The Search for Advanced Extraterrestrial Civilisations via Anomalies in Astronomical Survey Data

Prof. Michael (Mike) GarrettUniversity of ManchesterJodrell Bank Centre for Astrophysics Image credit: NASA Energy-intensive civilisations are likely to have a significant impact on both their local and extended environments – we already see evidence for this here on Earth. Advanced technical civilisations may reveal themselves to other civilisations by introducing anomalous signals into astronomical data. […]

Hipparcos and Gaia: space astrometry — unravelling the formation and evolution of our Galaxy

Dr Michael Perryman Image credit: ESA–D. Ducros, 2013 The Hipparcos satellite project of the European Space Agency was dedicated to measuring the accurate positions of more than 100,000 stars. Doing so from space represented a fundamentally new discipline in space science. With the publication of the scientific results from the Hipparcos mission in 1997, ESA […]

NASA’s Juno Mission to Jupiter

Dr. Fran BagenalLaboratory for Atmospheric and Space PhysicsUniversity of Colorado, Boulder Image credit: NASA/JPL-Caltech Juno’s principal goal is to understand the origin and evolution of Jupiter. Underneath its dense cloud cover, Jupiter safeguards secrets to the fundamental processes and conditions that governed our solar system during its formation. As our primary example of a giant […]

The Looking Glass Universe – From Baryogenesis to Biogenesis

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

Roger Blandford (KIPAC, Stanford University) Image credit: ESO/APEX & MSX/IPAC/NASA and A.Symes The laws of physics were long thought to be unchanged when viewed in a mirror.We have known for over sixty years that they are not.As Sakharov first explained, this asymmetry, in action during the first moments of the universe, may account for the […]

Wednesday 18th November at 7.00 pm on MS Teams, Caroline Herschel Prize Lecture, Supermassive Black Holes – the Ultimate Galaxy Killers?

Image credit: ESO/WFI (Optical); MPIfR/ESO/APEX/A.Weiss et al. (Submillimetre); NASA/CXC/CfA/R.Kraft et al. (X-ray) The talk is being run by the University of Bath in conjunction with the Herschel Society and the Royal Astronomical Society. There are over one billion galaxies in the Universe, each home to over a billion stars and one central supermassive black hole […]

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 […]
