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,...

Discovery about rare nitrogen molecules offers clues to makeup of life-supporting...

A team of scientists using a state-of-the-art UCLA instrument reports the discovery of a planetary-scale "tug-of-war" of life, deep Earth and the upper atmosphere...

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...

Collisions after moon formation remodeled early Earth

Southwest Research Institute scientists recently modeled the protracted period of bombardment following the Moon's formation, when leftover planetesimals pounded the Earth. Based on these...

Ice shapes the landslide landscape on Mars

How good is your Martian geography? Does Valles Marineris ring a bell? This area is known for having landslides that are among the largest...

Water On Mars? : Previous evidence of water on Mars now...

Dark features previously proposed as evidence for significant liquid water flowing on Mars have now been identified as granular flows, where sand and dust...

Moon’s crust underwent resurfacing after forming from magma ocean

The Earth's Moon had a rough start in life. Formed from a chunk of the Earth that was lopped off during a planetary collision,...

Space dust may transport life between worlds, research suggests

Life on our planet might have originated from biological particles brought to Earth in streams of space dust, a study suggests. Fast-moving flows of interplanetary...

Site of asteroid impact changed the history of life

An asteroid, also known as the Chicxulub Impactor, hit Earth some 66 million years ago, causing a crater 180 km wide. The impact of...

Formation of magma oceans on exoplanet

Induction heating can completely change the energy budget of an exoplanet and even melt its interior. In a study published by Nature Astronomy an...

Microbes Leave “Fingerprints” on Martian Rocks

At the Department of Biophysical Chemistry at the University of Vienna, Tetyana Milojevic and her team have been operating a miniaturized "Mars farm" in...

Study shows how water could have flowed on ‘cold and icy’...

For scientists trying to understand what ancient Mars might have been like, the red planet sends some mixed signals. Water-carved valleys and lakebeds leave...

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...

Dino-killing asteroid could have thrust Earth into two years of darkness

Tremendous amounts of soot, lofted into the air from global wildfires following a massive asteroid strike 66 million years ago, would have plunged Earth...

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...

Hot rocks, not warm atmosphere, led to relatively recent water-carved valleys...

Present-day Mars is a frozen desert, colder and more arid than Antarctica, and scientists are fairly sure it's been that way for at least...

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...

Rover findings indicate stratified lake on ancient Mars

A long-lasting lake on ancient Mars provided stable environmental conditions that differed significantly from one part of the lake to another, according to a...

‘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...
