Pro Derek Ward-Thompson, UCLAN

UCLan‘s Professor Derek Ward-Thompson is one of the 347 world-leading scientists who formed the Event Horizon Telescope (EHT) collaboration. The scientists will share the 2020 Breakthrough Prize in Fundamental Physics, which is worth three million dollars.  Professor Ward-Thompson said: “This is a great honour for the team to receive this award. It is a truly international collaboration and it was a remarkable achievement. The Breakthrough Trust are to be thanked for their generous acknowledgment.”

 CAS July Meeting


The Great Moon Hoax 
Dr Steve Barrett of Liverpool University

This promises to be an interesting discussion of a leading conspiracy theory! Or should that be a hypothesis? LOL!

Lecture - June 30th 

The Stonyhurst College expedition to the total solar eclipse of 1914  

Mr Graham McLoughlin, Preston AS


The total solar eclipse of 1914 August 21 had the misfortune of taking place at the beginning of World War I. Its central line crossed an area of eastern Europe that had been thrown into conflict only weeks earlier when Germany declared war against Russia on August 1....  This lecture promises to be a fascinating insight into the struggle of scientists to gather information against the background of a world war was erupting.

APRIL MEETING: The next meeting of CAS will be at 1930 hours on Wednesday, 28th April 2021. As usual (nowadays) the meeting will be held on Zoom.

The speaker is Professor Ian Morison, who has served as Emeritus Professor of  Astronomy (Gresham College) and who continues to work at Jodrell Bank.  His talk will be entitled "Astrophotography with a DSLR or mirrorless camera". Professor Morison has wide experience in observational astronomy and he will show that excellent photographic results do not require you to be situated at the top of a mountain in Chile nor plugged into Hubble !

If you would like to attend the meeting please send an e-mail to the society's Chair and he will forward an invitation/link shortly before the meeting. Note that all meetings are for members who have now paid their membership fees.

Clusters of Galaxies - Light in the Dark Spaces

Prof. Chris Collins

Professor of Cosmology within the Astrophysics Research Institute (ARI) of Liverpool John Moores University. 

My research covers topics in observational cosmology focussing on studies of the evolution of galaxies and clusters of galaxies over cosmic time and their large-scale distribution in space. These interests probe theories of how galaxies develop from seed density perturbations in the very early Universe and also provide constraints on cosmological parameters such as the amount of dark matter and dark energy. 

If you would like to attend the meeting, please send me an e-mail the Chair at this address  he will then forward to you the "official invitation" and Zoom link in due course.
