Astrophysicist and science communicator Dr Alfredo Carpineti will speak at Humanists UK Convention 2025, taking place from 13–15 June 2025 at the Octagon Centre in Sheffield on ‘Invisible Rainbows’.
The light we can see is only a small part of the whole electromagnetic spectrum. From radio waves to gamma rays, there is so much of the universe that is invisible to us – and we will explore these phenomenal objects and events at Humanists UK Convention in Sheffield.
Tickets for Humanists UK Convention 2025 are on sale now – and running low.
Alfredo is an accomplished astrophysicist and science communicator with a strong commitment to addressing inequity in STEM fields. He has been a staff writer and space correspondent for IFLScience for nine years, where he shares his passion for the cosmos. He is also the chair and founder of Pride in STEM, the UK’s largest charity dedicated to supporting LGBT people in STEM, demonstrating his dedication to fostering inclusivity within the scientific community.
Beyond his work with IFLScience and Pride in STEM, Alfredo is an avid science communicator, producing videos and podcasts under the moniker The Astroholic. His upcoming book, Invisible Rainbows, delves into the astronomical discoveries made possible by observing light beyond the range of human vision – a theme he will explore further at Humanists UK Convention 2025.
Humanists UK Chief Executive Andrew Copson said:
‘Alfredo’s work embodies the spirit of curiosity that all humanists should value. We are excited to welcome him to Humanists UK Convention 2025 and look forward to his illuminating talk on the invisible wonders of the cosmos.’
