Anticrepuscular Rays
Here’s a brief observation: These rays (at the right side of the panoramic picture above, and in the photo below) are viewed toward the horizon opposite the direction of the sun. More details about the phenomena are with the picture below. What is interesting is that they appear to converge at the horizon, even though they do not actually converge. In fact, the rays, being generated from a light source 93 million miles away, are parallel to each other. But the curve of the earth and perspective of an earth-bound viewer leads to the impression that there are convergent points at each horizon with the rays bowing out to diffusion in the middle—just above the observer. Usually, there is not continuity between the two horizons, so it actually appears that there is a convergence at the horizon(s) and divergence or dissipation where the observer is.
The difference between the parallel reality and convergent/divergent appearance is similar to what all of life looks like to believing but earth-bound observers. There may be faith that God was completely in control at Creation. There may be confidence that God will bring everything back together in the future. But where most people live there is a sense that God may not be keeping it all together. Of course, believers know better in their heads. But the world still looks as if it has diverged from God’s plan and purpose. The rays in the pictures make a handy reminder that regardless of pressures, pains, failures, and frustrations appearing over our heads, God’s plan, purpose, and power are as arrow-straight above our heads as they are at our beginning and our end.
Explanation (From APOD, Astronomy Picture of the Day): 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.
