SUMMARY:Monthly Meeting November - Strange Nature of Time across the Universe - how does time work in Einstein’s cosmos
DESCRIPTION:Strange Nature of Time across the Universe – how does time work in Einstein’s cosmos \nTime. We never seem to have enough of it. Clocks tick reliably\, one second at a time\, as deadlines loom. Yet in our modern understanding of the universe\, time loses its rigidity and reveals a more fluid nature. In this talk\, we’ll explore the nature of time across the cosmos and examine the experiments that show how time once ran slower\, much\, much slower\, when the universe was young. But what does this relative nature of time truly mean? Could it offer a way to gain more time to meet our deadlines? And what does it imply for one of the greatest mysteries in physics: is it possible to break the barrier and actually travel through time? \nGeraint F. Lewis was born in Old South Wales and studied astrophysics at the University of London before earning his PhD from Cambridge in 1995. After research positions in the US and Canada\, he moved to Australia in 2000\, where he is now Professor of Astrophysics at the University of Sydney. His research spans the influence of dark energy and dark matter on cosmic evolution\, the use of gravitational lensing to probe the nature of quasars and the distribution of dark matter\, and the dynamics of galactic cannibalism in the Local Group. Geraint is also a passionate science communicator\, with several books and numerous public talks exploring the deep questions of cosmology\, physics and the meaning of reality.

SUMMARY:Introduction to Astronomy November 2025
DESCRIPTION:The Depth of The Night Sky (An Introduction) \nby guest speaker: Jonathan Park \nWhen we look up at the night sky\, it’s easy to imagine that all the stars are placed on a great celestial dome above us. But we know that they lie at vastly different distances\, scattered across space\, some near and others hundreds of light-years away. In this talk\, we’ll look at some familiar groups of stars\, using graphics to travel away from Earth to view them from different directions. This will help you to get a feel for these distances. While on the topic of how far away these stars are\, here’s an interesting fact: the speed of light is exactly 299\,792\,458 metres per second (no additional decimal places\, no uncertainty)\, and this means we can now define a light-year to 100% precision! You’ll find out how this works tonight. We will also learn a little about some of these stars – are any binary\, triple\, or more? How big and hot are they? Do some of them have planets? One is a fascinating system of at least five stars orbiting each other in a very complex pattern. \nThis talk includes a selection of familiar stars visible to the naked eye\, and is suitable for all ages and levels of astronomy knowledge. It may even change how you think about the stars you see at night.

SUMMARY:Film Night November 2025
DESCRIPTION:The Planets 25 Years Later : Atmosphere\nThe atmosphere of the Earth transforms our planet into our world. The great cycles of the gases of the air and water allow us to understand that home.\nTo understand the planets\, we need to understand their atmospheres. We start with the venture of the late Col. Joe Kittinger\, who travelled to space without needing a rocket\, under an ultra-high atmosphere balloon.\nMikhail Lomonosov discovered the atmosphere of Venus during a rare transit. Soviet exploration of Venus needed to pressure-cook the Venera planetary probes\, making them tougher than battle-tanks\, so as to survive landing\, and take the first photos on its overpowering atmospheric conditions\, and the unending lighting of the ‘Veneran Electric Dragon’\nDave Grinspoon (who writes for Sky & Telescope every once in a while\, and got asteroid 22410 named after him recently) introduces us to the nature of the atmospheres of other planets\, moving through Venus\,\nto Mars. Andy Ingersoll discusses the Ecosphere of a star\, and then turns to the Gas Giants. Dr. Alvin Seiff has in turn designed Galileo’s atmospheric probe of Jupiter’s clouds.\nSaturn is next\, with the coming exploration by Cassini\, and the moon Titan\, the only moon in our Solar System with its own thick atmosphere.\n \nSince 1999\, there have been many developments in understanding the atmospheres of the planets and moons of our Solar Systems\, and the exoplanets beyond:\n\n\nHuygens has landed on Titan\, and the atmospheric conditions are now well described.\nWe know a lot more about the great cycles of Venus’ atmosphere\nWe have been able to confirm the comet-like tails of planets like Venus\, where the atmosphere is being stripped away by solar winds.\nWith the launch of the James Webb Space Telescope\, it is now possible to sample those ‘tails’ by IR Spectroscopy\, and measure their content.\nIn some cases\, we can even detect if those atmospheres contain bio-markers for those present in the Ecosphere of their parent stars.\n\n————–
