Our Sun and planetary system were born about 4.5 billion years ago. How did this happen,
and what is the nature of our heritage from these early times? This review tries to address …

The concentration and distribution of water in the Earth has influenced its evolution
throughout its history. Even at the trace levels contained in the planet's deep interior (mantle …

The past two decades of lunar exploration have seen the detection of substantial quantities
of water on the Moon's surface. It has been proposed that a hydrated layer exists at depth in …

Water is a fundamental molecule in the star and planet formation process, essential for
catalysing the growth of solid material and the formation of planetesimals within disks …

Earth's water, intrinsic oxidation state and metal core density are fundamental chemical
features of our planet. Studies of exoplanets provide a useful context for elucidating the …

As the search for Earth-like exoplanets gathers pace, in order to understand them, we need
comprehensive theories for how planetary atmospheres form and evolve. Written by two well …

There is a long-standing debate regarding the origin of the terrestrial planets' water as well
as the hydrated C-type asteroids. Here we show that the inner Solar System's water is a …

One popular view of Venus' climate history describes a world that has spent much of its life
with surface liquid water, plate tectonics, and a stable temperate climate. Part of the basis for …

Cometary nuclei consist mostly of dust and water ice. Previous observations have found
nuclei to be low-density and highly porous bodies,,, but have only moderately constrained …

" The study of planet formation has a long history. The idea that the Solar System formed
from a rotating disk of gas and dust-the Nebula Hypothesis-dates back to the writings of …
