Cool Sunsets from Around the Heart of Illinois

Last week, we had some incredible sunrises and sunsets around the area. The clouds in the morning and evening help create beautiful colors in the sky thanks to the curvature of the earth. Here are a few of my favorite pictures that were sent in to our facebook page.

Like I mentioned, these elaborate colors that fill the sky before sunrise or after sunset are due to the curvature of the earth and the way our eyes perceive light. We perceive the light of differing wavelengths as different colors. Red typically has the longest wavelength and is seen immediately after a sunset before the darker colors with smaller wavelengths occupy the sky. When the sky has clouds on the horizon, they help scatter that remaining reds and pinks from the setting or rising sun. This helps create incredible images like these.

As the sun continues to set, the wavelengths get reduced and the color changes to blue and violet which have the shortest wavelength. So next time you enjoy a beautiful sunrise, you’ll know some science as to what causes the incredible colors in the sky.
