Water, Water, Every Where — And Now Scientists Know Where It Came From
The blue planet’s blue parts are a great mystery because the origin of water on earth has never been concretely determined. A new study provides evidence that the water has been here all along and was a constituent in the building blocks.
A new study in the journal Science suggests that the Earth likely got a lot of its precious water from the original materials that built the planet, instead of having water arrive later from afar.
The researchers who did this study went looking for signs of water in a rare kind of meteorite. Only about 2% of the meteorites found on Earth are so-called enstatite chondrite meteorites. Their chemical makeup suggests they’re close to the kind of primordial stuff that glommed together and produced our planet 4.5 billion years ago.
