Astrophotographer Paul Zizka sent in this photo of an aurora with a special guest, taken at the Minnewanka boat docks, Banff National Park, Canada, on Oct. 8, 2012. He writes: When this shot was taken I was perhaps not the most thrilled photographer. It was the second night in a week that I went chasing the auroras all night, and they were hidden somewhere behind a veil of clouds (as you can tell from the surreal sky), even though the rest of the country seemed to be seeing them. It turns out that I was completely unaware that I was taking one of my most memorable shots. This morning I noticed a visitor [had] made his way into the frame, and I could not believe my eyes. The owl is surprisingly sharp in this 5-second exposure. Thanks to the Minnewanka boat docks for lighting the bird perfectly, and to Mother Nature for providing the perfect perch and background.
