Our inaugural meeting was on the 8th Nov 2010 and we officially formed in Feb 2011.
AAS holds monthly meetings, often 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.

We host discussions on subjects as varied as "finding your way around the sky" to "Dark Energy".

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

Next Astronomy Society Meeting Thursday 28th January

The next meeting of Abergavenny Astronomy Society will be on Thursday 28th January.  We will discuss what there is to see in the night sky in the month of February.

Although the Moon is around every month this is the best time to observe it as the ecliptic is at its highest, in other words the Moon has minimal disturbance from bad seeing.  The Moon is a great target for beginners, it’s certainly easy to find but also holds a wealth of interesting features for both the beginner and seasoned observer.  It is also one of the easiest places to cut your teeth in astrophotography.

This is also about the best time for looking for open clusters and we have some showcase ones that are suitable for the naked eye, binoculars or telescope, there is something for everyone.

Finally we will feature the constellation of Gemini with its outstanding twin stars Castor and Pollux.

The meeting will as usual be by Zoom and starts at 7pm, please find the link and credentials below.

The next meeting of the Society will be on the 14th January 2021 at 7pm and by Zoom (as usual these days). 

The talk will be by Nick Busby on the World’s greatest telescopes.  Astronomy has been experiencing a renaissance in the past couple of decades with investment in telescopes and instruments that 50 years ago would have been the stuff of science fiction.  We will review some of the developments that have enabled this technology and have a closer look at the innovations in some of the world’s largest telescopes.

Happy New Year – ctd

Please note the comment added to the previous “Happy New Year” post.

Happy New Year

Wishing you a very happy, peaceful and healthy New Year.

It has certainly been a difficult and challenging year to put it mildly.  Out of necessity we have become used to staying in touch via Zoom but can look forward with hope that at some point this year we will be able to meet again in person. 

On a more positive note and setting aside for a moment the problems that 2000 held, from an astronomical observers viewpoint it was a remarkable year, particularly for those with an interest in our solar system.  Jupiter and Saturn were around for much of the summer although annoyingly low in the sky, but they made up for that with the best conjunction since 1623 on 2000 December 21.  The 1623 conjunction was not visible at night – you would need to go back to 1226 to have seen the next best one and you will not be able to see a similar conjunction until 2080.  The planets also made a spectacular triple with a crescent Moon on the December 16th.

Still on the planets, Mars has had one of its best apparitions in many years.  It was very close and large and thankfully, unlike the last apparition a couple of years ago was not veiled by sandstorms.  It is still observable high in the south west early in the evening although is much smaller and receding rapidly.

In July, literally out of the blue, we had the comet C/2020 F3 (NEOWISE).  This comet was first spotted back in late March during the NEOWISE mission of the Wide-field Infrared Survey Explorer (WISE) space telescope.  Nobody knew then what a beautiful naked eye object it would turn out to be.  It was easily visible at dusk in the northern skies for a couple of weeks.

All of these phenomena could easily be observed by eye and even photographed with basic equipment, which goes to show that you do not need to go to any expense to enjoy the night sky, it can be a very welcome source of joy and diversion from more earthly problems whatever one’s means.


Its been about 10 months since I took up astronomy and being a member of AAS (at least in theory as I didn’t quite make my first meeting before lockdown kicked in early 2020) has helped enormously.
Particularly a big thank you to Nick Busby who has helped me enormously with both setting up my telescope and tips and advice- I have enjoyed the Zoom meetings very much – very informative and interesting thanks to all who gave presentations.
I am looking forward to this new year and observing the night sky, as well as doing a bit of astrophotography – will be great when we can get together for real , have a pint and meet some of you!
Clear skies and thank you!!!

Do it yourself stargazing

Fancy doing it a bit stargazing but unsure how to start or you do not have any equipment?  Don’t worry help is at hand.  A series of podcasts has been produced so that you can listen to a commentary of things to look for by eye or with binoculars at any time of year.  Simply click on the link below, select the podcast you want and away you go.  There is also some advice to help you get the best out of your stargazing endeavours.  And if the weather is cloudy you can just sit and listen from the comfort of your favourite armchair!

