Detective mission to characterise and trace the history of a new...

Wits researchers go on a mission to describe, classify and trace the 4.5 billion-year-old history of a meteorite that landed in Madagascar. Researchers from Wits...

The formation of large meteorite craters is unraveled

About 66 million years ago, a meteorite hit the Earth of the Yucatan Peninsula in what is now Mexico. This event triggered a mass...

Meteorite bombardment likely to have created the Earth’s oldest rocks

Scientists have found that 4.02-billion-year-old silica-rich felsic rocks from the Acasta River, Canada -- the oldest rock formation known on Earth -- probably formed...

Meteorite ‘Black Beauty’ expands window for when life might have existed...

The early surface of Mars consisting of a liquid magma ocean crystallized extremely rapidly, just 20 million year after the formation of the solar...

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...

Ingredients for life revealed in meteorites that fell to Earth

Two wayward space rocks, which separately crashed to Earth in 1998 after circulating in our solar system's asteroid belt for billions of years, share...

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

‘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
