This iron meteorite was originally found in Harriman, Tennessee, USA and is now held in the collection of the Smithsonian Natural History Museum, Washington DC, USA. The total mass of the meteorite was about 30kg. Here we see the interior after the meteorite was cut into pieces.
Iron meteorites are largely composed of an iron-nickel. They also often have a crystalline structure which manifests here as a series of crossing shiny straight lines known as a Widmanstätten pattern. This is thought to have formed as the meteoroid (the object that would eventually fall through the Earth's atmosphere as a meteor and land on the ground as a meteorite) cooled very slowly in the vacuum of space in the early solar system. This led to the growth of this crystalline structure.

图片说明 Dieser Eisenmeteorit wurde ursprünglich in Harriman, Tennessee, USA, gefunden und befindet sich heute in der Sammlung des Smithsonian Natural History Museum, Washington DC, USA. Die Gesamtmasse des Meteoriten betrug etwa 30 kg. Hier sehen wir das Innere, nachdem der Meteorit in Stücke geschnitten wurde.
Eisenmeteoriten bestehen größtenteils aus einer Eisen-Nickel-Legierung. Sie weisen auch oft eine kristalline Struktur auf, die sich hier als eine Reihe sich kreuzender glänzender gerader Linien zeigt, die als Widmanstätten-Muster bekannt sind. Man nimmt an, dass sich dieses Muster bildete, als der Meteoroid (das Objekt, das schließlich als Meteor durch die Erdatmosphäre fiel und als Meteorit auf der Erde landete) im Vakuum des Weltraums in der Frühzeit des Sonnensystems sehr langsam abkühlte. Dies führte zum Wachstum der sichtbaren kristallinen Struktur.

图片说明 Questo meteorite di ferro è stato trovato originariamente a Harriman, nel Tennessee (USA), ed è ora conservato nella collezione dello Smithsonian Natural History Museum, a Washington DC (USA). La massa totale del meteorite era di circa 30 kg. Qui vediamo l'interno dopo che il meteorite è stato tagliato in pezzi.
I meteoriti di ferro sono composti in gran parte da ferro-nichel. Spesso presentano anche una struttura cristallina, che qui si manifesta con una serie di linee rette lucide che si incrociano, note come motivo Widmanstätten. Si pensa che si sia formato quando il meteoroide (l'oggetto che alla fine attraverserà l'atmosfera terrestre come meteora e atterrerà al suolo come meteorite) si è raffreddato molto lentamente nel vuoto dello spazio nel primo sistema solare. Ciò ha portato alla crescita di questa struttura cristallina.
