5 月 7 日,太陽從教堂鐘樓後面落下,被地球上西西里島拉古薩的這張經過過濾和處理的數字天景圖捕捉到。在這個版本的影像中,色彩看起來非常怪異。不過,一種被稱為 "殘像 "的有趣視錯覺可以幫助你以更自然的外觀體驗同樣的場景。要嘗試一下,請在藍色太陽圓盤底部附近找到活動區 AR 4079 的太陽黑子群。放鬆並凝視黑暗的太陽黑子群約 30 秒鐘,然後閉上眼睛或將視線轉移到純白色的表面上。頃刻間,日落的殘影應該會隱約出現。不過,殘像日落將具有該影像的互補色,在熟悉的藍天映襯下,太陽會呈現出更正常的黃色。
原文: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.
