Many of us have heard of seismology, the study of earthquakes; but what about asteroseismology, focusing on vibrations in stars? Conny Aerts is a Professor of Astrophysics at the University of Leuven in Belgium - and a champion of this information-rich field of celestial research. Her work has broken new ground in helping to improve our understanding of stars and their structures. It hasn’t been an easy path: Conny describes herself as always being “something of an outlier” and she had to fight to follow her dream of working in astronomy. But that determination has paid off - today, Conny is involved in numerous interstellar studies collecting data from thousands of stars, and taking asteroseismology to a whole new level. In an epsiode recorded at the 2024 Cheltenham Science Festival, Professor Jim Al-Khalili talks to the pioneering Belgian astrophysicist about her lifelong passion for stars, supporting the next generation of scientists, and her determination to tread her own path.
