SAEDNEWS: A Composite Panorama of a Year’s Sunsets from April 2023 to March 2024
According to the Science Service of Saed News, the maximum northern (right side of the image) and southern deviations of the sun over the course of a year correspond to the summer and winter solstices, respectively. The term “solstice” comes from Latin, meaning “sun” and “to stop.” As seen in today’s NASA image, during a solar solstice, the sun’s seasonal movement in the sky appears to pause and then reverse direction in its annual journey.
Today, the sun reached its winter pause position. This year’s winter solstice occurred on December 21 at 09:21 UTC (12:51 Iran time). This moment marks the sun’s greatest southern deviation, signaling the start of astronomical winter in the Northern Hemisphere and astronomical summer in the Southern Hemisphere.

These seasonal changes in the sun’s path result from the Earth’s axial tilt, which is angled at 23.4 degrees relative to its orbit around the sun. This phenomenon directly affects the length of days, the intensity of sunlight, and seasonal weather patterns. The winter solstice marks the shortest day of the year in the Northern Hemisphere and the longest day in the Southern Hemisphere. Images captured in this project not only illustrate the sun’s apparent movement but also highlight the importance of seasonal changes and their impact on human life and nature.
