Anticrepuscular Rays Over Colorado

Explanation: What’s happening over the horizon? Although the scene may appear somehow supernatural, nothing more unusual is occurring than a setting Sun and some well placed clouds. Pictured above are anticrepuscular rays. To understand them, start by picturing common crepuscular rays that are seen any time that sunlight pours though scattered clouds. Now although sunlight indeed travels along straight lines, the projections of these lines onto the spherical sky are great circles. Therefore, the crepuscular rays from a setting (or rising) sun will appear to re-converge on the other side of the sky. At the anti-solar point 180 degrees around from the Sun, they are referred to as anticrepuscular rays. Pictured above is a particularly striking set of anticrepuscular rays photographed in 2001 from a moving car just outside of Boulder, Colorado, USA.

    5. Depressing. How come *I* have never seen an amazing sky like that? I won’t believe these skies really exist until I see one with my own eyes.

    6. Is that Jesus coming over the hill? Jesus. I say it’s Jesus!

      You see things like this in mountainous areas, particularly on cloudy days, but this particular image is one hell of an example. I’ve never seen a display quite that dramatic myself.

      Why do you attribute this to science? Because they used a clumsy but impressive word to describe it? This is a natural phenomenon, merely explained by science.
