“This image is a cathodoluminescence picture of a chondrule from a primitive meteorite. Chondrules are small melt droplets consisting of silicate minerals such as olivine and pyroxene (pink grains), along with glass (green-blue material between the pink grains). The presence of chondrules tells us that this is a primitive meteorite – one that came from an asteroid that formed around 4.5 billion years ago, and has remained unmelted ever since. Cathodoluminescence images such as this one can provide information on the trace elements present in the sample, which in turn provides information about conditions in the early solar system”.

TEM image of a sarcocyst embedded within snake muscle. The grayscale TEM image has been colorized to highlight the developing metrocytes (orange) which will eventually develop into mature bradyzoites (blue). Sarcocysts can only be identified to species based on TEM analysis of the patterns of the cyst wall (black). Image courtesy: Joe Mowery – USDA ARS
“Life is a Puzzle” By Jim Kilcrease 2015 MSA Micrograph Contest Winner An artistic rendition of a confocal image of a leaf.
LT-SEM image of the “Coffee Drinking Mite”, by CMMS member Gary Bauchan from USDA ARS, won second place in the 2018 MSA micrograph competition.
LT-SEM image of a hexagonal dendritic snow crystal captured by William Wergin and Eric Erby at USDA ARS. One of the first images of a snowflake captured using a SEM. Pseudocolored
TEM image of a baculovirus OpbuNPV occlusion body from the larvae of the winter moth, Operophtera brumata. Occlusion bodies are consumed by moth larvae, and dissolved in the midgut which releases the virions to infect the host’s midgut epithelium. Pseudocolored.
