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 continues to provide 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 which, we were pleased to see, was named University of the Year at the 2017 Business and Education Partnerships Awards. 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!

Introduction to Geology

Please note that the National Museum Cardiff is repeating its successful 'Introduction to Geology' course. It will be held on successive Thursday afternoons (1.30 - 4.00 p.m.) in March 2018 - for five weeks. Each session will consist of an illustrated talk by one of the Museum's geologists followed by a chance to handle and discuss relevant Museum specimens.

The aim will be to introduce participants to the basics of geology: from the structure of the Earth, geological time, the rock-cycle, rock structures, rock types (sedimentary, igneous and metamorphic), minerals and fossils. The course will end with a stroll through the geological history of Wales. No previous knowledge of geology is expected, and you'll be encouraged to ask questions and discuss ideas. The cost is just £65 for the course of five sessions, including illustrated handouts for each week.
