meteoritos palasitos parecem mel em um favo, vindos diretamente do espaço. Essas rochas são formadas por belos e translúcidos cristais verdes encrustados numa estrutura esponjosa que parece ser um favo, compostos de ferro e níquel.

When picturing a meteorite, we generally think of it as something that’s jagged with a rough texture. Reddit user Isai76, however, recently shared something unexpected - a polished meteorite! In addition to the photo, fellow Redditor fewthe3rd explained what makes this polished piece so special. It’s technically a pallasitic meteorite, and the green-yellow transparent minerals are called olivine, which composes most of the upper mantle of the Earth. The metallic parts are an iron-nickel alloy.
