The Looking Glass Universe – From Baryogenesis to Biogenesis

Is there a connection between the excess of matter over antimatter and handedness in biology?

Friday 6th November 2020 at 7.30 pm on Zoom, Dr Bob Fosbury, How the Sun Paints the Sky (video recording and extended paper)

Unless they are astronauts, humans must view the Universe through the window of the Earth’s atmosphere. Although a clear sky is relatively transparent to visible light, bright astronomical objects — most noticeably the Sun — can paint the entire sky with luminosity, colour and shadow to be captured by both landscape painters and photographers. How […]

Friday 2nd October 2020 at 7.30 pm on Zoom, John I. Davies, Joint BIS/HS lecture – First Steps to Interstellar Probes- i4is Project Glowworm

The lecture will explain i4is Project Glowworm – a near term low earth orbit demonstration of laser push technology. This is a first step to interstellar probes using that technology. The lecture will explain the motivation for this project, set out the history of, and physical basis for, laser propulsion, summarise the alternative means of […]

Friday 4th September 2020 at 7.30 pm on Zoom, Dr Dirk Froebrich, The HOYS-CAPS Project – Hunting Outbursting Young Stars

The talk will introduce the Hunting Outbursting Young Stars (HOYS) citizen science project. They work with amateur astronomers to study the formation of stars and planets. We will give a brief overview on how stars and planets are forming and discuss how the project relies almost exclusively on data taken by Amateur Astronomers. The second […]

Our lecture programme has been suspended from April 2020 onwards

Our lecture programme was suspended from the beginning of April 2020 onwards because of the Covid-19 pandemic. Therefore the planned lecture by Michael Perryman on Friday 3rd April 2020 did not take place. The title was “Hipparcos and Gaia – Space Astrometry: unravelling the formation and evolution of our galaxy”. Also cancelled for now is […]
