The Search for Dark Matter by Professor Carolin Crawford

Unlike the stars and galaxies, dark matter does not give off any radiation – we can only detect it through its gravitational pull. It accounts for a quarter of the Universe, yet we do not yet understand what it is made of. The search for a better understanding of dark matter is carried out both out in space and deep underground, and where astrophysics meets particle physics. (from gresham.ac.uk)
