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!

Next meeting 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!

Meeting starts at 7:30 pm upstairs in the King’s Head – everyone welcome.

Observing session 10th April is cancelled

Unfortunately the weather forecast is not looking good for Tuesday night with  over 90% low cloud until about 11pm when it drops to about 60% cloud cover over Abergavenny.  There is  also chance of light rain.  We will therefore have to look for another date to do some observing, watch this space as they say!

Next Meeting Reminder & Question

Pushed the wrong button and sent out a email by mistake  –  Apologies, K
First the reminder:-
Next meeting tomorrow, 9th April, Kings Head, Abergavenny at 7:30pm.
Topic “Where did all the stuff come from?”.
Elements used to make a smart phone are HERE.   Notes I prepared in December for this topic are HERE

And now a question:
Anyone know where this picture is (it is local) and what it depicts?


Trip to Jodrell Bank and observing opportunity

Jodrell Bank Visit 15th May

In association with Usk Astronomical Society we are arranging a trip to the Jodrell Bank Observatory in Cheshire.  The date is Tuesday the 15th May.  It will be a whole day trip leaving in the morning and arriving bank around 7pm.  The cost of the trip is £7 per person group entry (£5 concessions) and around £8 transport (to be confirmed depending on numbers).  In addition there is the possibility to take afternoon tea (£16.50) and attend a talk by an expert (numbers limited to 28).  If you are interested in attending please let me know asap so that I can make the arrangements.


You can find out more by visisting the Jodrell Bank website:

What’s here?

Observing opportunity

On the 10th April (next Tuesday) we propose to have an informal observing session at the Middle Ninfa campsite just outside Abergavenny, you can see a location map by following the link below:

Middle Ninfa Location

The session will start around 9:30 pm when it is dark.  Beginners very welcome, if you have binoculars bring them along.  You do not need to bring anything but yourself as there will be some telescopes there for you to look through. This will be a very informal session and there is no charge.  We will be watching the weather forecast and will of course postpone the event if the weather is unsuitable (which in truth it has been for what seems like ages!).  Do please check the Abergavenny Astronomical Society website http://abergavennyas.org.uk/

before setting of – we will put a post there indicating if the session is on or off.  If you are subscribed to the site you will of course get the usual e-mail.

On health and safety, observing is usually a very safe pastime, the main dangers being tripping in the dark or dropping weights on toes.  Owing to the informal nature of the event the organisers can accept no responsibility for those attending or their property.  You are therefore asked to be aware of any hazards, and take care; by attending the event you accept these conditions..  It is suggested that you bring a red torch (that does not degrade your night vision) and refrain from using the light in mobile phones, which are very bright.  Also wrap up well!


Next Meeting 9th April

Got one of these? 
Ever wondered where all the stuff that it takes to make one comes from? 
There is a diagram HERE showing the at least  41 elements that go into a common or garden (smart?) mobile phone.

So the question is “How did a universe that started out with just hydrogen end up with all the elements to make a phone or a planet or us?”

Come along the Kings Head, 7:30pm on the 9th April and see if we can figure it out.

Open to everyone – knowledge not required – opinions welcomed
– let’s learn a bit about the universe together –


April Meetings

Advance notice of next month’s meetings:-

Monday 9th April  :  Cosmology Discussion Group  –  subject to be confirmed

Monday 23rd April  :  Keith Mosely, MARS (Monmouth Astronomy Research Society)  :  Cassini or Giant Planets of the Solar System, final topic will be confirmed.

Usual time and venue, 7:30pm at the Kings Head, Abergavenny.  All are welcome.

Next Meeting : Monday 26th February, 2018

The next AAS meeting will be on the topic of January’s “Sky at Night” programme,

The Invisible Universe


The currently accepted model of the universe suggests that normal stuff, that is me, you, the earth, the planets, stars etc, comprises only 5% of the total; the rest is Dark Something or Other.


This BBC programme reviews what we currently know/believe about the composition of the universe and how we are working it out.






The subject will be introduced by Kevin and will consist of 3 short video extracts from the broadcast with time after each video for questions/discussion etc.
The three video extracts are:-
1)         Normal Matter                        :           Baryonic Matter          (5m 32s)
2)         Unknown matter                    :           Dark Matter                (9m 31s)
3)         No idea stuff                            :           Dark Energy                (6m 42s)

If you want to watch the programme it is probably on the BBC iPlayer or you can find in on YouTube at this LINK
Also you can read the “Simple Wikipedia” pages on Normal Matter HERE, Dark Matter HERE and Dark Energy HERE

All are welcome to come along to listen, learn, ask questions, share knowledge or contribute to the general discussion.
Usual time and place : The Kings Head Abergavenny; 7:30pm; Monday 26th Feb.
We look forward to saying Hi on the night.

Next meeting is Monday 12th February, Beginner’s guide to the solar system

The next meeting of the astronomy society is on Monday 12th February.  We will have another “back to basics” session with a beginner’s guide to the solar system.  Using some very cool software, that models the solar system and beyond in beautiful 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.

Below is a screen shot of one of the players in our show – Saturn.


As usual meeting is upstairs in the King’s Head,  it starts at 7:30 pm and open to all with an interest in things astronomical.

Monday 8th January – Back to basics

For all those that got shiny new binoculars for Christmas or even a telescope or for those just starting out in astronomy, 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.  With a bit of practice you will be able to amaze your friends on clear nights by pointing the constellations and even the names of stars!

Usual start time 7:30, upstairs in the King’s Head, everyone welcome.


New Year party

Sick of turkey and mince pies – yearning for something a bit more spicey? Monday 22nd of January is party night. We join again with friends from Usk Society for an evening of food and fun at the Regency 59, 59-60 Cross St, Abergavenny NP7 5EUFurther details on the menu and cost will be posted shortly.  If would would like to attend please let me (Observing@AbergavennyAS.org.uk) or Carol know (secretary@AbergavennyAS.org.uk) as soon as possible so that we can plan numbers.


Next Meeting : Monday 11th December, 2017

This meeting was cancelled due to the weather

At our next meeting we will be having mince pies & mulled wine to mark the season.

The topic will be  :  “Where has everything come from?”
We already know where little boys and little girls come from – slugs & snails : sugar & spice – but where does it all start? 
400 thousand years after the Big Bang all the universe had was hydrogen, helium and a bit of lithium.  So, how were all the other elements made to form the galaxies, stars, planets and, ultimately, us?  That is what we shall be discussing.

I will try, as usual, to share some news items that have caught my interest and to put some briefing notes together prior to the session.  Of course, these stories and notes will be my thoughts and you are free to disagree or correct them!   

All are welcome.  Come along and help us have a stimulating discussion – and eat the mince pies of course.
Usual time and place: 7:30pm in the upper room at the Kings Head.
