The moon is providing a rare triple treat this week.
月亮将会在本周给人们带来一次罕见的三重乐趣。

On Wednesday, much of the world will get to see not only a blue moon and a "supermoon," but also a total lunar eclipse.
周三，世界上很多地方不仅将会看到蓝月亮和超级月亮，还会看到月全食。

Having all three events taking place at the same time is extremely unusual. Astronomers say this has not happened since 1982. And it won't happen again until 2037.
这三类事件同时发生是非常罕见的。天文学家表示，从1982年起就没有发生过这种好事，而且直到2037年才会再次发生。

A total lunar eclipse happens when the Earth comes between the Sun and a full moon. The Earth blocks the sun's light, making the moon appear dark in the sky.
当地球运行到太阳和满月之间就会发生月全食。地球遮挡了太阳的光线，使得月亮在天空中变暗。

The eclipse will be easiest to see in the western half of the United States and Canada before the moon sets early Wednesday morning. It will also be visible across the Pacific Ocean into East Asia as the moon rises Wednesday night into Thursday.
当月亮在周三凌晨落下之前，在美国和加拿大的西半部很容易就能看到这次月食。随着月球在周三晚上升起直到周四，横跨太平洋直到东亚也能看到这次月食。

The U.S. East Coast, however, is out of luck. The moon will be setting just as the eclipse gets started. Europe, most of Africa and South America also will miss out.
然而美国东海岸就不够幸运。月食正要开始时，月亮就要落下了。欧洲、非洲大部分地区以及南美洲也都将会错过这次月食。

A blue moon is a second full moon in one month. It is rare enough that English speakers use the expression "once in a blue moon" to describe something that does not happen often!
蓝月亮是指一个月内的第二次满月。这类事件极其罕见，所以英语人士用“once in a blue moon”这句短语来描述那些不经常发生的事情。

A supermoon is a full or new moon. It appears brighter and bigger than usual because the moon is closer to the earth than usual.
超级月亮是指满月或新月。由于月亮比平常更靠近地球，所以它看起来也比平常更大更亮。

In a total lunar eclipse, the Earth covers the moon's surface with its shadow, giving it a red-like color. For that reason, it is also known as a "blood moon."
在月全食中，地球的阴影遮住了月亮表面，使其呈现出红色。正因为此，它也被称之为血月。

Some people are calling this week's lunar event a "super blue blood moon."
有些人把本周的月球大事件称之为“超级蓝血月”。

Noah Petro is a scientist with the American space agency NASA. He is calling the lunar event, "the Super Bowl of moons."
诺亚·佩特罗（Noah Petro）是美国宇航局的一名科学家。他称这次月球事件为“月亮超级碗”。

No matter the name, it is likely to impress if the skies are clear.
不管怎么取名，如果天空晴朗，它可能都会给人留下深刻的印象。

As the sun lines up perfectly with the Earth and then the moon for the eclipse, scientists will make observations from a telescope in Hawaii. They are also planning to collect information from NASA's moon-circling Lunar Reconnaissance Orbiter.
当太阳和地球以及月球完美地排成一行形成月食时，科学家们将通过夏威夷的望远镜进行观测。他们还计划通过美国宇航局绕月飞行的月球轨道探测器收集信息。

Just as last August's total solar eclipse cooled the Earth's surface, a lunar eclipse cools the surface of the moon. It's this sudden cooling — from the heat of direct sunlight to almost a deep freeze — that researchers will be studying.
正如去年8月的日全食让地球表面降温，月食也会让月亮表面降温。从太阳直射的热度到几近严寒，研究人员将会对这种突如其来的降温进行研究。
