Next Talk

Please note that all talks will be held on the Zoom video conferencing platform for the foreseeable future. Invitations to Zoom talks are sent to CAS members shortly in advance. Members planning to watch a talk should try to enter the Society's Zoom "Waiting Room" before 7.30 p.m., as late entry may be distracting for everyone.
The resumption of talks within a lecture theatre environment will be clearly announced.

Thursday 30th September 2021 at 7.30 p.m. "Exo Rings & Exo Moons" presented by Dr Phil Sutton, University of Lincoln

For a number of decades Saturn, its many moons and rings have offered a unique opportunity to study in detail the dynamic relationship between moons and planetary rings. In this talk we recap some of the key aspects of planetary rings and their interactions with nearby moons. The wealth of information taken from observations of Saturn's rings can now be applied to a new and exciting field of planetary rings around exoplanets. Here, we can begin to use exorings as an indirect method of detecting exomoons. While there have been thousands of exoplanets discovered, only handful of exorings and no exomoons have been confirmed. As planetary rings are larger than the planets they orbit, could they offer an opportunity to detect elusive exomoons?

Our speaker:

Dr Phil Sutton is a Senior Lecturer in Astrophysics at the University of Lincoln. I started in 2017 after previously working at Loughborough University as a technical tutor and research technician. I also carried out my PhD at Loughborough which was centre on computer simulations of the interactions of nearby moons on Saturn's rings.

The Society's activities during the coronavirus (COVID-19) pandemic

Home

During the coronavirus crisis the Society wishes to ensure that the risks to CAS members and the wider public are minimised. Accordingly, please note that:

  • for the time being the fortnightly talks in the 2021/22 season will continue to be held using the Zoom video conferencing platform (see the guidance below); and
  • no CAS Star Parties at our Observatory at Dyffryn Gardens are currently planned, and the Observatory is closed until further notice.

We will keep members updated on future developments via this website and other suitable means. We hope everyone stays well during the crisis.

GUIDANCE ON ZOOM: See this short video on how to join a Zoom meeting and this specific CAS guidance

CAS Social on Tuesday Evenings via Zoom (Members Only): Restarting 7pm 14th September

Alternate Tuesday evenings (in the same week as a Society Talk) from 19:00 to around 21:00 we hold a social get together on zoom where we chat about both astronomical and non-astronomical subjects, have a quiz and have presentations by members. These presentations are usually on either member's hobbies or their travels but can be on anything they think others will find interesting.
Why not come along one week to see what you think. You do not need to stay for the whole session and people often arrive late or leave early because of other commitments. It is very informal!
To register your interest email Zoom@cardiff-astronomical-society.co.uk please include your Membership Number and you will be sent a link to the next session.

PART 3: THE CARDIFF ASTRONOMICAL SOCIETY

Introduction to CAS

The Cardiff Astronomical Society (CAS) is a thriving society located in South East Wales. It has been in existence for over 40 years and is one of the largest amateur astronomical societies in the UK. CAS provides a range of facilities for both Society members and the public at large including a varied programme of talks on Thursday evenings (except in August) at the Physics and Astronomy Department of Cardiff University. In addition, regular night sky (and occasional solar) Observing Sessions are held at the Society's own Observatory at Dyffryn Gardens.

Our members come from all walks of life and their knowledge of astronomy ranges from complete beginner to advanced. You don't need any specialist knowledge to join us and neither do you need to own a telescope or binoculars. It's also possible to try us out before joining!

More details about the Society and what it does are available here

We are keen to get more Society members on board to assist with the running of CAS events - please see here how you can Help Us

JOIN OR SUPPORT CAS

Come and join some of the Society's 275 members at one of our talks or observing events. We promise a warm and friendly welcome for all. Only £15.00 per annum also means you can make use of our Library

Gift Aid

CAS is registered for Gift Aid. This means that, if you are a UK taxpayer, we can claim back the standard rate tax on subscriptions (and on any donations) giving an effective 25% boost to the amount the Society has received. However, in order to reclaim these monies from HMRC, we need all members who pay tax to complete and return a Charity Gift Aid Declaration form. Please note that if you have paid your subscriptions by PayPal, you will have already been asked if you would consent to those subscriptions being Gift Aided - but we still need a completed Charity Gift Aid Declaration form in order for us to reclaim the tax paid as Gift Aid.

If you are eligible, please take a form (using the button opposite) and then complete it and pass it to us at one of the fortnightly talks or send it to CAS by post or email (see the bottom of the form). Thank you for your help!

SADLY, THIS ACTIVITY WAS SUSPENDED IN JANUARY 2020 BECAUSE OF A LACK OF RESOURCES WITHIN CAS. IT CAN BE RESUMED ONLY IF MORE VOLUNTEERS COME FORWARD TO PROVIDE HELP

Home

As shown here, Cardiff Astronomical Society welcomes all invitations from organisations such as colleges, schools and guide/scout/brownie groups located in Cardiff and surrounding areas for an outreach stargazing/astronomical event for all ages and levels of knowledge. Society members very much enjoy bringing our passion for the subject to a wider audience and helping everyone to get started in this fascinating subject. We do not charge a fee for our expertise and participation; the enjoyment is enough reward and we will do our very best to ensure a worthwhile and enthralling evening. We would, however, be grateful for reimbursement of travelling expenses and petrol costs to venues outside of Cardiff and its environs. Otherwise the cost would fall on individuals and the non-profit-making Society. It should be noted that CAS has a formal Policy on Child Protection and the Protection of Vulnerable Adults
