Researchers are now trying to understand the "innermost inner core" of the Earth by studying how seismic waves travel through the Earth.

Scientists drilled the deepest core yet, reaching near Earth's mantle, uncovering unique geological samples and offering new ...

Planetary scientists research the complex asteroid Vesta which may possess the same fundamental architecture as Earth such as ...

Water from both volcanic rocks and deep mantle melted Earth's crust 1.6 billion years ago. This long-lasting melting formed ...

Vesta, one of the two largest bodies in our solar system's asteroid belt, has long been thought to be more than just another ...

Separating the planet’s rocky crust and the molten outer core, the mantle makes up 70 percent of the Earth’s mass and 84 percent of its volume. But despite its outsized influence on the planet ...

Vesta, thought to be the second-largest asteroid in the solar system, could be a piece of an ancient, unknown planet, a new ...

Even the oldest and most stable of lithospheric structures can’t withstand geologic machinations deep within the Earth.

Think of them as the tough "core" of continents ... it down into the Earth's mantle. This phenomenon is gradually stripping away material from the bottom of the continent's crust.

For decades, scientists believed Vesta, one of the largest objects in our solar system's asteroid belt, wasn't just an ...

Volatiles are crucial for sustaining life and Earth's habitability, with subduction zones being the main pathways for these ...
