  Water is perhaps the most important molecule in our Solar System. Figuring out where it came from and how it was distributed within and among the planets can help scientists understand how planets formed and evolved. New research from a team including Carnegie’s Erik Hauri demonstrates that water from the interiors of the Earth [continue reading]
