Textures and colors of igneous rocks (in this case martian meteorites) under a microscope can be esthetically extraordinary. In Spring 2017, I (Arya Udry) participated to the Inquiry: The Art of Scientific Discovery exhibition at UNLV organized by Jason Steffen (UNLV Department of Physics and Astronomy), which displayed work from throughout the UNLV College of Science.
We presented a cross polarized image of the Nakhlite Miller Range 090032 (see below) borrowed from NASA ANSMET collection at Johnson Space Center. This image displays euhedral to subhedral clinopyroxene with twinning formed by shock metamorphism during impact on Mars, and fayalitic olivine (see Udry et al., 2012 for petrogenesis and composition of this meteorite and pairs).
