RAS200 project resources (communicating science through the medium of art) RAS200 Sky and Earth is an ambitious plan to celebrate the bicentenary of the Royal Astronomical Society. They aim to embed and provide a legacy of astronomy and geophysics in the wider society. RAS200 in Wales aims to raise awareness of astronomy and geophysics through the arts activities of the Urdd and National Eisteddfod. This collection provides resources developed as part of the activity. There are presentations of astronomy and geophysics through culture, which provide an insight into the science through creative works. To learn more about the project, read Professor Eleri Pryse's introduction to RAS200 in Wales.

The paper investigates the structure and behaviour of the nighttime ionised (electrified) atmosphere in the polar and auroral regions; the region where the aurora borealis occurs. Of particular interest are plasma structures on horizontal scales of hundreds of kilometres. The observations presented were made by the radiotomography experiment of the University of Wales, Aberystwyth, which has four satellite receiving systems in the high Arctic near the north pole, at Ny Ålesund and Longyearbyen on Svalbard, Bjørnøya (Bear Island) and Tromsø on mainland Norway. Comparisons of tomography images with observations of plasma flow by the international SuperDARN radar suggest that large density plasma produced on the dayside flows across the polar region and into the night sector. The results contribute to the interpretation of physical processes that couple the Earth's environment with space, and are also of interest to users of radio systems where the ionised atmosphere can degrade the propagation of the signals.

This resource contains six packages of resources relating to the basic core principles of Mathematics and Physics. They include problems and solutions, with the aim of increasing the Welsh terminology in the subjects and raising students' confidence in dealing with the subjects in Welsh. There is a set of examples and theory and practical exercises for each of the six topics covered.
