60 Million Year Old Meteorite Strike in Scotland

Geologists exploring volcanic rocks on Scotland's Isle of Skye found something out-of-this-world instead: ejecta from a previously unknown, 60 million-year-old meteorite impact. The discovery,...

Meteorite analysis shows reduced salt is key in Earth’s new recipe

Scientists have found the halogen levels in the meteorites that formed the Earth billions of years ago are much lower than previously thought. The research...

Meteorites may have brought building blocks of life to Earth

Life on Earth began somewhere between 3.7 and 4.5 billion years ago, after meteorites splashed down and leached essential elements into warm little ponds,...

Large meteorite impacts drove plate-tectonic processes on the early Earth

An international study led by researchers at Macquarie University has uncovered the ways in which giant meteorite impacts may have helped to kick-start our...

Lunar dynamo’s lifetime extended by at least 1 billion years

New evidence from ancient lunar rocks suggests that an active dynamo once churned within the molten metallic core of the moon, generating a magnetic...

High-pressure experiments solve meteorite mystery

With high-pressure experiments at DESY's X-ray light source PETRA III and other facilities, a research team around Leonid Dubrovinsky from the University of Bayreuth...

‘Tiny clocks’ crystallize understanding of meteorite crashes

Almost two billion years ago, a 10-kilometre-wide chunk of space slammed down into rock near what is now the city of Sudbury. Now, scientists...

Ancient meteorite impact sparked long-lived volcanic eruptions on Earth

Meteorite impacts can produce more than craters on Earth -- they can also spark volcanic activity that shapes its surface and climate by bringing...

A new mineral from the oldest solar system solids in meteorites

Researchers have identified a new mineral in the oldest solar system solids from primitive meteorites. They've named it "rubinite" after Dr. Alan E. Rubin,...

Mega Meteorite “Largest Space Rock Ever Found in State”

UND welcomed an alien invader Friday. The 84-pound space monster was on campus for just a few hours, but it left behind a small slice...

Earth is bombarded at random

Asteroids don't hit our planet at regular intervals, as was previously thought. Earth scientists have reached this conclusion after analyzing impact craters formed in...

Evidence of 2 billion years of volcanic activity on Mars

Analysis of a Martian meteorite found in Africa in 2012 has uncovered evidence of at least 2 billion years of volcanic activity on Mars....

Rare meteorites challenge our understanding of the solar system

Researchers have discovered minerals from 43 meteorites that landed on Earth 470 million years ago. More than half of the mineral grains are from...

Did Meteorites Bring Life’s Phosphorus to Earth?

Meteorites that crashed onto Earth billions of years ago may have provided the phosphorous essential to the biological systems of terrestrial life. The meteorites...

Extraterrestrial impact preceded ancient global warming event

A comet strike may have triggered the Paleocene-Eocene Thermal Maximum (PETM), a rapid warming of Earth caused by an accumulation of atmospheric carbon dioxide...

World’s second-largest meteorite discovered in Argentina

The second-largest meteorite ever found has been exhumed outside the small Argentinian town of Gancedo. The 30-tonne rock, named after the town, was discovered on...
