you answer them while explaining. I think you really work on the topics and try to develop them very clearly!! Thanks a lot, please keep doing it!!
Love the topics. Well informed
its realy good and very entertaining, love it, thanks
Love these podcasts - informative and fun! Chris and Emily work well together making the podcasts really engaging
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 ... more
