Eric Formo’s “Planet #1” won the grand prize in the 2017 Image Contest sponsored by Thermo Fisher Scientific. Formo, manager of UGA’s Georgia Electron Microscopy Lab, gathered micrometeorites—extraterrestrial dust particles, including fragments of comets and asteroids—from building rooftops in Athens. He identified micrometeorites in the 5-to-500-micron range via high-resolution imaging and elemental analysis, then verified authenticity based on their morphologies and elemental compositions. In “Planet #1,” the central microsphere has been colored to resemble an inhabited planet like Earth, although the surrounding smaller materials are the actual micrometeorites.
