IAA - Another brilliant talk!

This fortnight's IAA talk was given by Professor Alan Fitzsimmons of QUB who is part of the team which has built the world's largest digital camera weighing in at over 1.3 Gigapixels! It's the Pan-STARRS project. This is the camera attached to a telescope on top of Mauna Kea Mountain in Hawaii and will, when it's finished, be capable of locating and imaging Solar System Objects down to 140m in diameter and will form part of the early warning system which will tell us about Near Earth Objects which may hit the Earth.

Alan's talk was delivered in a lively, enthusiastic and very informative style which had me gripped from start to finish.
