500 posts and I guess it is time for a new image. (And I guess a short science lesson....;^)
This photograph was taken through a microscope of a thin section (glass slide) of the Camel Donga meteorite. Camel Donga is a monomict Eucrite class meteorite, that was found during 1984 on the Nullurabor Plain of Western Australia. Originally 12 stones totalling 2.92 kg. were found. However, further searchers recovered many additional stones. The meteorite is composed of mostly proxene and plagiocase, with ~2% iron. A very high amount of iron for eucrites.
The thin section is shown under crossed polar lights, which makes various minerals glow in different colors. This is also how earth rocks are studied. A eucrite, like most achondrite meteorites, looks a lot like a typical earth basalt rock.

Yes it is, but I must admit I did not take the photograph. My set up is homemade, and that was taken through a much more professional scope/camera set up by a friend.
I have a pretty nice thin section collection including lunar and martian meteorite slides. The achondrites (think surface rocks from the larger bodies in space) are my favorite.
