Abstract

Water is a crucial ingredient for the emergence of life. Therefore one of the most intriguing issues in the field of Astro-biology and Astrochemistry is to understand the origin of water on Earth. We know that our oceans contain an amount of water of about 3 tenths of a thousandth of the total Earth mass. However, if we consider also the water below the Earth crust the total amount of water could be up to 10-50 times more. There are many open questions about our precious reservoir of water, for example: When and how did water arrive on Earth? Is our planet a special case or is there water, and possibly life, also in extrasolar planets orbiting other stars in our Galaxy? With more than 1000 exoplanets discovered to date and statistics indicating that every star hosts at least one planet, the search for water in the universe is more and more urgent.
