Stellar Explosion in Earth's Proximity, Eons Ago

When the brightness of the star Betelgeuse dropped dramatically a few months ago, some observers suspected an impending supernova - a stellar explosion that could also cause damage on Earth. While ...

Lessons from a Cooling Climate

Usually, talk of carbon sequestration focuses on plants: forests storing carbon in the trunks of massive trees, algae blooming and sinking to the seabed, or perhaps peatlands locking carbon away for ...

How Earthquake Swarms Arise

A new fault simulator maps out how interactions between pressure, friction and fluids rising through a fault zone can lead to slow-motion quakes and seismic ...

Uncovering New Understanding of Earth's Carbon Cycle

A new study is examining the Earth's carbon cycle in new depth, using diamonds as breadcrumbs of insight into some of Earth's deepest geologic ...

Flood Risks: More Accurate Data Due to COVID-19

Emerging use of Global Navigation Satellite System (GNSS) makes it possible to continuously measure shallow changes in elevation of Earth surface. A study now shows that the quality of these ...

Scientists have compiled a continuous, high-fidelity record of variations in Earth's climate extending 66 million years into the past. The record reveals four distinctive climate states, which ...

Understanding Earth's 'Deep-Carbon Cycle'

New geologic findings about the makeup of the Earth's mantle are helping scientists better understand long-term climate stability and even how seismic waves move through the planet's ...

Rebirth of a Volcano

Continued volcanic activity after the collapse of a volcano has not been documented in detail so far. Now and for the first time, researchers are presenting the results of a photogrammetric data ...

New Corals Discovered in Deep-Sea Study of Great Barrier Reef Marine Park

For the first time, scientists have viewed the deepest regions of the Great Barrier Reef Marine Park, discovered five undescribed species consisting of black corals and sponges, and recorded ...

Japan's Geologic History in Question After Discovery of Metamorphic Rock Microdiamonds

Researchers have discovered microdiamonds in the Nishisonogi metamorphic rock formation in Nagasaki Prefecture, Japan. Microdiamonds in metamorphic rocks are important minerals because they form in ...

By researching tremors under the infamous San Andreas Fault, scientists are seeking out what's brewing beneath a quake's ...

To the surprise of many planetary scientists, the oxidized iron mineral hematite has been discovered at high latitudes on the ...

A new study finds that Earth's water may have come from materials that were present in the inner solar system at the time the planet formed -- instead of far-reaching comets or asteroids ...

The Le Teil Earthquake Provides New Insights on Seismic Risk in France and Western Europe

On 11 November 2019, a magnitude 5 earthquake occurred near the village of Le Teil in the Rhône River Valley in southern France producing an unexpected surface rupture with ground displacement. For ...

New research examining the crystal structure of the silica mineral quartz under shock compression is challenging longstanding assumptions about this ubiquitous ...

Two Major Microbial Groups Living Deep Underground Can't Breathe

A new scientific study has revealed unique life strategies of two major groups of microbes that live below Earth's surface. These groups, originally thought to rely on symbiotic relationships ...

A mystery surrounding the space around our solar system is unfolding thanks to evidence of supernovae found in deep-sea ...

The Age of Earth's Inner Core Revised

By creating conditions akin to the center of Earth inside a laboratory chamber, researchers have improved the estimate of the age of our planet's solid inner core, putting it at 1 billion to 1.3 ...

Greenland Ice Sheet Shows Losses in 2019

The Greenland Ice Sheet recorded a new record loss of mass in 2019. This was the finding of a team of international researchers after evaluating data from satellite observations and modelling ...

Machine Learning Unearths Signature of Slow-Slip Quake Origins in Seismic Data

Combing through historical seismic data, researchers using a machine learning model have unearthed distinct statistical features marking the formative stage of slow-slip ruptures in the earth's ...

Killer cosmic rays from nearby supernovae could be the culprit behind at least one mass extinction event, researchers said, and finding certain radioactive isotopes in Earth's rock record could ...

Earth's magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America and the southern Atlantic Ocean, an ...

Equatorial Winds Ripple Down to Antarctica

A team has uncovered a critical connection between winds at Earth's equator and atmospheric waves 6,000 miles away at the South Pole. The team has found, for the first time, evidence of a ...

Reconstructing Global Climate Through Earth's History

Accurate temperature estimates of ancient oceans are vital because they are the best tool for reconstructing global climate conditions in the past. While climate models provide scenarios of what the ...
