I previously wrote a post about capturing snowflakes on a high-speed camera. But now scientists are using super-chilled microscopes to study the geometric shapes and patterns of ice crystals!

Researchers at the Beltsville Agricultural Research Center in Maryland used an electron microscope, super-cooled all the way down to -170 degrees Celsius to capture stunning images of the snowflakes. The photographs show hexagonal structures, grain structures, and crystalline branches.

Check out the images here:
