“A Year in Sunsets” is copyrighted by Wael Omar. NASA has permission to show it and we don't, so it isn't on this card.
See it on NASA's siteA year of sunsets, from April 2023 to March 2024, tracks along the western horizon in these stacked panoramic views. This sequence was constructed from images recorded near the 21st day of each month, from the same location overlooking Cairo, Egypt. For any location on Earth, the yearly extreme northern and southern limits of the setting Sun mark the solstice days. The word solstice comes from Latin for "Sun" and "stand still."
