In this episode the Exocast team talk with Dr Megan (Meg) Schwamb about her work from the solar system to distant exoplanets and citizen science. The show is jam packed with exciting science and enough ice cream analogies to build an Exocast Parlour. We discuss in detail the process of going from a strange looking light curve posted in PlanetHunters Kepler to publication and bonafide planet, how you can track ice formation at Mars’ poles, and take a look to the farthest reaches of our solar system to ask what is out there and what does that mean for our planets formation history. Meg also inducts PH-1b into the Exocast Adopted Planets family.
In this episode the Exocast team take us through three of the latests studies in exoplanet research touching on biosignatures, planet formation and disruption, and the effects of space weather on close-in exoplanets. Join them to learn the latest in exoplanet science!
This month Hugh, Hannah and Andrew discuss a deceptively simple question about the limits of planetary size… Exocast-57b takes you from measurements of exoplanet radius and mass, the difficulty with the IAU definition of planets, to the formation of brown dwarfs and stars. They even dive into the importance of size on habitability, the size limits of a rocky world compared to a gaseous world, some of the stand out candidates for the “biggest” exoplanet,
In this episode the Exocast gang chat with Dr Mark McCaughrean, who is a Senior Advisor for Science & Exploration at the European Space Agency (ESA), as well as a James Webb Space Telescope (JWST) Science Working Group Interdisciplinary Scientist, about the recent launch, deployment and commissioning of JWST. Mark shares scientific and personal highlights of his long involvement with the telescope, his experience of JWST’s launch from French Guiana on Christmas Day 2021, and
That’s right it is that time of year again where the Exocast team pit planet against planet in the Twitter poll show-down: ExoCup! In this episode Andrew, Hugh, and Hannah look at the rundown of exoplanets that were mentioned the most in the past year of research publications and the top 23 join last years ExoCup2020 winner WD-1856b to fill out the first 24 exoplanets in Pots 1, 2, and 3. They then take a
In this episode the Exocast crew are excited to talk with expert science communicator, JAXA space scientist, and master of computer simulations, Professor Elizabeth Tasker. During the hour long discussion we talk about how Elizabeth transitioned into planetary research from a degree and PhD in galactic simulations, the journey from the UK to the US, Canada and now in Japan. Where the idea for her popular science book The Planet Factory came from and why
For the first Exocast News of 2021, Hugh talks about the Direct confirmation of Beta Pic c, Hannah discusses simulating the photochemical haze of hot Jupiter HD189733b, and Andrew takes us through the science and drama surrounding the detection of phosphine in the atmosphere of Venus
In this months episode Exocasters Hugh Osborn, Hannah Wakeford, and Andrew Rushby attempt to answer the question they posed last year: What is the point of the Habitable Zone?

In the 20th episode of Exocast we discuss all things #ExoCup What is the ExoCup? How was it conceived? What was the result? Why was it so stressful for the Exocast crew? We take a voxbox from some members of the exoplanet community on their opinions of the ExoCup (inc. Dr. Jessie Christiansen, Dr. Nikole Lewis, Dr. Natalie Batalha, Dr. Abhi Rajan); Andrew reports on the months interesting exoplanetary news that was still churning out
The Exocast Exoplanet #ExoCup Head-to-head fight to the finish. 32 exoplanets go in one becomes the champion! You can see fun facts about all of our competing exoplanets by checking out the Exocast ExoCup cards. The #ExoCup Cards: The data for the cards was compiled from a number of sources including: NASA Exoplanet Archive, exoplanets.org, Transiting Exoplanet Catalogue (TEPCat), Planetary Habitability Laboratory, and any related journal articles or news stories concerning the individual planets. The

In the 14th episode of Exocast Hannah takes us back to basics and introduce the composition and chemistry of exoplanet atmospheres. Andrew covers some recent updates from astrobiology, the field of study that aims to figure out if there’s life on any the exoplanets we’ve discovered, or on some of the worlds closer to home. Hugh takes us through the latest in exoplanetary news, including the newest discoveries, investigations, and notable events in exoplanets this month.
In the 13th episode of Exocast Hugh talks about planets in binary systems – are two stars better than one? Hannah discussed the importance of brown dwarfs as the intermediary between planets and stars. Andrew takes us through the latest in exoplanetary news, including the newest discoveries, investigations, and notable events in exoplanets this month. and Hannah adopts WASP-12b with it’s ruby clouds into our extreme family of exoplanets. http://media.blubrry.com/exocast/www.exocast.org/wp-content/uploads/2017/04/Exocast-13b_v1.mp3Podcast: Play in new window | DownloadSubscribe:
