Friday Photo: Snowflakes in Freefall

Spring has finally sprung, and so it’s possible to gaze upon snowflakes–or at least images of snowflakes–without shivering. These fine specimens were photographed in 3-D as they fell by a high-speed camera system developed by researchers at the University of Utah and its spinoff company, Fallgatter Technologies. “Until our device, there was no good instrument for automatically photographing the shapes and sizes of snowflakes in freefall,” says Tim Garrett, an associate professor of atmospheric sciences.
