Stellar Dendrite
Created | Updated Feb 11, 2007
The word stellar means "starlike" and the word dendrite means "treelike". The largest of these crystals appear around -15° when humidity is high, and a generously sized one might be about 3mm in diameter although larger ones can be found. Their formation is caused by a process called "Branching Instability".
Here is a link to a photograph Stellar Dendrite, found by researcher "rcc-when life moves on i will move on = )"
, and originally taken by Ken Libbrecht.
