Exocast-44c: Can we ever image the surface of an exoplanet?

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

Exocast-42b: Special Guest Dr Stephen Kane

Our final bite-size episode for this month features Andrew, Hannah, and Hugh chatting with Dr Stephen Kane, Associate Professor of Planetary Astrophysics in the Departments of Earth and Planetary Sciences and Physics and Astronomy at the University of California, Riverside. Stephen tells us a little about his need to use all exoplanet detection techniques, his love for our hot and cloudy next-door neighbour Venus, and he tries to sneak two planets into our adopted exoplanet list, before settling on one

Exocast-42c – Water in the Universe

In the second of three mini-casts this month, Hannah, Hugh, and Andrew gather around the virtual table to discuss that weird and wonderful molecule: H2O! The importance of water to our lives is undeniable, but in this show we chat about what makes water so chemically unusual and important in the study of astrophysics, exoplanet astronomy, and astrobiology. http://media.blubrry.com/exocast/p/www.exocast.org/wp-content/uploads/2020/02/exocast_42_feature_water_jan2020-1.mp3Podcast: Play in new window | DownloadSubscribe: Android | RSS

Exocast-40b: Brett Morris talks starspots & astrobiology, the #ExoCup2019 is underway, plus exoplanet news

Hugh chats with his colleague at the University of Bern Dr. Brett Morris about starspots and their effect on exoplanet detection and characterisation, his experience with an astrobiology mission right here on Earth, and he recounts an exciting day in Bern earlier this year. Andrew discusses the labels we apply to the worlds we find, and the gang debates the usefulness of the terms for exoplanet science. And Hannah reads ADS so you don’t have

Exocast-37b: Live at TESScon, an intro to planetary protection, & the month in exoplanet news

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: Android |

Exocast-31b: with special guest Lee Billings, plus Waterworlds and exoplanet news

On the 31th episode of Exocast: Hugh is joined in the virtual exocast studio by Science Journalist Lee Billings a writer for Scientific American and author of “5 billion years of Solitude”. Andrew dives into waterworlds inside and outside of our solar system and what we can learn about habitability. Hannah takes a look at what exoplanet news had been released over the past months and highlights the great work done by furloughed US scientists

Exocast-30b: with special guest Jessie Christiansen, plus ExoCup2018 analysis

On the 30th episode of Exocast: Andrew is joined in the virtual exocast studio by Dr Jessie Christiansen from Caltech/NExSci to talk a little about her work on exoplanet demographics, catalogs, public outreach, and citizen science. Hannah provides an overview of last month’s #exocup, giving us a run down on the stats, the winners, losers, surprises and lessons learned. Hugh takes a look at what other exoplanet news had been released over the past month.

Exocast-29b: with special guest Sarah Hörst, Exomoons, News, and Exocup2018

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! And Sarah adds the not extra-solar, not planet, Titan to the exocast adopted

Exocast-26b with Natasha Batalha, PandExo, RVs, and HAT-P-26b

In the 26th episode of Exocast: Natasha Batalha joins Hannah for a chat about PandExo (the Exoplanet ETC for HST and JWST) and her work on Martian climate modelling. Hugh discusses all things radial velocity: history, current, and future prospects. Andrew covers all of June’s exoplanet news; And Natasha adds “Hannah’s special planet” HAT-P-26b to our gang of Adopted Planets http://media.blubrry.com/exocast/p/www.exocast.org/wp-content/uploads/2018/07/Exocast-26b_v2.mp3Podcast: Play in new window | DownloadSubscribe: Android | RSS

Exocast-25b: Exoplanetary Helium (with guest Jess Spake), plus the “Shadow Biosphere”

In the 25th episode of Exocast: Jessica Spake joins us to chat about the first detection of exoplanetary Helium – around the planet Wasp-107b Andrew covers whether alien biology could exist in a Shadow Biosphere here on Earth. Hannah covers all of May’s exoplanet news; And Jess invites an old friend to the exocast adopted planets – 51 Pegasi b, the first exoplanet detected around a sun-like star. http://media.blubrry.com/exocast/p/www.exocast.org/wp-content/uploads/2018/05/exocast-25b_edit1.mp3Podcast: Play in new window | DownloadSubscribe:

Exocast-18b – Direct Imaging Special with special guest Sasha Hinkley

In the 18th episode of Exocast, we chat to Sasha Hinkley, a direct imaging expert at the University of Exeter: “Spotlights & fireflies” – what it means to be able to directly image planets and how we do it. Why direct imaging may not have the numbers compared to other detection techniques, but can give us so much more information on each planet The future of direct imaging instruments, including JWST, WFIRST and the E-ELT.
