The natural world is filled with sights that often seem as mysterious as they are beautiful. At first glance, this might appear to be a UFO cruising over Wyoming.
In actuality, it's a lenticular cloud, as Mark Meyer, writing for the Astronomy Picture of the Day explained in 2003:
Is that a cloud or a flying saucer? Both, although it is surely not an alien spacecraft. Lenticular clouds can be shaped like a saucer, and can fly in the sense that, like most clouds, they are composed of small water droplets that float on air. Lenticular clouds are typically formed by high winds over rugged terrain and are particularly apparent when few other clouds are in the sky. Lenticular clouds can take on particularly strange, layered shapes. A couple stopped near Yellowstone National Park in Wyoming to photograph this lenticular cloud behind picturesque windmills.
As the links above show, lenticular clouds are enchanting sights that mimic what people perceive as UFOs or, often, motherships. Recently, I'd written about an exploding "octopus" over England that ripped apart a wind turbine.
I'd theorized that the structure had gotten hit by ball lightning, but UFO expert Nick Pope disagreed. The material from that encounter is under analysis.
UFOs or natural phenomena? Paranormal Examiner Melissa Alvarez poses that question in "Did space aliens attend the inauguration of Barack Obama?".
I'm voting for "something natural." I suspect a big bird, most likely an eagle swooping though the sky.
Because sometimes, there's nothing more spectacular than the simple miracles of everyday life on Earth.
