Due to Unforeseen Circumstances, there is a change of speaker and topic for Thursdays talk

Dr Allan Chapman's talk, Mary Fairfax Somerville
has been replaced by

Professor Mike Disney, Cardiff University and CAS
Talk is entitled: Thinking About Galaxies

On September 15th, 2017 members of Cardiff Astronomical Society welcomed Professor Jim Al-Khalili OBE who in 2016 received the inaugural Stephen Hawking Medal for science communication. The thought-provoking talk was entitled "The Search for Extra-terrestrial Life" and gave the audience a review of the past work carried out into this topic, an update on current research and acknowledged the debt to Cassini whose mission had been completed that day.

See below Cassini video.

Would you like to get involved with other activities of CAS?

The committee would like to hear from anyone who would like to give some time to help the committee with some of the activities we get involved with. We are regularly asked to help at public and outreach events on top of those we instigate ourselves and these requests are increasing. We are keen to take part in them as we like to spread an interest in astronomy and this is where we often get new members. These events can be large e.g. Stargazing Live at Dyffryn or small e.g. helping a cub group get their space badge or our own regular observing sessions.

We already have a small group of non-committee members who help on a regular basis and we would be lost without them. We are not asking for a great deal of your time and it doesn't matter if you can only help with one event. And if you don't think you have enough experience to help just yet, why not come along to observe what we do.Being a beginner at astronomy can be a help - it demonstrates to the public that you don't have to have a degree in astrophysics to enjoy the subject and CAS.

Here are some of things you could help with

* Be trained to use main telescope at Dyffryn so that you can help run observing sessions (there are always at least 2 people running these so you would never be on your own). You can also help especially at Star Parties even if you can't use the telescope.
* Come to a public or outreach events to help set up, demonstrate using a telescope, talking to public about astronomy or just pointing people in right direction. Being friendly and approachable is a great asset as these events.
* Give a talk at an event. These will be at novice level sometimes to child groups like beavers or brownies
* Help the publications officer put together the quarterly newsletter
* Take minutes at committee meetings

If you are interested in helping or want to find out more please speak to one of committee or email me at Membership.Secretary@cardiff-astronomical-society.co.uk I will then contact you to find out what help you would like to give and if you are interested you will be put on an email list of people we will contact when help is needed. We do understand that people have busy lives and if you are not available when we ask that's no problem.

Cardiff Astronomical Society

Cardiff Astronomical Society (CAS) was founded in July 1975 by Dr. Bob Owens and Dave Powell at an 'out of London' meeting of the British Astronomical Association held at Dyffryn Gardens. The Society continues to develop its activities, recently applying and acquiring CIO (Charitable Incorporated Organisation) status. The Society is managed and guided by a Committee and a Board of Trustees. Membership has grown over the years and now stands at more than 350, making CAS one of the largest amateur astronomical societies in the UK.

A series of talks is held on alternate Thursday evenings from September to July at Cardiff University Physics and Astronomy Department, members attending meetings usually number over 60 and on several occasions during the year over 100. The programme is varied and comprises of lectures, short talks and debates. The aim is to cater for all interests, at whatever level, beginner or advanced. The Society is able to attract the very best speakers from all over the UK and beyond.

In addition, we hold regular observing sessions at our own observatory at Dyffryn Gardens. Members are able to look up at the sky with the help of more experienced observers and use some of the telescopes owned by the Society. For those who need help there is usually a naked eye sky tour to start the night off.

A comprehensive Library is available for use by all members.

The Cardiff Astronomical Society is a thriving society located in South East Wales. Come and join some of the Society's 300+ members at one of our meetings or observing sessions. Cardiff Astronomical Society promises a warm and friendly welcome for all!!
