Episode Details

In ancient times, a blood moon was considered an omen, its copper glow instilling a sense of foreboding in people who felt it signaled an impending disaster. Today, however, huge advancements in the study of astronomy have meant the occurrence of the celestial event is eagerly awaited by astronomy enthusiasts and ordinary people alike, all keen to witness and document its rare beauty.

在古代，“血月”被视为一种不祥之兆，其铜红色的光辉让人们心生不安，认为这预示着灾难即将来临。然而如今，天文学研究的巨大进步使得这一天象备受天文爱好者和普通民众的热切期待，人们都渴望亲眼见证并记录下这一罕见的美景。

From 11:30 pm on Sunday to 5 am on Monday, this year’s first and only blood moon visible in China captivated stargazers across the country. Some leaned out of windows to stare at the sky, while others set up professional equipment to capture the spectacle.

从周日晚上11点30分到周一凌晨5点，中国境内今年首次也是唯一一次可见的“血月”吸引了全国各地的观星者。有人探出窗外仰望天空，也有人架设专业设备捕捉这一壮观景象。

Tang Haiming, a researcher at the Chinese Academy of Sciences’ Shanghai Astronomical Observatory, said that a blood moon occurs during a total lunar eclipse when Earth aligns between the sun and the moon, casting its shadow over the moon. Colors with longer wavelengths make it through Earth’s atmosphere and make the moon appear orangish or reddish. The moon displays different shades of red depending on atmospheric conditions, he added.

中国科学院上海天文台研究员、上海市天文学会秘书长汤海明表示，“血月”出现在月全食期间，此时地球运行至太阳与月球之间，将阴影投射到月球上。波长较长的光线能够穿透地球大气层，使得月球呈现出橘红色或红色。他补充道，月球具体呈现出何种红色调，会因大气条件的不同而有所差异。

Tang, who is also secretary-general of the Shanghai Astronomical Society, said the blood moon was observed not only in Asia, but also in the Eastern Atlantic, Oceania, the Indian Ocean, Europe, Africa, the Western Pacific and Antarctica.

汤海明还指出，此次“血月”不仅在亚洲可见，在东大西洋、大洋洲、印度洋、欧洲、非洲、西太平洋以及南极洲地区也能观测到。

“The blood moon is a normal astronomical phenomenon. During a total lunar eclipse, the gravitational forces of the moon and the sun combine and can lead to astronomical tides. However, there is no need to panic. Many people from Shanghai went to the Qiantang River to see the tide,” Tang said.

汤海明表示：“‘血月’是一种正常的天文现象。月全食期间，月球和太阳的引力共同作用，可能会引发天文大潮，但无需恐慌。上海就有不少民众前往钱塘江观潮。”
