Lenticular Cloud at Sunset 

Each day, NASA’s Astronomy Picture of the Day (APOD) offers “a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer”. While I often skip over these in my daily reading of the entire Internet from beginning to end, Monday’s post was bizarre enough to catch my eye.

Though it ruined the photographer’s intended shot, this cloud gave him an image that looks unreal. Be sure to visit the site to see the full-sized image.
