Sometime in 2026, we will discover our 10000th exoplanet, a world around a distant star. This population of worlds has proved remarkably diverse, but hasn’t produced any world like our own. We ask whether this is a coincidence, or whether it could be that our own world is special – and how we might investigate other worlds like our own when we do find them.

This lecture was recorded by Chris Lintott on 4th February 2026 at Conway Hall, London.

Professor Chris Lintott is a Professor of Astrophysics at the University of Oxford, and a Research Fellow at New College.

Having been educated at Magdalene College, Cambridge and University College London, his research now ranges from understanding how galaxies form and evolve, to using machine learning to find the most unusual things in the Universe, to predicting the properties of visiting interstellar asteroids. He was the founder of the Zooniverse citizen science platform, which provides opportunities for more than two million online volunteers to contribute to scientific research, and which was the topic of his first book, 'The Crowd and the Cosmos’. His latest book is ‘Our Accidental Universe’. 

Professor Lintott is best known for presenting the BBC's long-running Sky at Night program, and as an accomplished lecturer. Away from work, he cooks, suffers through being a fan of Torquay United and Somerset cricket, and spends time with a rescued lurcher, Mr Max. He can often be found at the helm of Oxford’s science comedy night, ‘Huh, That’s Funny’.
