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
In Exocast-52c Hugh, Andrew, and Hannah take us through three reviews of papers that have been recently published in the planetary/exoplanet literature.
In this episode the Exocast gang are joined by veteran exoplaneteer Dr Mark Marley from NASA Ames. During a nearly hour-long discussion, we probe Mark’s experience of early exoplanet discovery and characterisation efforts in the 1990s, his work on clouds and atmospheric circulation models, ‘ice’ giants, brown dwarfs, his leadership role with the LUVOIR space telescope concept, as well as his cheerleading efforts during the Exocup.
For the second exocast news for 2021 Hannah talks about the physics of raindrops in planetary atmospheres, Hugh explores the color possibilities of the Kepler Photometric data, and Andrew discusses the role of chance in the habitability of the Earth as an exoplanet
The exocast team interview cloud and dust expert Diana Powell (UC:Santa Cruz) about her work on protoplanetary disks and clouds in exoplanet atmospheres. The team also welcome CI Tau b to their adopted planets.
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
The Exocast team tackle the goings on of the #ExoCup2020 twitter competition to crown the exoplanet champion of 2020.
This month Hannah, Hugh, and Andrew go through the slew of exoplanet papers from discoveries, characterisation, and astrobiology
In this episode, the team sits down to ponder the question how many exoplanets are there? At first, this might seem like a relatively straightforward question that can be answered by NASA’s Exoplanet Archive, but it becomes more daunting when considering, for example, the biases and limitations of our instruments that affect our ability to even detect and characterise many planets, how we define a ‘planet’, and whether or not we have surveyed enough stars
On Exocast-45d we bring you the news from across exoplanet research this month with new discoveries, characterisations, habitability and formation papers. In America, WFIRST has been renamed the Nancy Grace Roman Space Telescope in honour to the pioneering “Mother Hubble”, while in Europe the LIFE mission kicked off. We have lots of new exoplanets being discovered (from TESS, NGTS, WASP and RVs), and un-discovered, as was the case for Fomalhaut b. Characterisation studies have also
On this episode we ask the question: Can we ever image the surface of an exoplanet? Once we get all the definitions out of the way, like ‘what do we mean by map?’ and ‘what do we mean by surface?’, we take a deep dive into the realm of instrumentation to discuss the possibilities and limitations of our upcoming and near-future exoplanet imaging technologies. We touch on some of the avenues that astronomers & engineers
In the final of three mini-exocasts we will release this month, we cover some of the notable happenings in exoplanet science over the past month. On this episode we cover new planets from the TESS mission, a novel technique for detecting exoplanets using radio emission, and the end of the very productive KELT survey after 17 years. We also revisit K2-18b, which hit the exoplanet headlines last year after water vapour was definitively detected in
Exocast-43c – On this episode we ask the question: Can we EVER travel to an exoplanet?
Exocast-38b: Exoclimes V voxbox, NASA’s Flagship mission concepts, and exoplanet news including water in the atmosphere of K2-18b
Quizmaster Hugh takes to the conference hall at the 1st TESS Science Conference (TESSCon) to test the attendees’ exoplanet knowledge! Andrew compiles a (not very) top secret report-out on planetary protection. And Hannah covers this month’s news including the detection of an exoplanet magnetic field, new planets from TESS, a Kepler-load of 350 new candidates, as well as advances in exoplanet population statistics and atmospheric characterization. http://media.blubrry.com/exocast/p/www.exocast.org/wp-content/uploads/2019/08/Exocast-37b_v1.mp3Podcast: Play in new window | DownloadSubscribe: RSS

On the 29th episode of Exocast: Hannah is joined by Professor Sarah Hörst from Johns Hopkins University to talk about her lab and working on haze production for solar system planets and beyond. Hugh discusses the concept of Exomoons following the recent potential discovery. Andrew takes a look at the exoplanet news for the past month, and introduces the new format for the Exocup2018!
