Exocast-71c: exoplanet news and the 100th episode
In this most excellent 100th episode of Exocast from the team we bring you the latest in exoplanet research and news. Hannah and Andrew cover news from the TRAPPIST system. Hannah will dive into the JWST results that have come out about this very famous system of seven Earth-sized rocky planets. Two papers look to the mid-infrared to measure the light directly from the planets b and c in emission – finding that they likelyRead more

Exocast-71b: Do All Planets Orbit Stars?
In this episode, Hannah, Hugh, and Andrew ask the question: Do all planets orbit stars? Even though the vast majority of planets found so far are bound to a star, there have been detections of planetary-mass objects floating alone through space. Are these planets? How do these objects form, and how can we detect them? Is it possible that these free-floating objects could be considered ‘habitable’? The exocast gang tackle these tricky topics and otherRead more

Exocast-70c: Exoplanet news
Hugh, Hannah, & Andrew discuss a handful of interesting recent exoplanet papers from the past few months. We chat about the news coverage of K2-18b and the claims of biomarkers in that atmosphere, new discoveries, exciting atmospheres, and haze formation. Hannah dives into the controversy of K2-18b and the announcement of DMS (a biomarker on Earth) detection amongst a methane dominated spectrum “Carbon-bearing Molecules in a Possible Hycean Atmosphere” by Madhusudhan et al.. The teamRead more

Exocast-70b: Dr. Max Günther discusses transit detection, chemistry in zero-g & ESA CHEOPS
This month the exocast team chat to exoplanetary astronomer Dr Maximillian Guenther. We talk about finding transiting exoplanets with TESS & NGTS, bright flares from M-dwarf stars, open-source transit modelling, chemical mixing experiments in zero-g aboard the vomit comet, connections between science and art, and his role as project scientist of the ESA CHEOPS mission. And, of course, hear which important and personally connected planetary system he adopted into our hall-of-fame.

Exocast-69b: Surviving Scientific Conferences
In this episode Andrew, Hannah, and Hugh discuss the art and science of organising, and attending, scientific conferences, with a particular focus on the recent Exoclimes VI meeting held in Exeter, UK, organised by Hannah and others in the exoplanet community. These meetings are crucial for the dissemination and communication of new results among the community and further afield, but they can be daunting to attend, and very stressful to organise. The team share theirRead more

Exocast-68c: Latest Exoplanet News
Hugh, Hannah, & Andrew discuss a handful of interesting recent exoplanet papers from the past few months. We chat all things Exoclimes VI held in Exeter in June 2023, new discoveries, exciting atmospheres, and haze formation. Hugh highlights a new discovery of “A temperate Earth-sized planet [LP 791-18 d] with tidal heating transiting an M6 star” by Peterson et al. Hannah dives into an escaping atmosphere covering “Giant Tidal Tails of Helium Escaping the HotRead more

Great topics and insightful commentary. 5 stars ⭐️⭐️⭐️⭐️⭐️
Good science, needs cleaner language
Re-reviewing after listening to more episodes. The scientific information is very solid, but I am not a fan of the occasional profanity. The show is rated as clean, so I expect classier language. I can’t keep listening if they’re going to continue to be unpleasant.
Excellent on Exoplanets!
If exoplanets are your thing, this informative podcast is just for you!
