CNN News: 蓝色月亮

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.
 
快速问答：平均一年有多少次满月?11 12 10或14。在大多数年份里，每个月有12次满月。
 
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月将会有13次满月，其中两次是满月，如果一个月有两次满月，就会出现所谓的“蓝月亮”。
 
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.
 
但蓝月亮只是我们今年13个命名的月亮之一，其他的还包括“蠕虫月亮”、“巴克月亮”、“鲟鱼月亮”。根据农民年鉴，印第安人给它们起这些名字是为了记录季节。1月份的“狼月”可能是因为人们在1月份听到了狼群的嚎叫。三月的“虫月”得名于温暖的地面上出现蚯蚓的迹象。除了这种“观月”之外，今年夏天还有一对半影月食。
 
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.
 
当太阳、地球和月球在太空中排成一条直线，地球正好在中间时，月食就发生了。太阳照射在地球上，地球投下阴影，当月球更深地进入阴影时，它看起来会变成暗红色。为什么是红色呢?因为大气层过滤了蓝光。有些人把这种现象称为“血月”。美国国家航空航天局表示，月食通常每年至少发生两次，但并不是所有月食都是完整的。实际上有三种不同的类型。
 
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过地球外围的阴影时所形成的现象。美国宇航局说，这是如此微妙，你甚至可能没有注意到。日偏食是月亮投进地球的一部分阴影，但不是全部，所以只有一部分月亮变暗。月全食是最好的，这时整个月亮都在地球的阴影里，变成了深红色。记住，你不需要望远镜或任何特殊设备来观察月食，但需要用双筒望远镜或望远镜就可以啦。不管怎样，只要走到外面，找到月亮，好好享受。
