Half a century of X-ray Astronomy

In 2012, we are celebrating the 50th birthday of X-ray astronomy. This year finds the XMM and Chandra missions quite mature after 12 years in orbit. These have produced a wealth of exciting results ranging from accretion physics to cosmology. In 2012 the first results from the long awaited Nustar mission will be presented, while the final preparations for the launch of the SRG/eROSITA mission are taking place. We are organising a conference in Mykonos, Greece, in order to celebrate this occasion. The topics of this conference cover the full range of X-ray Astronomy from X-ray surveys, AGN and clusters to galaxies as well as accreting objects in our Galaxy. Although our aim is to cover a broad range of topics, we will attempt to make sure that the maximum synergy between the sessions is achieved
