The latest evidence for the common presence of water in our solar system, which may eventually explain how so much of it collected on Earth. The spacecraft Dawn, led by an investigator here at UCLA, will be the first probe to study the protoplanet Ceres up close and will arrive in 2015. Where there is water, there is life... Interestingly enough, biomolecules have been found along with traces of water inside asteroids, with new theories of magnetism and solar system formation showing that the spread of water may be a typical process given the properties of young stars and the protoplanetary plasma that surrounds them.

Ceres, the largest asteroid in the solar system, lets off steam
Twin jets on asteroid Ceres, which has a surface area roughly the same as India, release 21 tonnes of water vapour every hour
