Scientific Rationale:

The Symposium we plan to organize will summarize the current status of Extremely Large Telescopes (ELT, GMT, TMT), their instrumentation and the planned early science. Emphasis will be given to the key role that different flavors of Adaptive Optics systems are going to play during operations (GLAO, SCAO, MCAO, MOAO).

Moreover, we will discuss the impact that near future ground-based and space observing facilities will have on several long-standing Astrophysical problems, ranging from the characterization of extrasolar planets to resolved and unresolved stellar populations, to galaxy formation and evolution, to fundamental constants and to reionisation and cosmology.

Special attention would be given to the synergy with observing facilities operating in different wavelength regimes. Finally, we also plan to organize, during the Symposium, a one-day Teacher Training Workshop. Moreover, we also plan to organize – the week after the IAU GA – an International School for Master/PhD students and for young researchers focussed on current and future observing facilities.
