December 22 is the first day of winter for all the folks in the Northern Hemisphere! The sun is the furthest away from the equator, shining directly over the Tropic of Capricorn (Alice Springs, Australia and Sao Paulo, Brazil are just a couple of cities along the Tropic of Capricorn.) The first day of winter is the shortest day of the year (meaning it gets dark pretty darn early)!

Antarctica is the coldest place on earth (kind of a no-brainer here) with the coldest reported temperature being -89.4 C (or) -129 F.

Snowflakes are really ice crystals in various patterns.
According to the International Commission on Snow and Ice (seriously), snowflakes have these general forms:
- Stellar crystals
- Spatial dendrites
- Capped columns
- Irregular forms
Some snowflake researchers use 35 shapes.
The world’s largest snowflake was 38 cm wide and 20cm thick and was found at Fort Keogh, Montana on January 28, 1887.
The most snowfall within 24 hours in the U.S. was 63 inches and occurred in Georgetown, Colorado on December 4, 1913.
