The inside of a Meteorite. "Fun fact: Widmanstätten patterns found inside meteorites cannot be replicated on Earth. This is because the patterns can only be formed in extremely slowly cooling nickel/iron mixtures (over millions of years) to form two different alloys: Taenite and Kamacite, that form slightly different crystal structures." #meteorite

Exploring Universe: The Pistol Star: A Brilliant Star in Milky Way's Core

Chinguetti, Mesosiderite type meteorite from Mauritania weight 370.5g Mesosiderites are enigmatic mixtures of metal and igneous rock. Catastrophic collisions more than four billion years ago may explain this unexpected mingling of nickel iron alloy from the core and rock from the surface of one or more large asteroids. The coarse Widmanstätten structures in the metal suggest that it cooled very slowly, probably because the rock metal mixture was deeply buried following melting and mixing.

Chaque jour, environ 100 tonnes s’ajoutent à la masse de la Terre en raison de différentes chutes de météorites. Parfois, tombées quelque part parmi les météorites ordinaires, on en trouve une bien plus rare que les autres: La météorite pallasite. Les météorites pallasites sont des joyaux d’esthétisme et de science. Elles ne représentent pas plus d’un pour cent des chutes.
