The Cupid Coach - Ep 6 - One of the rare moments that makes this show bearable

Microscope photo taken at 15X of the Seymchan iron/pallasite meteorite from Magadan District, Russia. Photo is a cut, polished and acid etched slice of the iron facies of this meteorite fall. The slice displays the classic Widmanstatten pattern (a.k.a. Thomson structure) found in some iron-nickel meteorites. This pattern results from the interweaving of crystals from two iron alloys, kamacite (low nickel) and taenite (high nickel). The Widmanstatten pattern is diagnostic of meteorites as this pattern cannot be duplicated in laboratories on Earth. To form this pattern the iron core of the asteroid must cool no faster than a couple of degrees every million years. In the gaps between the lamellae, a fine-grained mixture of kamacite and taenite called plessite can be seen. The "sausage-looking" features are the naturally formed iron crystals.

Muonionalusta iron meteorite from Norrbotten , Sweden. Structural class is fine octahedrite. Weight 84 grams. Photo is a cut, polished and acid etched slice of a single meteorite.
