1. Researchers at the Beltsville Agricultural Research Center in Maryland used an electron microscope super-cooled to -170 degrees Celsius to capture some rarely seen views.
2. This photo of a snow grain under intense magnification may help hydrologists determine the winter snow pack content.
3. This amazing close up shows one tiny snowflake as a hexagonal shape with some crystalline structures forming along its rim.
4. A snowflake at the microscopic level looks much like an ‘ordinary’ flake you might catch a glimpse of during a cold winter snowfall.
5. Electron microscopy at sub-zero temperatures helps scientists at the Beltsville Agricultural Research Center learn more about the structure
6. Researchers capture naturally occurring flakes and then quickly dip them in liquid nitrogen to keep them from melting.
7. Under the super-cooled electron microscope, amazing detail about ice crystals is revealed.
8. This extremely close-up view of a snowflake after several days in a snowpack shows signs of rounding at the edges.
9. The electron microscopy revealed the many different shapes on a snowflake.
