中秋节

今天是中秋节，是桂花浮玉的时节，是月满天街的日子。图片中的风景是位于中国贵州省贵阳市的甲秀楼，甲秀楼始建于明朝万历二十六年（1598年），取“科甲挺秀”之意，设有浮玉桥衔接两岸。此时满月映照了整个苍穹，夜空如洗，甲秀楼和周围的古建筑在明月与灯光的映衬下，投射在湖水中，颇有“书画一船烟外月，湖山十里镜中人”的意境。

您知道吗？民间中秋赏月活动约始魏晋时期，盛于唐宋。如今的人们依然会进行赏月活动。在家中庭院、餐厅聚会，摆出月饼瓜果等，边赏月边畅谈，其乐融融。中秋佳节，让我们以月寄情，盼生活更加美好，康乐，幸福。

Mid-Autumn Festival

As summer's warmth gently yields to autumn's cool embrace, the Mid-Autumn Festival lights up the Chinese city of Guiyang, celebrating the full moon and the autumn harvest. Also known as the Moon Festival, it takes place on the 15th day of the year's eighth lunar month in the Chinese calendar.

The harvest has been celebrated around the autumn full moon since China's Shang dynasty, more than 3,000 years ago. During the festival, families reunite to enjoy delectable mooncakes, admire the beauty of the moon, express gratitude, and tell tales of Chang'e, the Chinese goddess of the moon, and her husband Hou Yi, a legendary archer.

Similar festivals are celebrated in Japan, Vietnam, South Korea, and other countries in East and Southeast Asia. Jiaxiu Tower, pictured on our homepage, was built in 1598, so it has witnessed many Mid-Autumn Festivals. Under the moonlit sky, lanterns adorn the tower, illuminating the streets, symbolizing hope, good fortune, and unity.

世界海事日

大海是一个充满野性又混乱的“工作场所”，考虑到约80%的国家会进入海洋发展，因此，国际海事组织在1948年日内瓦举行的联合国会议上初步建立，并于10年后正式生效成立。为了纪念第一次会议，每年九月，海事工作者会聚集在一起庆祝世界海事日。这个活动提高了人们对海事安全、航运的可持续发展以及环境保护的意识。除此之外，这一天也是向海上的无名英雄——海事工人致敬的日子。

今年的主题是纪念《73/78 防污公约》发布50周年，这是一部管理船舶排放，防止海洋环境污染的国际法。海洋在全球贸易中扮演着重要的角色，同时，地球上许多物种的生存（包括人类）都依赖于一个健康的海洋环境，因此，保护海洋环境，人人有责。

World Maritime Day

The sea is a tough workplace, and a busy one—the shipping industry is the backbone of the global economy, transporting more than 80% of the world’s trade. On World Maritime Day, shipping professionals and leaders gather to raise awareness about maritime safety, sustainable shipping practices, and pollution. Organized by the International Maritime Organization, a UN agency, the day also honors maritime workers. These unsung heroes work long hours and spend months away from family to keep our trade flowing.

This year's theme focuses on the 50th anniversary of MARPOL 73/78, an international law that regulates emissions and aims to minimize pollution in our ocean waters. While the ocean plays a vital global role in trade, the survival of many species on Earth, including our own, depends on it remaining a healthy place.

克虏伯路，卡普里，意大利

克虏伯路是意大利卡普里岛上一条历史悠久的道路，以其不同寻常的蛇形设计而闻名于世。它修建于1900年至1902年，由德国实业家克虏伯出资建造，道路将卡普里镇和玛丽娜·皮科拉海滩连接起来，当年，克虏伯就是通过这条小路去巡视他的产业。克虏伯路布局错综复杂，转弯急促，坡度陡峭，是当时的工程奇迹。站在路上眺望远方，你可以看到第勒尼安海、法拉廖尼悬崖以及卡普里岛上郁郁葱葱的景观。凭借这些美景，克虏伯路吸引了无数游客前来打卡观赏。不过，由于落石造成的安全隐患，这条小路曾间歇性关闭，但在今年6月，它又重新开放了，这是九年来的首次开放。

