太阳总是从同一个方向升起吗？否。随着月份的变化，太阳升起的方向也会改变。这张特色图片显示了2021年加拿大艾伯塔省埃德蒙顿市每个月的日出方向。图像中的摄像机始终面向正东，左边是北，右边是南。如图所示，上面的图像拍摄于2020年12月，下面的图像拍摄于2021年12月，总共有13张图像。虽然太阳通常从东方升起，但在12月至日附近，太阳在东方最南边升起，在6月至日附近，太阳在东方最北边升起。在许多国家，冬至被认为是季节的正式变化：例如在北方，冬至是冬天的第一天。在冬季，地球表面和大气中的太阳能加热和储存能量接近最低水平，使冬季成为一年中最冷的季节。状态更新：部署詹姆斯·韦伯太空望远镜

Does the Sun always rise in the same direction? No. As the months change, the direction toward the rising Sun changes, too. The featured image shows the direction of sunrise every month during 2021 as seen from the city of Edmonton, Alberta, Canada. The camera in the image is always facing due east, with north toward the left and south toward the right. As shown in an accompanying video, the top image was taken in 2020 December, while the bottom image was captured in 2021 December, making 13 images in total. Although the Sun always rises in the east in general, it rises furthest to the south of east near the December solstice, and furthest north of east near the June solstice. In many countries, the December Solstice is considered an official change in season: for example the first day of winter in the North. Solar heating and stored energy in the Earth's surface and atmosphere are near their lowest during winter, making the winter season the coldest of the year.
