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 meeting Thursday 29th April 2021 at 7pm

The next meeting of the Astronomy Society will be on Thursday 29th April at 7pm when Fraser Lewis from Cardiff School of Physics and Astronomy will give a talk on the Faulkes telescope. The Faulkes Telescope Project (FTP) provides access to 1,500 hours of observing time on two 2-metre class telescopes located in Hawaii (Faulkes Telescope North in Hawaii) and Australia (Faulkes Telescope South in Australia). This time is dedicated to education and public outreach, mainly in the UK.

The access codes will be sent be separate email.  if you wish to join the meeting but have not received the codes or are not a member of the Society please email me at Observing@AbergavennyAS.org.uk


Brecon Beacons International Dark Sky Reserve, have your say

The Brecon Beacons National Park is presently preparing its management plan for the coming 5 years. There is a consultation process underway that aims to identify the issues that are important to those that live, work or play in the park. The Brecon Beacons is a designated International Dark Sky Reserve. This designation was won and is maintained by the efforts mostly of volunteers who believe that protection of the dark skies should be included in the Park’s 5 year plan; which it currently is not. Protection of the darkness is not just a benefit to stargazers it is crucial for the conservation of wildlife and whole ecosystems. Light can be as important as an environmental pollutant as much as noise, chemicals or other waste materials. If you agree that protection of night time darkness should be included in the plan add your voice to the consultation. Simply send an email before 24th May 2021 to:


and simply say what you value about the dark skies of the Beacons. Please use the phrase “Be The Change “ in the subject line. The more people that respond the more likely it is that the plan will include protection of the night sky. If you want more details on the consultation process you can find the introductory document here:


Next Meeting Thursday 15th April at 7pm

The next meeting of the Society will be on Thursday 15th April at 7pm.  We are very pleased to welcome back Dr Rhodri Evans from the University of Namibia.  Rhodri will present on “Seeing a Black Hole with the Africa Millimetre Telescope“. Rhodri has a 1st class BSc  in Physics from Imperial Colledge and a PhD in Astrophysics from Cardiff University, His thesis was on the amount and extent of dust in normal spiral galaxies. He has worked as a post-doctoral researcher at the University of Chicago and as a Professor of Physics and Astrophysics at Swarthmore College.  He returned to work at Cardiff University and in 2017 moved to Namibia, South-west Africa, to be part of a project to build Africa’s first millimetre-wave telescope.

The meeting will be by Zoom – subscribers will be sent a link by email.  If you are not subscribed but wish to attend the meeting please email me at Observing@AbergavennyAS.org.uk


Next meeting of the Astronomical Society

Owing to some individuals that decided to log into the meeting on the 1st April and disrupt it we had to close the meeting.  It has been decided to re-run the meeting this coming Thursday 8th April at 7pm.  Bob Wright will present the second half of his talk on the Artemis project (this is the third time we have tried to do this presentation – so let us hope third time lucky!).

The link is in the email sent to you but this will not be available on this website – in order to try and deter the unwelcome visitors we had last week.  In addition, when you join the meeting there will be a “waiting room”and attendees will be admitted to the meeting at around 7pm so if you log on a bit early please be patient.  I will also keep an eye out for latecomers during the meeting.  If you want to join the meeting but do not have the link you can contact me at the following email address        Observing@AbergavennyAS.org.uk


Next meeting of the astronomy society is Thursday 1st April 2021 at 7pm

The next meeting of the astronomy society will be on Thursday 1st April 2021 at 7pm.  Bob Wright will present the second half of “The Artemis program”.  This is a U.S. government-funded international human spaceflight program that has the goal of landing “the first woman and the next man” on the Moon.  This talk was originally planned for the 11th March.


Nova in Cassiopeia

A nova has flared up in Cassiopeia.  A nova is caused when a white dwarf in a binary pair has been drawing material from its companion star.  A point is reached where a thermonuclear reaction starts and the white dwarf flares up for a few weeks and is visible right across the galaxy.  It is not to be confused with a supernova which is an altogether less common and more violent affair.  This nova is shining at about magnitude 7.5, that means it is just too dim to see by eye but easily visible in binoculars.  It is also fairly easy to find and the link below gives some clear instructions on how to locate it.  Fortunately it is close to the open cluster Messier 50, and in binoculars it is just below and to the left and in the same field.  These are fairly rare events, astronomers estimate that there are around 50 in the Milky Way each year but only a small proportion are visible from Earth.  There may be some clear nights this week so get your binoculars and go nova hunting!

Next meeting 7pm Thursday 25th February – Observing nebulae

This Thursday Martin Griffiths will give a talk on Observing Nebulae.  Many of you will know Martin from his long association with the Society and the many excellent talks he has given in the past.

There are many forms of nebulae, some easy to spot, others more difficult. In this lecture Martin will explore the best ones to observe and recommend some challenges for the observer and give guidance on instrumentation in order to maximise one’s chances of seeing these wonderful objects.

Topic: Astronomy Society meeting
Time: Feb 25, 2021 07:00 PM London

Feb 2021 – Mars Month?

18th February:  Nasa has managed to crane their rover and helicopter into the Jezero Crater on Mars.  It’s now about 2km from what is thought to be an ancient (that’s 4 billion years ago!) river delta that fed a huge lake.  Jezero is a small town in Bosnia with a population of 1100, Jezero means lake in a number of Slavic languages.  This crater was named in 2007 by the IAU as part of a project to name significant craters after small towns and villages in the world.
Now we await the testing of Perseverance and Ingenuity’s’ systems and for the science data to start to come back.

Mars2020 now joins the two other visitors to Mars this month:-
1)   On the 9th February the successful mission by the UAE to put the Al Amal (Hope) Probe into orbit to study the Martian atmosphere amongst other objectives.  This makes the UAE the 5th country to reach Mars and the second to enter orbit on it’s first try;  and
2)   Followed on the 10th February by the successful insertion of Chinas’ first mission to Mars, Tianwen-1, into orbit.   It also carries a rover that is scheduled to land in May or June.  The Tianwen-1 rover includes a ground penetrating radar that can “see” up to 100m below the surface.
