Meteorite diamonds tell of a lost planet

Using transmission electron microscopy, EPFL scientists have examined a slice from a meteorite that contains large diamonds formed at high pressure. The study shows...

Water appeared while Earth was still growing

Up until about ten years ago, scientists thought they had a pretty good picture of how the moon and Earth came to co-exist. Then...

Brewing up Earth’s earliest life

Around 4 billion years ago, Earth was an inhospitable place, devoid of oxygen, bursting with volcanic eruptions, and bombarded by asteroids, with no signs...

Understanding the Earth under Hawaii

In the 1960s, some 50 years after German researcher Alfred Wegener proposed his continental drift hypothesis, the theory of plate tectonics gave scientists a...

Argonne’s powerful X-rays key to confirming water source deep below Earth’s...

A study published in Science last week relies on extremely bright X-ray beams from the U.S. Department of Energy's (DOE) Advanced Photon Source (APS)...

Diamonds from the deep: Study suggests water may exist in Earth’s...

Water on Earth runs deep - very deep. The oceans have been measured to a maximum depth of 7 miles, though water is known...

Unique diamond impurities indicate water deep in Earth’s mantle

A UNLV scientist has discovered the first direct evidence that fluid water pockets may exist as far as 500 miles deep into the Earth’s...

Do you know where your xenon is?

The paradox of the missing xenon might sound like the title of the latest airport thriller, but it's actually a problem that's stumped geophysicists...

New data helps explain recent fluctuations in Earth’s magnetic field

Using new data gathered from sites in southern Africa, University of Rochester researchers have extended their record of Earth's magnetic field back thousands of...

Giant lava dome confirmed in Japan’s Kikai Caldera

Since the Kobe Ocean Bottom Exploration Center (KOBEC) was established in 2015, it has carried out three survey voyages to the Kikai Caldera, south...

Challenging core belief: Have we misunderstood how Earth’s solid center formed?

It is widely accepted that the Earth's inner core formed about a billion years ago when a solid, super-hot iron nugget spontaneously began to...

Earth’s mid-life crisis – new research backs ‘lull’ in the geologic...

New research backing claims that the Earth experienced a 'geological lull' in its development around 2.3 to 2.2 billion years ago has just been...

Oxidized iron deep within Earth’s interior

Scientists digging deep into the Earth's mantle recently made an unexpected discovery. Five hundred and fifty kilometres below the Earth's surface, they found highly oxidized...

Earth’s core and mantle separated in a disorderly fashion

Plumes of hot rock surging upward from the Earth's mantle at volcanic hotspots contain evidence that the Earth's formative years may have been even...

Heat loss from the Earth triggers ice sheet slide towards the...

Greenland's ice sheet is becoming smaller and smaller. The melting takes place with increased strength and at a speed that no models have previously...

New details emerge on temperature, mobility of earth’s lower crust in...

Everything on the surface of the Earth rests on massive tectonic plates that resemble a jelly sandwich, with two rigid pieces -- the upper...

Between the lines: Tree rings hold clues about a river’s past

Hydrologists are looking centuries into the past to better understand an increasingly uncertain water future. By analyzing centuries-old growth rings from trees in the Intermountain...

Which came first: Complex life or high atmospheric oxygen?

We and all other animals wouldn't be here today if our planet didn't have a lot of oxygen in its atmosphere and oceans. But...

Computing the way to the center of the Earth

In order to more fully comprehend the complexities of Earth's interior, humanity has to dig deep -- literally. To date, scientists have been able...

Ancient weakening of Earth’s crust explains unusual intraplate earthquakes

New research reveals that mysterious pockets of earthquake activity in the middle of North America all have one thing in common: Earth's crust in...
