The Milky Way and its Stars

Studies of Galactic and stellar structure are entering an era replete with data from large space- and ground-based projects. The combination of large photometric surveys carried out in the last 15 years, extensive photometric-variability databases allowing the inner structure of thousands of stars to be studied, and vast high-resolution spectroscopic surveys probing the detailed chemical composition of hundreds of thousands of stars, hold the promise of a new synthesis of stellar and Galactic astrophysics. These data will in a few years be complemented by precise astrometric measurements from Gaia.

The Cosmic Distance Scale

Understanding the distance scale has always been central to astronomy, and its determination has been a multi-pronged pursuit. More than two decades ago the distance scale was uncertain by a factor of two, and the resolution of this conundrum had been a major driver for HST. Today a wealth of new cosmological measurements from both the local and the high redshift Universe are reaching a precision of a few percent, with further improvements on the horizon. Better knowledge of the distance scale has profound impacts in areas ranging from stellar astrophysics to the cosmological model. We believe that now is an excellent time to discuss what has been learned and what we can expect to learn in the near future.