Stargazing Podcasts

This project has received funding via the Regional Tourism Engagement Fund and supported through the Welsh Government Rural Communities – Rural Development Programme 2014-2020, which is funded by the European Agricultural Fund for Rural Development and the Welsh Government; the Fund to improve the visitor experience and create stronger destinations by working together.

Many thanks Nick.  A merry Christmas to all!  Mark H

The next meeting of the Society will be  on Thursday 17th December, Nick Busby will present the Mike Thomas  Christmas talk on “Aricebo remembered”.  The radio telescope in Arecibo, Puerto Rico made massive contributions to our astronomical knowledge over the 57 years that it operated.  This talk aims to celebrate its illustrious history by reviewing its history and the discoveries that it made.

Mike Thomas was a very long standing member and friend of Usk Astronomical Society and a talk is dedicated to his memory at the end of each year.

Meeting starts at 7pm, please find the Zoom link for the meeting below:-

There will also be a meeting the following week on Thursday 17th at 7pm, to avoid confusion the link for that meeting will be published later.  The meeting on the 17th will be the Mike Thomas Lecture.  For those not familiar with this event Mike was a founding member of the Usk Astronomical Society and passed away a few years ago.  A talk is arranged each year before Christmas in his memory.  The talk will be remembering another old friend – the Arecibo Observatory which very recently collapsed catastrophically.  This observatory had be operating for 57 years and made many breakthrough discoveries.  This talk, presented by Nick Busby, will look back over its illustrious history.  Unfortunately, this year you will have to supply your own mince pies!

Virtual Meeting Thursday 26th November 2020

The next Society meeting will be on Thursday 26th November.  Bob Wright from Usk Society will present part one of “Worlds among the stars” a talk on exoplanets. 

Around 4200 exoplanets have been discovered to date,  they have been found in all shapes and sizes and have caused astronomers to completely rethink many of the theories of solar system formation.  As the technology develops smaller and planets are being discovered and with the new huge telescopes coming on line in the coming years the prospect of directly imaging some of them will probably become a reality.  Clearly an area of astronomy to watch.

The meeting will start at 7pm, Zoom call details below:

Responses to “Happy Birthday” plus cautionary sky watching tale

Yes a big Happy Birthday to AAS – personally as I joined back in March just as lockdown was coming in, I look forward to attending my first meeting!
Zoom is the next best thing and good fun though
Tony PF

Congrat’s all!!!
Sorry I’ve not joined you in recent meetings. Life is chaotic and working from home / kids, I completely lose all track of time. I’ve even set alarms 5 minutes before, and still missed the meet!
Have spent many nights out with the telescope / binoculars with one of my boys (until the recent inclement weather that is).
Stay safe…

Am having a glass of red to celebrate 10 years…here’s to at least another 10…..cheers….Bri Wigg…

Something to celebrate.  Sorry I’m not more regular. 
This tiny anecdote for Abergavenny AS’s 10th birthday celebrations warns of the dangers of planet watching.
“Having learned via AAS recently of the opportunity for good sightings of three planets soon after dark, I took my binoculars [that someone left in the bunkhouse and never claimed] and walked straight out into the dark. I did not take the precaution of allowing my eyes to adjust and walked straight into the table that had stood on the lawn most of the summer. The tabletop is made of recycled oak staves from an ancient barrel, older, we were told, than our cottage which itself dates from 400 years ago. Very hard and ungiving those timbers are. The blow came right across both thighs but only the left muscle was damaged. It is remarkable how much damage you can do in such a trivial way. Now, over a fortnight later, I am slowly recovering and have stopped taking ibuprofen to relieve the pain. But tennis and cycling are definitely still off the agenda and I must take extreme care when walking down muddy slopes to avoid any risk of slipping. Lesson well learned.
So when you next go planet watching or star gazing- take a torch!”

Happy 10th Birthday

One of our founding members has pointed out to me that yesterday, the 8th November was the 10th birthday of Abergavenny Astronomical Society, it was 10 years since we first met in the Kings Arms in Abergavenny.  It certainly doesn’t feel like 10 years time has passed so quickly!  Looking forward to the time when we can all meet again in person safely.
