Our inaugural meeting was on the 8th November 2010 and we officially formed in February 2011.
AAS holds monthly meetings with guest speakers.

All guests are welcome!
No knowledge necessary, just a curious mind.

We are able to provide assistance with setting up your telescope or just helping to find your way around the night sky.

AAS is able to host discussions on subjects as varied as Dark Energy through to 'How dark is your sky'.

Come along and get a new perspective on the universe in which you live!

Meetings – 2018 programme

Welcome to the 2018 programme.  
Our meetings schedule remains the 2nd and 4th Mondays of the month. 
The calendar of dates for the year is set out below, details will be posted on the web-site as the schedule is firmed up through the year.
The normal routine is a discussion group on Cosmology/Basic items on the 2nd Monday and General topics, often with a guest speaker, on the 4th Monday.
 Our venue is in an upstairs room at:

The King’s Head Public House, 59 Cross Street, Abergavenny, NP7 5EU.

It is next door to the Town Hall in the centre of the town.

As usual meetings start at 19:30 and everyone and anyone is welcome to attend, no knowledge is necessary, just a curious mind.

8th January  –  Nick Busby, AAS  :  “Back to Basics”This session is to help you find your way around the night sky, identify constellations and patterns in the stars and remember them.  Finding your way around the sky is a skill that can be learned more easily than you might think – but the learning process can be greatly accelerated when you know a few simple tricks.  Using planetarium software to simulate the night sky and worksheets that you can use afterwards on your own, we will explore the winter sky to understand how to identify, recognise and remember the signposts in the stars.

22nd –  New Year/ Christmas party  :  We join again with friends from Usk Society for an evening of food and fun at the Regency 59.

12th February  –  Nick Busby, AAS  :  The beginners guide to the solar system  :  Using software that models the solar system in 3D, we fly to each of the planets in turn and other objects and find out what they are made of and how it all works.

26th February  –  Kevin Houston, AAS  :  The Invisible Universe  :  Looking at what makes up the Universe.  Topic based on BBC Sky at Night programme, January 2018.

12th March  –  AGM

Agenda for 2018 AGM

AAS AGS-1_2018


26th March  –  Prof. John Davies, Cardiff University, School of Astrophysics and Astronomy  :  Dark Galaxies.  (Prof Davies Current research interests are cosmic dust, low surface brightness galaxies and the history of astronomy in Wales).

9th April  –  Cosmology Discussion Group  :  Subject tbc

23rd April  –  Dr Keith Moseley FRAS, C Phys, M Inst P, MARS (Monmouth Astronomy Research Society) 
The Cassini Mission, launched in 1997, investigated Saturn and its moons between 2003 and 2017. During this period Saturn transited from northern hemisphere winter, through equinox to southern hemisphere winter. This revealed surprising behaviours within Saturn’s atmosphere and magnetic field. Cassini also swung past all of Saturn’s larger moons, dropped a probe on to Titan’s surface and observed changes in Saturn’s rings. Arguably, this was the most successful planetary mission ever.

14th May  –  Prof. Mike Edmunds, Cardiff University, School of Astrophysics and Astronomy  :  Ancient Astronomy: megaliths, landscapes and cosmologies. Prof. Mike Edmunds is always one of our most popular speakers – this is one certainly not to be missed – he is lead academic on the Antikythera Mechanism Research Project, a device made in Greece 2,000 years ago.  In this talk he will discuss how much was known about astronomy in ancient times, before the written word? Did people worry about what happened in the sky? What was their picture of the Universe? This illustrated talk will try to describe what surviving archaeological evidence may and may not be able to tell us. Stonehenge will feature – but there is a lot more besides.

28th May  –    NO MEETING     :     Spring Bank Holiday

11th June  –  Cosmology Discussion Group  :  Subject tbc

25th June  –  Dr Laura Nuttall, Cardiff University, School of Astrophysics and Astronomy  :  Gravitational Waves.  (Dr Nuttall is a member of the LIGO Scientific Collaboration and is co-chair of the data quality sub-group within the LIGO Detector Characterisation Group).
Abstract: The Laser Interferometer Gravitational-wave Observatory (LIGO) consists of two 4-km gravitational-wave detectors in Hanford, WA and Livingston, LA which are operated in unison by the LIGO Scientific Collaboration. These detectors use laser interferometry to measure tiny ripples in space-time caused by passing gravitational waves from cataclysmic cosmic sources. Gravitational waves from the merger of two stellar-mass black holes were observed for the first time in 2015. Since then gravitational waves from similar sources have been detected five more times. In 2017, gravitational waves were observed from a brand new source; the collision of two neutron stars. Along with the gravitational waves the source was also observed across the electromagnetic spectrum, from gamma-rays to radio. These seven observations have truly opened a new era in astronomy. In this talk I will discuss the challenges of detecting gravitational waves, the LIGO detectors and the exciting discoveries we have made so far
