Past Photos


Parhelion: Sun dog

This is a photo of a parhelion grouping (from the Greek para=beside, and helios=sun,), a phenomenon commonly known as a sun dog. It occurs when the sun’s rays shine through ice crystals in the upper atmosphere, refracting the light and creating arcs. Sun dogs most frequently appear on either side of the sun, but spectacular variations can occur with more arcs.

Stemonitis splendens: Chocolate tube slime mold

This organism begins its life cycle as white blobs of slime spreading across rotting wood. But only a few hours later, it transforms by sprouting tiny tubes covered with chocolate-colored spores. Slime molds, like their distant fungi cousins, are crucial links in the chain of decomposition, breaking down dead organisms to create nutrients and new habitat in the ecosystem.
