A Look Inside a Meteorite

Ever wonder what a meteorite looks like inside? These image were made in cross-polarized light, where a polarizer between the light source and the microscope slide is rotated. The beautiful effect, called birefringence, causes the colors of the crystals in the meteorite’s minerals to change, creating amazing colors, as the polarizer is rotated.

Astronomers and planetary geologists study meteorites in thin section to determine their material makeup. The colors and angles of refraction of the light through the crystals help identify the crystals. Some of the material inside meteorites are quite likely as old as, or older than, the Earth itself.

1,2) The Allende meteorites (named after a pueblito in Mexico called Allende where they fell in 1969) contain interstellar dust particles which are thought to be the oldest unaltered particles in our Solar System.

3) This meteorite is called NWA 4292 and was found in the Sahara Desert in Africa in 2005.

Review for khalyeezy12085

While I loved Hew and her absolutely perfect contrasting apparel, I had to go with Starfall! I am not in arcane just for the awesome space dad. Space and stars are a huge fascination for me and I personally also have several dragons themed like that. Starfall just makes me want to get a exact clone of him. He is not dressed besides the accent and that makes him look like a real galaxy? The maize smoke gives the impression of milky ways in the depths of space and just… wow. Also i saw his Clan Role will be Astronomist? I can’t imagine who would be better suited than him!
