Dr Harry Cliff

Dr Harry Cliff is a particle physicist at the University of Cambridge working on the LHCb experiment, a huge particle detector buried 100 metres underground at CERN near Geneva. He is a member of an international team of around 1400 physicists, engineers and computer scientists who are using LHCb to study the basic building blocks of our universe, in search of answers to some of the biggest questions in modern physics.

​Harry spends a lot of time trying to share his love of physics with the public. He has just finished his first popular science book, How To Make An Apple Pie From Scratch, which will be published in August 2021. From 2012 to 2018 he held a joint post between Cambridge and the Science Museum in London, where he curated two major exhibitions: Collider (2013) and The Sun (2018). Harry particularly enjoys talking about science in person and he has given a large number of public talks, including at TED and the Royal Institution, alongside appearances on television, radio and podcasts.

Colin Stuart

Colin Stuart is an astronomy author and speaker who has talked to well over a quarter of a million people about the universe, ranging from schools and the public to conferences and businesses. His books have sold more than 100,000 copies worldwide and he's written over 150 popular science articles for publications including The Guardian, New Scientist, BBC Focus and the European Space Agency.

In 2014 he was awarded runner-up in the European Astronomy Journalism Prize and is also a Fellow of the Royal Astronomical Society. He's talked about the wonders of the universe on Sky News, BBC News and Radio 5Live and been quoted in national newspapers including The Daily Telegraph and The Observer. His TED video on time travel has been viewed over 2 million times.

His other adventures have seen him climb the biggest radio telescope in the UK, stargaze from the Sahara desert and abseil his old school’s science block for charity.

Paul Money

Paul L Money FRAS, FBIS, is an astronomer based in Horncastle, Lincolnshire, England. He is well known for his extensive talks and is the reviews editor of the BBC Sky at Night magazine. He broadcasts occasionally on BBC Radio Lincolnshire and Lincoln City Radio. He was awarded the 'Eric Zucker' award for 2002/2003 for contributions to Astronomy by the Federation of Astronomical Societies. In October 2012 he was also awarded the Sir Arthur Clarke Lifetime Achievement Award for 2012 by the British Rocketry Oral History Project for his active promotion of astronomy and space to the public. From 2004 until 2013 he was one of the three Astronomers on the Omega Holidays Northern Lights Flights and was also a Solar Eclipse Astronomer for their 2006 Turkey Solar Eclipse Trip and their 2009 China Solar Eclipse trip. In 2008 he was the Solar Eclipse expert and part of the expedition team for Poseidon Arctic Voyages on board the Russian Nuclear powered Ice Breaker 'Yamal' for the 2 August 2008 Solar Eclipse, viewed from the Arctic ice near the Franz Joseph Lands Islands. He has published a night sky guide called Nightscenes since 2000 and more recently has become a novelist with a Ghost Mysteries series and several Sci Fi works in the pipeline.

Prof Rene Breton

Rene Breton received his PhD in Physics from McGill University, Canada, in 2009. He is a Professor of Astrophysics at the Jodrell Bank Centre for Astrophysics at The University of Manchester and he currently holds a prestigious European Research Council Starter Grant. His main research interests revolve around the study of pulsars, which he uses to attempt to understand matter under extreme density, gravity and magnetic fields. Some of his past work enabled us to test 'geodetic spin precession' - a phenomenon predicted to exist in General Relativity - for the first time in the strong gravity environment. Rene also has a keen interest for science communication. He co-funded Pulsar Hunters, a citizen science project seeking help from volunteers to find new pulsars.

David Bryant

Following a brief career as a Naval Officer, David Bryant trained to be a teacher at Brentwood College of Education, Essex, teaching across all phases in Norfolk for over thirty years. He gained a science degree from the Open University, and used his scientific knowledge and his passion for astronomy to build up an online business trading in space rocks and other space memorabilia. He has written seven books, many magazine articles and has made numerous TV and radio appearances

Julian Onions

Julian is a post doctoral researcher and astrophysist at Nottingham University. He works with computer simulations of large fractions of the universe to understand trends in galaxy formation and evolution. Investigating the tools that help us form and analyse such simulations such as halo finders, tree builders and semi-analytic models. He also does a number of outreach activities, giving talks to astronomy societies and other interested groups such as rotary and U3A, as well as working with schools and scouts/guide groups. He also helps with the teaching of undergraduates in some of the astronomy courses.
