Allende meteorite

The Allende meteorite, a CV3 carbonaceous chondrite, fell near Pueblito de Allende in Chihuahua on February 8, 1969, after a brilliant fireball crossed the sky and exploded. As the largest carbonaceous chondrite found on Earth, it produced one of the largest known strewnfields, and more than two tonnes of material were recovered over decades. Its abundant fresh specimens made it the best-studied meteorite in history and a benchmark for meteoritics. Allende contains ancient calcium-aluminium-rich inclusions, chondrules, presolar grains, and unusual isotopic signatures that helped reshape understanding of the Solar System’s earliest history and suggested material from older stars and possibly a nearby supernova.
