Light pillars form when a bright light (from the sun, the moon or man-made light sources) reflects off the surfaces of millions of falling ice crystals associated with thin, high-level clouds. The pillars, which are often mistaken for UFO sightings, are typically seen in polar regions and they might lengthen or brighten as you gaze at them.
Photographer Jay Callaghan shot the beautiful photo below, on his back deck in 25 February at 1:45 am , as he was looking northeast toward Chemong Road in Peterborough, Ontario.
The crows that live in Tokyo build their nests out of metal clothes-hangers. In such a large city, there are few trees, so the natural materials that crows need to make their nests are scarce. As a result, the crows steal hangers from the people who live in apartments nearby, and carefully assemble them into nests. The completed nests almost look like works of art based on the theme of recycling. Continue reading →
Lake Natron takes its name from natron, a naturally occurring compound made mainly of sodium carbonate, with a bit of baking soda (sodium bicarbonate) thrown in. Here, this has come from volcanic ash, accumulated from the Great Rift valley. Animals that become immersed in the water die and are calcified.
Photographer Nick Brandt, while in Tanzania, discovered perfectly preserved birds and bats on the shoreline. “I could not help but photograph them,” he says. “No one knows for certain exactly how they die, but it appears that the extreme reflective nature of the lake’s surface confuses them, and like birds crashing into plate glass windows, they crash into the lake.”
The rare phenomenon occurs each winter in the man-made lake, Abraham Lake, located at the foot of the Rocky Mountains. Bubbles are created as the plants on the lake bed release methane gas, which freezes as it comes closer to the cold lake surface. That is, until spring comes and the ice starts to thaw.
