Growing Worlds

Do you want to get involved in real exoplanet research? Listen as hosts Jeni and Lorenzo are joined with Anastasia Kokori, a PhD candidate in Exoplanetary Science at University College London. Anastasia is the coordinator of ExoClock and ExoClock Unlocked, an international effort that brings together professional astronomers, students, and amateur observers to monitor exoplanet transits and add to the development of exoplanet research. Anastasia tells her story, from a teacher in primary education to the exoplanet expert she is today and shares her incredible passion for science communication. She is an advocate for communicating science in a way that is accessible to all and ensures growth of the scientific community. Listen to hear more about the exciting work of Anastasia and ExoClock and how you can make significant contributions to exoplanet understanding.

Dr Raissa Estrela from NASA's JPL explains how exoplanet observations reveal clues to Earth’s past and perfect balance. Your hosts, Jeni and Lorenzo, chat with Raissa about exoplanet spectra, through which scientists can decode the fingerprints of distant atmospheres, revealing chemical compositions, evolutionary stages, and even parallels to early Earth. These comparisons act as the perfect ‘textbook’ for understanding how planets form, change, and sustain life. Ultimately, Raissa’s message is clear: by studying other worlds, we learn the value and fragility of our own.

Bring yourself back to Earth through an inspiring chat with Dr Giulia Roccetti, an ESA research fellow at the European Space Astronomy Centre in Madrid. Hosts Jeni and Lorenzo join Giulia for a discussion about the innovative approach of using Earth as a proxy for exoplanet research through the investigation of Earthshine. Giulia’s journey started from her ever-present passion for environmental science, which led her to research that combines atmospheric physics, climate science and exoplanet research. She now develops advanced radiative transfer models to simulate how planets interact with light, using Earth as the test. Listen as Giulia talks us through the ‘pinball’ path of photons between Sun, Earth and Moon, and the complexities of modelling Earth’s atmosphere.
