When an Allende stone is sawed into two pieces and the surface is polished, the structure in the interior can be examined. This reveals a dark matrix embedded throughout with mm-sized, lighter-colored chondrules, tiny stony spherules found only in meteorites and not in earth rock (thus it is a chondritic meteorite). Also seen are white ...
The Allende meteorite has shown to be full of new minerals, after nearly forty years it has produced one in ten of the now known minerals in meteorites. [2] This CV3 carbonaceous chondrite was the largest ever recovered on earth and is referred to as the best-studied meteorite in history. [2] The inclusion has only been viewed via electron ...
Anders went on to study samples of the Allende meteorite, the largest carbonaceous chondrite ever found on Earth. Results of these studies suggested elements 111–115 (today roentgenium, copernicium, nihonium, flerovium, and moscovium) [4] as the most likely candidates for the progenitor of CCF Xe.
The space rock that slammed into Earth 66 million years ago at the end of the Cretaceous Period caused a global calamity that doomed the dinosaurs and many other life forms. Researchers assessed ...
The giant meteorite caused a tsunami to sweep across the planet, the scientists found. Heat from the impact caused the topmost layer of the ocean to boil off, while also heating the atmosphere.
Shortly after its fall and recovery in Australia in 1969, the Murchison meteorite was found to host five protein amino acids (glycine, alanine, valine, proline, and glutamic acid) in addition to 12 non-proteinogenic amino acids including α-aminoisobutyric acid and isovaline, which are rare on Earth.

The Winchcombe meteorite is a rare and pristine carbonaceous chondrite, and it likely holds clues about early Earth's composition—and where our water came from.
