Days and nights arrive and leave. What do a year's worth of them look like when combined?

In 2021, a skycam took a photo of the skies overhead every 15 minutes and then, I assume, powerful computers took over and created a picture of the entire year. It is revealing and provided me a new way to think about the overhead, e.g., as a dark hour glass embedded in a palette of fading blues.

The image is featured, with an explanation, on Astronomy Picture of the Day (APOD). Run your cursor across it to read the labels
