It feels like there have been staggering science stories emerging every other day recently, all of which have blown our tiny little minds. First, there was the discovery of a terrifying black hole ...

Other hidden water sources within Earth’s crust While the ringwoodite-bound ocean is undoubtedly the most significant discovery, it’s not the only hidden water source within our planet.

Our new results provide the strongest evidence yet that at least some Halley-type comets carried water with the same isotopic ...

Water is constantly leaking through Earth's crust and toward the outer core as tectonic plates subduct under one another, while magma rises via a similar pathway in the opposite direction.

A new analysis of ancient grains of crystal embedded in rock from the Australian outback suggests Earth had dry land and fresh water some 4 billion years ago — a time when scientists had thought ...

For starters, despite looking like a shapeless solid, ice is actually made up of multiple nanoscopic crystals, all of which are only a few billionths of a meter across, if that.

Water leaking into the Earth may be wrapping the core in crystals, a study has suggested. The study may help explain a weird area in the outer core that has long puzzled scientists.

But what is revealed deep inside the Earth surprises laymen and scientists alike: Almost 3000 kilometers below the Earth's surface, solid rock is flowing that is neither liquid, like lava, nor ...

Determining when water first appeared, where, and for how long, are all burning questions that drive Mars exploration. If Mars was once habitable, some amount of water was required. My colleagues and ...

Earth's solid inner core may not be solid after all — at least not all the way through. Instead, it’s a hodgepodge patchwork of solid and liquid that reaches all the way to the center.

Earth may have had fresh, not just salty, water as soon as 600 million years after the planet formed — a mere blink of an eye in geologic time.
