Exocast-64b: Interview with Dr Naomi Rowe-Gurney

This month Hannah, Andrew, and Hugh are joined in the virtual Exocast studio by planetary scientist Dr Naomi Rowe-Gurney. Naomi is a postdoctoral fellow at NASA’s Goddard Space Flight Center and Howard University in the USA where she works on all things Ice Giants (Uranus and Neptune) in particular looking at them with JWST. The perfectly timed episode follows on from newly released images of Neptune taken with JWST that Naomi had been working on and we discuss the future of Ice Giant science with JWST and a mission to Uranus. After a health giggle session over an excessive use of the word “Uranus” we dive into the science of what a mission to the planet could help us reveal and what makes the Ice Giants so unique.

Exocast-63b: How do planets form?

Hugh, Hannah & Andrew turn their attention to a simple question with a very complicated answer: our favourite! This month we are pondering how planets form. What do we know about planet formation from the Earth, observations from our Solar System, and of distant exoplanetary systems? Where are the gaps in our understanding of the processes involved? Do the theories and models of planet formation hold up to observational scrutiny? We might not be able

Exocast-62c: Exoplanet News

The latest news hot off the Exocast news desk for July/August 2022, another exciting month for exoplanet science: Andrew takes some time to discuss the life and influence of Dr James Lovelock, the co-originator the Gaia Hypothesis, who died recently. His news this month takes the form of two independent but neatly connected papers on the topic of ‘chirality’: ‘The Chiral Puzzle of Life’ by Globus and Blandford, and ‘Directional Aspects of Vegetation Linear and

Exocast-62 b: Interview with Dr. Knicole Colón

This month Hannah, Andrew & Hugh are joined by NASA Goddard’s space telescope expert, Dr. Knicole Colón. Fresh from her NASA TV appearance unveiling JWST’s first exoplanet spectrum to the world, the JWST Deputy Project Scientist for Exoplanet Science gives us a behind-the-scenes look at the big day, as well as how the team got JWST ready for science. She also discusses the ongoing TESS mission searching for new planets, as well as the Pandora

Exocast-60c: Exoplanet News

The latest exoplanet news hot off the Exocast news desk: Hannah gives us a run-down of the Exoplanets IV conference held recently in Las Vegas, at which both her and Hugh were in attendence, including summaries of interesting sessions and presentations. Hugh presents a great new paper from Panahi et al. 2022 entitled “The Detection of Transiting Exoplanets by Gaia” that demonstates the Gaia spacecraft’s ability to contribute to exoplanet detection. Andrew keeps things in

Exocast-60b: Interview with Dr Jennifer Burt

In this episode of Exocast the team are fortunate to be joined in the virtual studio by Dr Jennifer Burt, NASA/JPL’s Extreme Precision Radial Velocity Investigation Scientist, for an extreme discussion of the radial velocity technique for finding and characterising exoplanets. Jenn gives us a comprehensive and enthusiastic rundown of the method, US and European RV surveys, supporting current and future photometric missions with RV follow-up, and an update on new technology and instruments that

Exocast-59c: Exoplanet News

Join us for this months news episode where the Exocast team delve into new discoveries, characterisation, and astrobiology investigations to learn all about the latest research being published in exoplanets. Andrew takes us through some new astrobiology work “Metabolically diverse primordial microbial communities in Earth’s oldest seafloor-hydrothermal jasper“ from Papineau et al. 2022 Hannah covers the latest in characterisation with “A New Analysis of 8 Spitzer Phase Curves and Hot Jupiter Population Trends: Qatar-1b, Qatar-2b,

Exocast-59b: What are planetary atmospheres made of?

This month Hugh, Hannah, and Andrew go back to basics to discuss the diversity and complexity inherent in the study of planetary atmospheres. Exocast-59b touches on how we define an atmosphere and takes a sojourn through the varied and beautiful atmospheres of the Solar System, as well as a journey back through time to consider the long evolution of the atmosphere of our planet. How does an atmosphere form and change over time, cling to

Exocast-58b: Interview with Dr Megan Schwamb

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.

Exocast-57b: How big can an exoplanet be?

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,

Exocast-56b: Interview with Mark McCaughrean about JWST

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

Exocast-55b: ExoCup2021

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

Exocast-53b: Interview with Elizabeth Tasker

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
