ESO Workshop, ESO Headquarters, Garching, Germany, 19–22 January 2015
This workshop will provide a forum for discussion of the likely astronomical landscape in the 2020s - both core science and burning topics, in so far as these can ever be predicted. Flowing from these considerations, the community is invited to advise the ESO Executive with regard to future facilities, including, but not limited to, those at the existing optical/infrared observatories on La Silla and Paranal, at the sub-millimetre observatories APEX and ALMA on Chajnantor and at the European Extremely Large Telescope to be built on Cerro Armazones.
