Scientists from the University of Southern California (USC) have confirmed that the Earth’s inner core is rotating more slowly than the planet’s surface. This significant finding, published in Nature, reveals that the inner core began to decelerate around 2010, overturning previous beliefs about its rotational dynamics. For decades, the scientific community has debated the movement […]

Researchers Decode One of the Greatest Environmental Disasters in Earth’s History, the “Carnian Crisis”
The study, published in Scientific Reports, reveals astonishing details about how the global climate changed 233 million years ago, leading to a massive extinction in the seas of the Mesozoic era. The global “Carnian Crisis”, which lasted for two million years (from 234 to 232 million years ago), left its mark on the rocks of […]

Researchers find the Oldest Undisputed Proof of Earth’s Magnetic Field: 3,7 Billion Years Old
Researchers from the University of Oxford and the Massachusetts Institute of Technology (MIT) have made an important discovery about the history of Earth’s magnetic field. They found the oldest clear evidence that Earth had a magnetic field, dating back 3.7 billion years. This is a significant finding that helps us understand more about the ancient […]

Researchers Discover Previously Unknown Process in Tectonics that Turns Seafloor into Mountains
Scientists use tiny minerals called zircons as geological clocks. These crystal grains, often the size of sand, record the chemical signals of the geological environment they formed in. In a new study led by scientists at the University of Texas at Austin, researchers used them to describe what may be a missing step in a […]

Ancient Submerged Island the Size of Spain Found off the Coast of Brazil
A study led by scientists at the University of São Paulo (USP, Brazil) has shown that the Rio Grande Rise (RGR), a possible continental basaltic plateau and seamount chain now submerged in the South Atlantic Ocean about 1,200 km off the coast of Brazil, was once a giant tropical island, rich in minerals and covered […]

Murchison Meteorite Contains the Oldest Material Ever Found on Earth
On September 28, 1969, an extraordinary event shook the tranquility of the small town of Murchison, Australia. At 10:58 in the morning, local time, a meteorite crashed near the town, scattering fragments over an area of approximately 13 square kilometers. Scientists quickly mobilized to collect over 100 kg of scattered fragments, the largest being about […]

Scientists Discover the Base of a 100-Meter-High Star-Shaped Dune in Morocco Dates Back 13,000 Years
Scientists have finally solved the mysterious absence of star-shaped sand dunes in the geological record of Earth’s history, managing to date one of these dunes back thousands of years. This study, conducted by scholars from the universities of Aberystwyth, Birkbeck, and UCL, is the first to pinpoint just how long it took for a stellar […]

The Largest Underwater Volcanic Eruption in History, 7300 Years Ago in Japan, Created a Caldera the Size of a Capital City
A team of geoscientists from Kobe University recently uncovered evidence that a massive volcanic eruption that took place 7,300 years ago in southern Japan was the largest eruption to occur on Earth within the past 11,700 years. Their findings shed new light on mega-eruption dynamics and the influential role volcanoes have played in Earth’s climate […]

Geologists Find First-Ever Evidence of a Devastating Ancient Tsunami in an Inland Sea
Hundreds of millions of years ago, a massive earthquake rattled the earth, sending towering waves crashing across an ancient tropical sea that covered part of present-day Canada and the United States. This startling conclusion comes from new research by two University of Saskatchewan scientists, who uncovered startling evidence of ancient tsunamis wreaking havoc in this […]