Via Krupp, Capri, Italy

Via Krupp is a cliffside pathway on the Italian island of Capri, renowned for its dramatic serpentine design. Built between 1900 and 1902 by the German industrialist Friedrich Alfred Krupp, the footpath connects the town of Capri to Marina Piccola beach, and allowed Krupp to access his properties. The pathway's intricate layout, with its sharp turns and steep inclines, was an engineering marvel of its time. Via Krupp's panoramic vistas of the Tyrrhenian Sea, the Faraglioni rock formations, and the lush landscape of the island have drawn admiration for generations. Due to concerns over preservation and safety, because of falling rocks, the pathway has faced intermittent closures, though it reopened in June this year for the first time in nine years.

世界河川日

如果你是一个喜欢大自然的环保倡导者，喜欢听河流的轰鸣声，那么，今天的世界河川日一定不要错过。继2005年至2015年联合国“生命之水”
国际行动十年之后，加拿大保育生物学家马克·安杰洛（Mark
Angelo）提出了一项保护河流的全球性活动。自2005年起，联合国将每年9月的第四个星期日定为世界河川日，旨在关注和保护河流的环境、文化及生态。

今天图片的主角，弗雷泽河，是不列颠哥伦比亚省最长的河流，也是加拿大第11长的河流。这条河的源头位于落基山脉，蜿蜒穿越超过854英里的坡地和平原，最后汇入温哥华以南的乔治亚海峡。

World Rivers Day

If you are a nature enthusiast, or simply enjoy listening to the sound of rumbling rivers, you might like to know that today is World Rivers Day. First held in 2005 during the United Nations' 'Water for Life’ campaign, it was proposed by Canadian river conservationist Mark Angelo, who founded BC Rivers Day in western Canada in 1980. World Rivers Day is held on the fourth Sunday of September to celebrate and raise awareness of the benefits that rivers provide to people and the planet.

The star of today's image, the Fraser River, is the longest river in British Columbia and the 11th longest in Canada. The stream meanders from the Rocky Mountains, traveling more than 850 miles over slopes and flatlands before it merges with the Strait of Georgia, just south of Vancouver.

沐浴在秋天的色彩中 Awash in autumn hues

秋分

秋天正式开始了！在北半球，今年的9月23日是秋分，这一天标志着秋天开始，太阳直射地球赤道，白昼和黑夜相等。在南半球，同样如此，但南北半球的季节是相反的，北半球秋分，南半球则是春分，正在迎接春天的到来。

在今天的图片中，这棵隐身于秋色中的棉白杨可能正在红砂岩中玩“躲猫猫”。郊狼谷位于犹他州南部的格兰峡谷国家保护区，由于水和其他液体的氧化作用，以及含铁矿物质的存在，峡谷呈现出红橙色。

Autumnal equinox

Autumn has officially begun! In the Northern Hemisphere, the autumnal equinox falls on September 23 this year, marking the beginning of autumn. Today is one of the two moments in the year when day and night are equal in length, thanks to the sun's location exactly above the equator. In the Southern Hemisphere, today marks the vernal equinox and they are heading into spring.

Camouflaged in autumn colors, the cottonwood tree in today's image might be playing peek-a-boo among the red sandstones of Coyote Gulch in southern Utah. Here in the Glen Canyon National Recreation Area, the canyon is painted orange by oxidizing water and other fluids, as well as iron-filled minerals.

