The anatomy of snowflakes has been studied for hundreds of years. But just what is it that makes one snowflake differ from ...

From stars to needles to amorphous globs, scientists are demystifying a snowflake’s complex construction, showing how factors ...

I like these selections of snowflake illustrations from the book Snowflakes: A Chapter from the Book of Nature by Israel Perkins Warren. These pages have the same appeal to me that a tattoo flash ...

More air pockets between snowflakes means they act like Tetris pieces and can stack a bit more. More air pockets between snowflakes means they act like Tetris pieces and can stack a bit more.

Kenneth Libbrecht, a physics professor at California Institute of Technology who has studied snowflakes for more than two decades, said snow crystals include the “star-shaped” hexagonal kind ...

That shape changes even further as they fall through the air. As each snowflake falls, it encounters water vapour in the atmosphere. This has a big effect on its shape. If humidity is low ...

Snowflakes are like letters from the sky, each crystal a note describing the atmosphere as it falls to the ground. They float effortlessly, but their creation is one of nature’s most complicated ...

The largest, most photogenic dendritic snow crystals grow best at around 5 degrees Fahrenheit, said Libbrecht, while needle and column shapes are more common around 21 degrees Fahrenheit. Each ...
