Astrophoto: Stunning Alaskan Sun Pillar


Cold enough for you? Jason Ahrns captured this brilliant Sun pillar, “reaching down into the trees just below the Geophysical Institute, University of Alaska Fairbanks on a nice -40 C (or F — its all the same) day,” Jason said.

A Sun (or solar) pillar is a vertical shaft of light extending upward or downward from the Sun, and are typically seen in cold weather when sunlight reflects off the surfaces of falling ice crystals associated with thin, high-level clouds.

Jason used a Nikon D7000 camera.