马尔萨拉，西西里岛的奇迹之一

马尔萨拉盐田，意大利

韦尔东大峡谷位于普罗旺斯的中心，是欧洲独一无二的自然奇观。马尔萨拉的斯塔尼奥内湖，自1995年起成为保护区，占地约1000公顷，是古代时期的重要盐产地。马尔萨拉盐田历史悠久，由腓尼基人在公元前1000年左右建立。如今，这个美丽的地方由世界自然基金会管理，保护着定期迁徙到马尔萨拉地区的众多鸟类。

在诺曼人统治时期，盐田已经广为人知，这种珍贵资源的生产与贸易建立了国家垄断，这要归功于斯威士兰的弗雷德里克二世于1861年颁布的法令。随着意大利的逐渐统一，这些盐田“躲过”了被垄断，它们是少数没有被国家垄断，从而将盐出口到世界各地的盐田。你可以通过多种方式欣赏这些壮丽的景色。比如单独看看风车、体验主题博物馆，或者跟随导游参观，了解更多关于盐田的文化知识。

渡槽，阿卡迪亚公园，波兰

阿卡迪亚公园位于波兰华沙附近，是由波兰贵族海伦娜·拉齐维乌设计的英式景观公园。公园的建筑和景观沾染着古代和中世纪的气息，比如这个仿造的罗马风渡槽。园内郁郁葱葱的绿植、宁静的流水以及精雕细琢的雕塑等，都诠释着公园的自然与艺术交融之美。今天，我们依旧可以透过阿卡迪亚公园，看到海伦娜·拉齐维乌不朽的艺术构想。

Aqueduct, Arkadia Park, Poland

Founded in 1778 by aristocrat Helena Radziwiłłowa, Arkadia Park is an English-style landscape park in central Poland. The park displays architecture and landscapes that evoke ancient and medieval eras, like this recreation of a Roman-style aqueduct. These features are brought to life by the garden's lush greenery, tranquil water, and intricately crafted sculptures throughout the grounds, which illustrate the beauty of intermingled nature and art. Today, Arkadia Park stands as a testament to Helena Radziwiłłowa's lasting vision and creative legacy.

不要因为泥泞的道路就停下您踏上哈德良长城步道的脚步。这条设立于2003年的国家级步道位于英格兰北部，自东向西蜿蜒了84英里。

步道不远处沉睡着罗马的防御工事遗迹——哈德良长城。罗马帝国征服不列颠后，皇帝哈德良下令修建长城。哈德良长城位于英格兰北部，从北海至索尔威湾，绵延70多英里，是英国的文化象征，是一处世界遗产，也是英国最大的古罗马遗迹。

秋季天文周

美国一年里有两次天文日，分别是春季天文日（4月中旬到5月中旬）和秋季天文日（9月中旬至10月中旬）。在这个特别的节日，科学博物馆、天文台、天文俱乐部和天文馆将举办专业人士主持的讲座、展览和工坊活动。对夜空的科学观测从早期文明时代就开始了，而天文学被称为最早的自然科学学科，是研究天体及相关现象的学科。今天照片里的是葡萄牙的西南阿连特茹和维森廷海岸自然公园，这里远离光污染，是个观星的好地方哦。

Fall Astronomy Week

The Milky Way has billions of stars; among them, our own sun finds its place. The galaxy's name is derived from the radiant, pale appearance of the band of stars and gas clouds that graces Earth's sky. Methodical observations of the night sky started with early civilizations but astronomy, the oldest natural science, remains a source of fascination today. It's what brings stargazers to Portugal's Southwest Alentejo and Vicentine Coast Natural Park, a site free from heavy light pollution. Now's a good time to seek out your own celestial spectacle, as it is Astronomy Week and the main event, Saturday's Fall Astronomy Day, this year coincides with the autumnal equinox.

施布吕根山口，瑞士

今天的照片展示的是位于勒蓬廷阿尔卑斯山脉上的一条公路线——施布吕根山口。山口位于瑞士和意大利的边境，海拔6936英尺，其蜿蜒的山路是欧洲海拔最高的公路之一。虽然现代的施布吕根山口建于1818-1823年，但其历史可追溯至罗马时代。自从1967年附近的圣贝纳迪诺公路隧道开通后，这个山口就变得安静多了。如今，这条有着51个急转弯的公路会在冬季保持关闭。因此，如果您想去一览壮观的山景、体验惊险的山路旅程，可以将行程定在6月至10月中旬哦。
