It actually happens on both solstices, that the sanke is lighten up because of the shadow that falls around it.

這個(gè)現(xiàn)象只發(fā)生在春秋分，日出日落時(shí)，建筑的拐角在金字塔北面的階梯上投下羽蛇狀的陰影。

那加火球：每年十月從湄公河里飛起來(lái)的火球

What would you do if you were walking along a tropical river at night and it suddenly began burping up egg-sized balls of red light? It happens every year in October along the Mekong river.

想象你夜晚在河邊散步，突然看到從水里升起來(lái)一個(gè)個(gè)雞蛋大的火球你會(huì)有什么反應(yīng)?每年十月湄公河就會(huì)出現(xiàn)這種神奇的現(xiàn)象。

The AVIAN HARAKIRI of Jatinga, India.

印度杰廷嘉群鳥(niǎo)自殺現(xiàn)象

This is a phenomenon that occurs at Jatinga between September and November each year. During these late monsoon months, several migratory and local birds commit mass suicide at the village. Just after sunset, between 7 and 10 pm, hundreds of birds descend from the sky, plummeting to their deaths by crashing into buildings and trees. Since birds aren’t known to be suicidal, the phenomenon has baffled villagers, visitors and scientists alike. For many years, locals believed that evil spirits living in the skies were responsible for bringing down the birds .

每年九到十一月份之間，只要到了季風(fēng)時(shí)節(jié)晚期，都會(huì)有鳥(niǎo)群在杰廷嘉“集體自殺”，包括當(dāng)?shù)氐镍B(niǎo)類以及其他候鳥(niǎo)。在日落后的19點(diǎn)至22點(diǎn)之前，數(shù)以百計(jì)的鳥(niǎo)兒會(huì)從空中飛下來(lái)，撞到墻上或樹(shù)上死亡。鳥(niǎo)類不是具有自殺性的物種，所以這一現(xiàn)象讓村民、游客、科學(xué)家們都感到費(fèi)解。多年以來(lái)，這里的村民都認(rèn)為是空中有邪惡幽靈存在，才導(dǎo)致群鳥(niǎo)自殺。

Ornithologists have made many credible theories but the mystery is till yet to be explained properly.

鳥(niǎo)類學(xué)家提出了很多猜想，但至今仍唯有合理的解釋。

Manhattanhenge

曼哈頓

It is an event during which the setting sun is aligned with the east–west streets of the main street grid of Manhattan, New York City.

落日直直的從曼哈頓東西大道的盡頭沉下，像被鑲嵌在兩旁高聳的大樓之間。

嚴(yán)格說(shuō)來(lái)時(shí)一年兩回，夏至的日出和日落。

Check out this street in Bonn, Germany. Someone who sees it in autumn would probably think it's just another normal street. However, to appreciate its true marvel, you have to visit this place in Bonn during a particular span of 20 days in the spring.
德國(guó)波恩的這條小徑。若你秋天來(lái)看它，它并沒(méi)有什么稀奇之處，但是你要是在春天的特定那二十天到這個(gè)地方，你會(huì)覺(jué)得恍若置身仙境。

For around two-three weeks every year, this street in Bonn, Germany, becomes a popular attraction for tourists as it magically transforms into a spectacular view where cherry blossoms cover up the entire street making a tunnel, giving the street a heavenly appearance. Have a look.

大概每年春天的兩到三周，無(wú)數(shù)櫻花開(kāi)滿枝頭，搭成了一條花的走廊。
