Chondrites are the likely building blocks of Earth, and identifying the group of chondrite that best represents Earth is a key to resolving the state of the early Earth. The […]

Potassium Isotope Compositions of Carbonaceous and Ordinary Chondrites
Solar system materials are variably depleted in moderately volatile elements (MVEs) relative to the proto-solar composition. To address the origin of this MVE depletion, we conducted a systematic study of […]
Ancient Meteorite Site On Earth Could Reveal New Clues About Mars' Past
Scientists have devised new analytical tools to break down the enigmatic history of Mars’ atmosphere — and whether life was once possible there. A paper detailing the work was published […]
Potassium Isotopic Compositions Of Enstatite Meteorites
Enstatite chondrites and aubrites are meteorites that show the closest similarities to the Earth in many isotope systems that undergo mass-independent and mass-dependent isotope fractionations. Due to the analytical challenges […]
Tiny, Ancient Meteorites Suggest Early Earth's Atmosphere Was Rich In Carbon Dioxide
Very occasionally, Earth gets bombarded by a large meteorite. But every day, our planet gets pelted by space dust, micrometeorites that collect on Earth’s surface. A University of Washington team […]
Meteorite Contains The Oldest Material On Earth: 7-billion-year-old Stardust
Stars have life cycles. They’re born when bits of dust and gas floating through space find each other and collapse in on each other and heat up. They burn for […]
A Meteorite's Story of Complex Planetary Processes
A recent study has revealed new details about the composition and fragmentation of a meteorite reportedly discovered in the deserts of southwestern Morocco in 2012. Researchers examined fragments from the […]
Tracing Meteorites to the Solar Nebula
A recent study on the isotopic compositions of the South Byron Trio iron meteorite grouplet (SBT) shows that all three meteorites likely came from a single parent body that formed […]
The Meteorite Flux of the Last 2 Million Years Recorded in the Atacama Desert
The evolution of the meteorite flux to the Earth can be studied by determining the terrestrial ages of meteorite collected in hot deserts. We have measured the terrestrial ages of […]
Clues To Delivery of Water to Earth From Carbonaceous Chondrites
An international study led by researchers from the Institute of Space Sciences, from the Spanish National Research Council (CSIC) and the Institut d’Estudis Espacials de Catalunya has discovered that carbonaceous […]
