Lovell Lecture Series 2025
19.30 – 21.00
Telescopes around the world are closely monitoring the building-sized asteroid 2024 YR4, working to determine the risk of impact with Earth and highlighting the critical importance of planetary defence efforts. Over the past four years, these efforts have grown as scientists have launched ground-breaking missions to test methods for deflecting dangerous asteroids in the future.
Join Professor Alan Fitzsimmons, a leading expert in planetary defence, to explore how telescopes are used to discover asteroids and calculate impact risks, as well as the cutting-edge solutions being developed to protect our planet.

Alan Fitzsimmons is Professor of Astronomy at Queen’s University Belfast, UK. He is an expert on our Solar System and an author of over 170 scientific papers and reports. Primarily an observational astronomer, he has used telescopes all over the world, from the Very Large Telescope in Chile to the Hubble Space Telescope. One of his specialist areas is planetary defence, working with NASA and ESA to protect us against asteroid impacts. Alan is quite happy that the asteroid and comet named after him will not hit the Earth in the next few thousand years.
