Sunset Solstice over Stonehenge

Explanation: Yesterday the Sun reached its southernmost point in planet Earth’s sky. Called a solstice, many cultures mark yesterday’s date as a change of seasons — from autumn to winter in Earth‘s Northern Hemisphere and from spring to summer in Earth’s Southern Hemisphere. The featured image was taken just before the longest night of the 2025 northern year at Stonehenge in United Kingdom. There, through stones precisely placed 4,500 years ago, a 4.5 billion year old large glowing orb is seen setting. Even given the precession of the Earth’s rotational axis over the millennia, the Sun continues to set over Stonehenge in an astronomically significant way.

说明: 昨日，太阳到达了地球天空的最南端。这一天被称为冬至，许多文化都将昨天视为季节的更迭-地球的北半球，从秋季进入冬季，而在地球的南半球，则从春季转为夏季。这张主题影像拍摄于于2025年北半球历法中最长的夜晚到来之前，地点位于英国的巨石阵。在那里，透过4500年前精确放置的巨石，可以看到一个拥有45亿年历史的巨大发光球体正在落下。即使考虑到地球自转轴在数千年间的岁差运动，太阳仍然以具有天文意义的方式在巨石阵上空落下。
