Exocast-52b: Why is Venus important for exoplanets?

6/21/2021
In this episode the Exocast team discuss Earth’s twin planet, Venus, and its link to exoplanetary science. We start with an overview of the past, present and future of Venusian exploration, from the first Soviet probes to the three newly-selected missions (DAVINCI+, VERITAS and EnVision) which will explore the atmosphere and surface of Venus more thoroughly than ever before. Then we turn to the open questions about Venus – its potential ancient habitability, the lackRead more

Exocast-51b: Interview with Mark Marley

5/4/2021
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.

In this months discussion Hugh, Hannah, and Andrew discuss the question: Why do we study exoplanets? The team take a look at their own personal motivation and how they each came study exoplanets, as well as diving into the technological applications of astronomy, and the philosophy behind the big questions in astronomy. Astronomy has been at the root of huge technological advances, from the X-ray machines at the airport, to the development of computer languages,Read more

Exocast-46b: Interview with Moiya McTier

7/20/2020
This month Hugh, Andrew, and Hannah talk to astrophysicist, folklorist, and science communicator Moiya McTier. Moiya is an NSF graduate researcher at Columbia University in New York City and works to understand exoplanets from a galactic perspective. The Exocast team talks to Moiya about work from measuring the topography on an exoplanet by the effect that mountains and other features have in transit, all the way up to how the stars in the Milky WayRead more

Exocast-45c: how many exoplanets are there?

6/12/2020
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 starsRead more

5/7/2020
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 & engineersRead more
