自然科学：超级月亮和月全食同时出现

　　转眼间，中秋节又要到来，今年的中秋节更有一个好现象，超级月亮和月全食同时出现。

　　Look up next Sunday to see a truly special cosmic event: A supermoon total lunar eclipse.

　　下周日(9月27日)我们将见证一个特殊的天文现象：超级月亮和月全食同时出现。

　　Not only will the moon be at its closest point point to Earth in it orbit on Sept. 27, it will also pass completely into Earth's shadow, turning the lunar body into a red-tinted "blood moon" for anyone who has clear, dark skies on the planet's surface.

　　9月27日，月球将距离地球最近，也会完全进入地球的阴影，把月亮染成一个“血月”。届时只要有黑暗无遮挡的天空，全世界的人都能看到这一奇景。

　　"All of South America and most of North and Central America will see the entire eclipse, while those west of roughly 120°W will see it in progress at moonrise," NASA said in a statement. "You won’t need special equipment to see it. Just go outside and look up!"

　　“所有南美洲地区，以及大部分北美和美洲中部地区将能看到月全食的整个过程，而在西经120°以西地区的人们可以在月亮上升的时候观察到。”NASA(美国国家航空航天局)在一次声明中表示。“你不需要任何特殊的设备，走到外面抬头看就可以。”

　　(注：虽然我国公众在中秋佳节看不到“红月亮”和月全食，但“超级月亮”将于9月28日出现)

　　This will mark the first time a total lunar eclipse during a supermoon has occurred since 1982, and it won't happen again until 2033.

　　上一次超级月亮和月全食同时出现是在1982年，而下一次将出现在2033年。

　　During a supermoon, the moon can actually look up to 14% larger in diameter; however, everyday skywatchers might not be able to tell the difference.

　　在超级月球出现的时候，月球的直径可以比平时看起来大14%。不过大众天文观察者并不一定能观察到这种区别。

　　Scientists can also collect a fair bit of data about the moon during a lunar eclipse that they wouldn't be able to get otherwise.

　　科学家在月食期间可以也得到许多平时无法获取的月球数据。

　　For example, NASA's Lunar Reconnaissance Orbiter (LRO) will be able to take measurements of the moon's surface temperature.

　　比如，NASA(美国国家航空航天局)的LRO(美国月球勘测轨道飞行器)将可以测量月球表面的温度。

　　By learning more about how the temperature of the surface of the moon changes, scientists can actually have new insights about the structure of the surface of the moon, NASA LRO deputy project scientist Noah Petro, said in a NASA video interview.

　　“通过研究月球表面温度的变化，科学家们可以对月球表面结构有更新的认识”，LRO的助理项目科学家Noah Petro在一次视频采访中说。
