5月7日，太阳落在教堂钟楼后面，这幅经过过滤和处理的数字天空景观拍摄于地球上西西里岛的拉古萨。在这个版本的图像中，颜色看起来很奇怪。尽管如此，一种有趣的视错觉被称为后像，可以帮助你以更自然的外观体验相同的场景。为了尝试，找到活跃区域AR4079的太阳黑子，这些黑子聚集在蓝色太阳圆盘的底部附近。放松，盯着黑暗的太阳黑子群30秒左右，然后闭上眼睛或将目光转移到一个普通的白色表面。过一会儿，夕阳的余影就会隐约出现。但后像的日落将有这张照片的互补色和一个更正常的黄色太阳与熟悉的蓝色天空。

On May 7, the Sun setting behind a church bell tower was captured in this filtered and manipulated digital skyscape from Ragusa, Sicily, planet Earth. In this version of the image the colors look bizarre. Still, an intriguing optical illusion known as an afterimage can help you experience the same scene with a more natural looking appearance. To try it, find the sunspots of active region AR4079 grouped near the bottom of the blue solar disk. Relax and stare at the dark sunspot group for about 30 seconds, then close your eyes or shift your gaze to a plain white surface. In a moment an afterimage of the sunset should faintly appear. But the afterimage sunset will have this image's complementary colors and a more normal yellow Sun against a familiar blue sky.
