2021 Fall Date Project

The MPOD Caretakers want to present meteorite falls on their fall dates. For example, Sikhote Aline on 12 February.

This Project will not dip into the MPOD archives so the Caretakers will appreciate anything you can contribute.

To reserve a date just let us know. Thank you in advance :)

The Chondrule That Thought It Was a Holiday Ornament

Imagine a holiday season fir tree decorated with identical ornaments.

Imagine these ornaments change their color as you walk around it or, maybe, they change their color as the tree rotates and you are stationery. Some of these images show the latter.

Some petrographic microscopes (i.e., polarized light) around the early 1890's were equipped with a bar that coupled the polarizer and analyzer together, and rotated simultaneously while keeping the stage with sample in a fixed position - the equivalent of you walking around the tree.

Happy Holidays!
