Research news on meteorite

A meteorite, as a substance, is solid extraterrestrial material that has survived passage through Earth’s atmosphere and reached the surface, typically classified into stony (chondrites and achondrites), iron, and stony-iron types based on mineralogical and chemical composition. Chondritic meteorites preserve primitive nebular components such as chondrules and refractory inclusions, often with CI-like bulk solar abundances for nonvolatile elements. Iron meteorites consist predominantly of Fe-Ni alloys (kamacite and taenite) and may exhibit Widmanstätten patterns reflecting slow cooling in differentiated parent bodies. Meteorites are key samples for cosmochemistry, isotopic dating, and constraining early Solar System processes and planetary differentiation.

New device aims to protect the Earth from Martian microbes

The possibility of life on other planets is one of the biggest mysteries in science. But what would happen if we actually found it? Our scientists are preparing for this possibility by helping to develop a new system that ...

Neutron scans reveal hidden water in famous martian meteorite

New tools unlock new discoveries in science. So when a new type of non-destructive technology becomes widely available, it's inevitable that planetary scientists will get their hands on it to test it on some meteorites. A ...

Meteorite samples are time capsules from the early solar system

When a meteor streaks across the sky, it's not just beautiful. It's nature's way of delivering a time capsule to Earth. Contained within are hints about the very beginning of the solar system and how planets, including our ...
