A full-field hard-x-ray microscope at SSRL with 15 micron field of view and 40 nm resolution, as well as 3D tomographic capabilities, has successfully imaged samples of biological, environmental and astronomical origin. Spectroscopic imaging of a particle of comet dust from the NASA Stardust mission showed significantly more absorption contrast above the Fe K-edge, and tomography revealed the three-dimensional structure of the terminal particle and track through the aerogel.
