In the late 1800s, researchers Wilson Bentley and Gustav Hellmann began photographing snowflakes. Each of their photos revealed different representations of snowflakes. How could nature present so many forms of snowflakes? Today, scientists are solving that mystery with the use of a camera system that photographs free-falling snowflakes.
