Muonionalusta is a rare and scientifically significant iron meteorite that fell in northern Sweden, with some fragments dating back over a million years. It is classified as an ataxite iron meteorite known for its unique Widmanstätten pattern – a distinctive intergrowth of kamacite and taenite crystals visible when a polished surface is acid-etched. This pattern reveals the slow cooling history of the metal core of a differentiated asteroid that the meteorite originated from. Meteorite slices like this one, weighing 78.9 grams, are highly prized by collectors and researchers alike for their extraterrestrial origin and stunning metallic luster. The Muonionalusta meteorite, discovered in the early 20th century, is renowned for its role in advancing the study of meteoritics, particularly the understanding of metal crystallization in space objects. Pieces such as this provide a tangible connection to our solar system's history and the processes shaping planetary bodies.
