The Origin of the Most Part of Water on the Earth, and the Reason why there is More Water on the Earth than on the other Terrestrial Planets
The origin of water on the Earth, and the reason why there is more liquid water on the Earth than on the other terrestrial planets of the Solar System is not completely understood. Here we show thatExpand


Hydrogen Isotopes in Lunar Volcanic Glasses and Melt Inclusions Reveal a Carbonaceous Chondrite Heritage
Results demonstrate that lunar magmatic water has an isotopic composition that is indistinguishable from that of the bulk water in carbonaceous chondrites and similar to that of terrestrial water, implying a common origin for the water contained in the interiors of Earth and the Moon. Expand
A low mass for Mars from Jupiter’s early gas-driven migration
Simulation of the early Solar System shows how the inward migration of Jupiter to 1.5 au, and its subsequent outward migration, lead to a planetesimal disk truncated at 1’au; the terrestrial planets then form from this disk over the next 30–50 million years, with an Earth/Mars mass ratio consistent with observations.
