Aims & Scope

Water consists up of the two most common reactive elements in the Universe. Does it mean it exists everywhere in the Universe? How and where is it formed and destroyed? What roles does it play under different circumstances? Where did Earth's water form and how did it arrive here?

Although atmospheric water vapour constitutes only ~0.001% of all 'surface' water on Earth, which is but ~0.02% the total mass of the Earth, it makes ground based astronomical observations of water exceedingly difficult. Space missions have played a key role, and today water has been observed in gaseous and solid form in various environments under a range of physical conditions throughout our solar system, in disks around young stars, in proto-stars, in the interstellar medium in star-forming clouds in our galaxy, and in external galaxies including also in high-redshift galaxies in the early universe.

This meeting will cover all astrophysical aspects of water. Topics are meant to be wide in scope, and include the following broad science areas:

• Formation and destruction of water and its chemistry: theory, laboratory work, and models
• Water excitation and its relation to other ISM tracers
• Water in star formation 
• Water in disks and planet formation
• Water in the solar system and exo-solar systems 
• Extra-galactic and high-redshift water 

The objective of the meeting is to bring together astronomers interested in all astrophysical aspects of water, from the solar system to extra-galactic high-z conditions. The meeting aims to facilitate cross-fertilization between researchers with different observational, experimental, and theoretical backgrounds.
