Ken Freeman, Duffield Professor of the Australian National University at Mt. Stromlo Observatory and Associate of the Royal Astronomical Society has won the Australian Prime Minister's Prize for Science. Prof. Freeman published a ground-breaking paper in 1970 suggesting that the visible stars, gas and dust in galaxies is only a small fraction of their mass and that the rest is 'dark matter'.

That same year he was made an Associate of the RAS.
Prof. Freeman is awarded the Prime Minister's Prize for Science in recognition of these and his many other achievements over a career spanning 50 years.
