Catherine Heymans on the lighter side of the dark universe

Catherine Heymans on the lighter side of the dark universe

Author: BBC Radio 4 July 1, 2025 Duration: 28:34

Have you ever considered the lighter side of dark matter? Comedy has proved an unexpectedly succesful way to engage people with science - as today's guest knows first-hand.

Astrophysicist Catherine Heymans is a Professor at the University of Edinburgh and the current Astronomer Royal for Scotland. She’s spent her career studying dark matter and dark energy: the mysterious ingredients that make up an estimated 95% of our cosmos, but which we still know surprisingly little about. Using increasingly powerful telescopes, both on earth and in space, Catherine has spent years building detailed maps of dark matter - even to the extent of capturing rare images of this mysterious cosmic component.

On top of her research achievements, she's committed to making science accessible to all; not least by taking an astronomy-themed comedy show to the Edinburgh Festival and beyond.

In conversation with Professor Jim Al-Khalili, Catherine talks about her passion for sharing the joys of astrophysics - and reveals how health challenges over the last few years have forced her to readdress her career, her ambitions and even her sense of self...

Presented by Jim Al-Khalili Produced by Lucy Taylor


Hosted by physicist and author Professor Jim Al-Khalili, The Life Scientific offers a rare and intimate glimpse into the minds shaping our world. Each conversation moves beyond the standard lecture or interview, weaving together personal history with groundbreaking ideas. You’ll hear how childhood curiosity, unexpected setbacks, and moments of sheer luck have steered the careers of some of today's most influential researchers. This BBC Radio 4 podcast treats science not as a remote collection of facts, but as a deeply human endeavor driven by passion, perseverance, and sometimes, serendipity. The discussions delve into the real process of discovery-the late-night frustrations, the collaborative breakthroughs, and the ethical questions that arise from new knowledge. While exploring everything from the smallest particles to the vastness of the cosmos, the core of each episode remains the individual behind the science. Listeners come to understand not just what these scientists know, but who they are and what continues to drive them forward. It’s a series that connects the personal to the universal, making complex fields accessible and profoundly relevant. By focusing on the life as much as the science, this podcast reveals how our future is being built, one question at a time, in labs, field stations, and offices around the globe.
