Ancient species may have evolved more slowly and lasted longer, but the pace of evolution picked up after global ice ages, according to a new study from Virginia Tech. Published in the journal Science, the research traces the rise and fall of ancient life—long before the age of dinosaurs. If we think of the Earth […]

The Newly Formed Earth Was a Dry and Hot Place: A Theory Explains How Water Arrived Here and on Other Planets of the Solar System
A group of scientists from the Paris Observatory has proposed a new theory about how water arrived on Earth, a key question for understanding the emergence of life on our planet. The study, published in the journal Astronomy and Astrophysics, suggests an innovative mechanism that could change our view of Earth’s past and that of […]

How the Mediterranean Lost So Much Water 5.3 Million Years Ago That Its Level Was 1 Kilometer Below the Atlantic Ocean
A recent study led by a CNRS scientist analyzed the significant drop in the Mediterranean Sea level during the monumental geological event known as the Messinian Salinity Crisis. This event, which occurred between 5.97 and 5.33 million years ago, transformed the Mediterranean into a massive salt reservoir. Until recently, the way in which approximately one […]

Easter Island findings change everything we know about the Earth’s mantle and how it moves beneath the crust
Traditionally, textbooks have described the mantle as a viscous, well-mixed layer that shifts along with tectonic plates, much like a conveyor belt. This theory has been a cornerstone of geology for nearly a century but has been notoriously difficult to prove. Now, a study by geologists from Cuba, Colombia, and the Netherlands is challenging that […]

Microorganisms discovered living hundreds of meters deep in Greenland 75 million years ago
A recent international study, led by Associate Professor Henrik Drake from Linnaeus University, has uncovered groundbreaking evidence that microorganisms lived deep beneath Greenland’s rocky surface 75 million years ago. This research offers new insights into the history of the “deep biosphere”, a hidden world of life existing far beneath the Earth’s surface. The deep biosphere […]

Earth Had a Ring Like Saturn’s for Millions of Years, and Its Shadow Triggered an Ice Age
A recent study published in the journal Earth and Planetary Science Letters reveals evidence that Earth may have had a ring similar to Saturn’s around 466 million years ago, during the Ordovician period. The research team, led by Andrew G. Tomkins from Monash University in Australia, reached this surprising conclusion after meticulously analyzing the geographical […]

A massive undersea avalanche devastated the northwest coast of Africa 60,000 years ago
A study from the University of Liverpool has unveiled the colossal scale and devastating impact of a massive underwater avalanche that struck the northwest coast of Africa some 60,000 years ago. This research, published in Science Advances, provides unprecedented insights into the magnitude and destructive force of submarine avalanches, a phenomenon shrouded in mystery until […]

Over the last 700 million years, the distance between the Earth and the Moon has increased by 20,000 kilometers, and the days have lengthened by 2.2 hours
A team of scientists from Chengdu University, led by academic Wang Chengshan, has published a study in the renowned journal Proceedings of the National Academy of Sciences (PNAS), the result of an international collaboration involving experts from institutions such as the Paris Observatory, the Leibniz Institute for Applied Geophysics in Germany, and Trinity College in […]

The Earth Hasn’t Lost a Continent, but Has Gained a Microcontinent
In recent days, many media outlets have been citing a study published recently in the journal Gondwana Research to argue that North America and Europe should be considered a single continent, and therefore Earth would have one less than previously established. However, the study actually says nothing of the sort. On the contrary, it argues […]

Scientists Achieve Deep-Sea Drilling Milestone, Recovering Longest Section of Mantle Rocks
In a groundbreaking achievement, a team of international scientists has successfully retrieved a significant section of rock from the Earth’s mantle, marking a new era in the study of our planet’s inner workings. The mantle, located beneath the Earth’s crust and constituting the largest part of the planet, holds key secrets about the origins of […]
