2015 is the International Year of Light, a celebration of the central role that light has played in our understanding of the Universe.
Dr. Hammond described the preparation involved in organising projects and events that will celebrate the importance of light and its effects, from photography and lasers to art and how it has helped in our understanding of the universe.
Dr. Hammond described a proposal to involve amateur astronomers worlwide taking part in an experiment to emulate that udertaken by Ole Roemer in 1676 to determine more accurately the speed of light by observations of the eclipsing moon Io. A lot of interest was shown by members and some will probably get involved as more details are made available.
