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!

Monday 24th September – Next Meeting

For our next meeting we welcome back Andy Burns, Chairman of the Wiltshire AS and co-director of the Griffin Educational Observatory, Andalucia.
The title of his talk is

Welcome to the Dark Side: 
Dark nebulae, discovery and views

It should be of interest to everyone, with plenty of pictures I am sure.

Andy may or may not mention this particular nebula but above is the famous Horse Head Nebula in the constellation of Orion.  The picture was taken by The European Southern Observatory’s Very Large Telescope in Chile.

Usual time and venue: 7:30pm upstairs in The Kings Head, Abergavenny, next to the town hall.

Monday 10th September – Next meeting

“The trouble with telescopes”

Amateur telescopes come in all sorts of shapes and sizes, have you ever wondered why there are so many different types and what they all do?  In this session we will look into the intrinsic shortcomings of many designs and what has been done to overcome them.  If you are considering buying a telescope of upgrading this will be a useful guide to help you decide.  If you have a telescope and want to get the best out of it this session will give you some top tips.  If you don’t use a telescope but are just interested in how things work, this is the meeting for you!

Monday, September 10th. 19:30, upstairs in the Kings Head, next to the Borough Theatre, everyone welcome.

South West Astronomy Fair

The South west astronomy Fair is held each year at the Norman Lockyer Observatory at Sidmouth in Devon.  This year it is being held on the 11th August.  Sidmouth is about 2.5 hour drive away.  It is a good day out with vintage telescopes on display in the domes, talks and trade stands.  Admission is £8.  More details can be found here.

Even if the weather is inclement there is ample cover to dodge showers.  If anyone is interested in going we can arrange some car sharing, just drop me a line at Observing@AbergavennyAS.org.uk

The weather seems to have broken now the kids are on holiday – typical.  Although it does not get very dark at night there has been some good planetary activity to observe.  The total eclipse of the moon was a damp squib from the UK but Jupiter is still easily visible in the south west at dusk followed by Saturn in the south after midnight.  Saturn’s rings are wonderfully displayed at present so if you have access to a telescope do try and have a look.

Mars is at its closest since the early noughtys and although is very low indeed is very much bigger than normal so worth even looking with the naked eye.  It is the very bright red/orange object low in the south after midnight. It must be said that for those with telescopes the opposition has been a bit of a disappointment.  Dust storms have encircled the planet making it very difficult to see any surface detail.  Hopefully it will settle in the coming weeks.


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.
