CNN News: 藍色月亮

AZUZ: 10 Second Trivia. On average, how many full moons are there in a year? 11, 12, 10 or 14. In most years there are 12 full moons one occurring per month.
 
快速問答：平均一年有多少次滿月?11 12 10或14。在大多數(shù)年份里，每個月有12次滿月。
 
But this year there will be 13 with two full moons in October and when you have two full moons in one month, you have what's said to be a "blue moon".
 
但是今年10月將會有13次滿月，其中兩次是滿月，如果一個月有兩次滿月，就會出現(xiàn)所謂的“藍月亮”。
 
But blue is just one of the 13 named moons we'll have this year, the others include the "worm moon", "buck moon", "sturgeon moon". According to the Farmer's Almanac, Native Americans gave them these names to keep track of the seasons. January's "wolf moon" is likely because wolf packs were heard howling in January. March's "worm moon" is named for signs of earthworms appearing in the warmer ground. To add to this "moon gazing", there's a pair of penumbral lunar eclipses coming this summer.
 
但藍月亮只是我們今年13個命名的月亮之一，其他的還包括“蠕蟲月亮”、“巴克月亮”、“鱘魚月亮”。根據(jù)農(nóng)民年鑒，印第安人給它們起這些名字是為了記錄季節(jié)。1月份的“狼月”可能是因為人們在1月份聽到了狼群的嚎叫。三月的“蟲月”得名于溫暖的地面上出現(xiàn)蚯蚓的跡象。除了這種“觀月”之外，今年夏天還有一對半影月食。
 
UNIDENTIFIED FEMALE: A lunar eclipse happens when the sun, the Earth and the moon line up in a straight line in space with the Earth smack in the middle. The sun shines light on the Earth which casts a shadow and as the moon moves deeper into that shadow, it appears to turn a dark reddish color. Why red? Because the atmosphere is filtering out the blue light. Some people have nicknamed this effect "the blood moon". NASA says that lunar eclipses typically happen at least twice a year but not all of them are total. There are actually three different types.
 
當(dāng)太陽、地球和月球在太空中排成一條直線，地球正好在中間時，月食就發(fā)生了。太陽照射在地球上，地球投下陰影，當(dāng)月球更深地進入陰影時，它看起來會變成暗紅色。為什么是紅色呢?因為大氣層過濾了藍光。有些人把這種現(xiàn)象稱為“血月”。美國國家航空航天局表示，月食通常每年至少發(fā)生兩次，但并不是所有月食都是完整的。實際上有三種不同的類型。
 
A penumbral eclipse is when the moon passes through the outskirts of the Earth's shadow. NASA says this is so subtle, you might not even notice. A partial eclipse is when the moon dips into part of the Earth's shadow but not all of it so only a portion of the moon turns dark. A total eclipse is the best and that's when the entire moon is in the Earth's shadow turning it that deep red color. Remember you don't need a telescope or any special equipment to view a lunar eclipse but having binoculars or a telescope might make it more fun. Either way, just go outside, find the moon and enjoy.
 
半影月食是指月球穿過地球外圍的陰影時所形成的現(xiàn)象。美國宇航局說，這是如此微妙，你甚至可能沒有注意到。日偏食是月亮投進地球的一部分陰影，但不是全部，所以只有一部分月亮變暗。月全食是最好的，這時整個月亮都在地球的陰影里，變成了深紅色。記住，你不需要望遠鏡或任何特殊設(shè)備來觀察月食，但需要用雙筒望遠鏡或望遠鏡就可以啦。不管怎樣，只要走到外面，找到月亮，好好享受。
