Using a special camera that captures images in 1-40,000th of a second (vs. about 1-200th for normal cameras), scientists have captured images of snowflakes as they fall, revealing fascinating images quite unlike what we’re used to seeing.
My favorite thing about these images is that you can see the three-dimensional structure of some of the flakes. I caught the story from a short article on ScienceMag.org, but the University of Utah also has a gallery.
