Aberdeen Astronomical Society welcomes you to join them for Neville Brown’s account of the building of the three great observatories of Yerkes, Mount Wilson and Palomar and the driving force behind them – the American astronomer George Ellery Hale. At Mount Wilson he hired and encouraged Edwin Hubble, and he himself discovered magnetic fields in sunspots. You can find out more about the Society from their website http://www.aberdeenastro.org.uk
