SIGMA Stargazing and Equipment Night
SIGMA’s annual Stargazing meeting – a joint club night and public observing session.
Held at Lhanbryde, this event will give members and visitors a chance to see many of the wonders of the local night sky (weather permitting), talk with local amateur astronomers and see SIGMA members’ astronomical equipment.

Maarten de Vries, SIGMA
Most stars, even our own Sun, do not always shine with the same brightness all the time. Some indeed appear to change in brightness quite dramatically over short periods of time. So what causes this? In this talk Maarten will explain the various mechanisms that cause stars to vary in brightness and how observations of some of these stars have helped shape our understanding of the entire universe.

Dr. Oscar Gonzales, Royal Observatory, Edinburgh
How do galaxies form and evolve? Chilean astronomer Oscar Gonzales will show how understanding the formation history of our own galaxy, the Milky Way, is a critical piece of this puzzle. This talk will introduce you to the exciting world of Galactic Archaeology, what clues the astronomers look for, and how they are used to reconstruct the Milky Way’s past.

The Quest for Dark Matter
Dr. Anne-Marie Weijmans, St Andrews University
Anne-Marie will be discussing how astronomers detect dark matter in the Universe. What we think it’s doing there, what we know about it so far and, more importantly, what we don’t know.

Strange Clouds in the Northern Sky
Ken Kennedy – Mill’s Observatory, Dundee
One of SIGMA’s longstanding friends and speaker returns this month to share with us his knowledge of the strange phenomenon of Noctilucent clouds.
Friday 1st June 2018
Annual General Meeting/Solar Observing/ Equipment Night/Social
Another chance to catch up with events within SIGMA over the last year and to elect the new committee.

Confessions of an Astronomer
Prof. Ian Robson, Royal Observatory, Edinburgh
This is a light-hearted and personal look at the life of a professional astronomer. In addition to the research and teaching, perhaps surprisingly, it can be packed with ‘interest’ in the widest sense of the word. The talk contains many amusing and exciting anecdotes; from being marooned with a steaming helium dewar in a cable car in the Pyrenees, flying in an RAF Comet above the North Sea at 45,000ft and many exploits in Hawaii. The talk covers a wide range of astronomy, is lavishly illustrated and contains not a single equation!

From Standing Stones to Blasting Rockets
Matjaz Vidmar, Royal Observatory, Edinburgh
Global Space Industry is in a time of a radical transformation and is no longer the exclusive business of global superpowers or multi-national corporations. Matjaz will link the rich history of astronomy and space science in Scotland to exciting new developments in our ambition to follow these trends and expand our Space Sector. However, building a space industry ecosystem is not trivial – after all, who said it was not rocket science?

Cassini : 20 Years of Discovery
David Paterson, Dundee Astronomical Society
The Cassini – Huygens mission to Saturn was launched in October 1997 took 7 years to reach the ringed planet, carrying out some interesting science on the way. Over the next 13 years Cassini made incredibly detailed observations of this mysterious gas giant, its multitude of moons, and the enigmatic rings, while the Huygens lander gave us our first glimpse of the strange, yet somehow familiar looking, surface of Titan. This talk will look at the engineering challenges of designing the Cassini probe and Huygens lander, the complexity of getting to Saturn, and the wealth of scientific data which has been returned over the 20 year mission.

Please note change of date and talk
Mapping the Universe
Rita Tojeiro, St Andrews University
The structure of the Universe on the largest scales tells us a great deal about its composition, geometry, expansion and ultimate fate.
Rita will review the progress on mapping the large-scale structure of the Universe over the last few decades, show some of the most complete and largest maps that have ever made, and discuss the mysterious cosmological model that these maps have revealed.
Friday 2nd November 2018
Lochaber to the Cosmos
Dr Alec MacKinnon, University of Glasgow
Alec will talk about the Ben Nevis Observatory, the Scots Nobel Prize winner CTR Wilson, and the origins of cosmic ray science with some modern stories on cosmic rays. This promises to be an interesting presentation with a mix of subjects from, high-energy astrophysics, particle physics to Scottish scientific history.
