Sky Watchers Prepare For the 'Super Bowl' of Moons
This is What's Trending Today.
The moon is providing a rare triple treat this week.
On Wednesday, much of the world will get to see not only a blue moon and a "supermoon," but also a total lunar eclipse.
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.
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.
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.
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.
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!
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.
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."
Some people are calling this week's lunar event a "super blue blood moon."
Noah Petro is a scientist with the American space agency NASA. He is calling the lunar event, "the Super Bowl of moons."
No matter the name, it is likely to impress if the skies are clear.
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.
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.
And that's What's Trending Today.

4.blood moon 血月
The Moon will appear orange or red, the result of sunlight scattering off our atmosphere, hence the name Blood Moon.

He's been out of luck this year.
We missed our train, and was out of luck in getting to work on time.

三种现象同时出现的概率非常小 。天文学家表示，自1982年以来，从未发生过如此奇观 。下一次出现要等到2037年 。
当地球运行至太阳和满月之间时会发生月全食 。地球遮住了太阳光线，月亮黯然失色 。
周三凌晨月亮落下前，美国和加拿大的西半部很容易能观赏到这次月食 。待周三晚间至周四凌晨，整个太平洋地区和东亚地区也能看到此次月食 。
然而，美国东海岸地区就没这么走运了 。月食才刚刚开始，月亮就要落下了 。而欧洲、非洲大部分地区及南美洲也将无缘这次月食 。
“蓝月亮”是指一个月内的第二次满月 。这类现象极其罕见，因此，说英语的人常用“千载难逢（once in a blue moon）”形容少见的事情 。
“超级月亮”是指满月或新月 。因月亮比往常更靠近地球，所以看起来也比平常更大更亮 。
在月全食过程中，地球的阴影遮住了月亮表面，导致其呈现红色 。因此，它也被称为“血月” 。
诺亚·佩特罗（Noah Petro）是美国宇航局的科学家 。他称这次月球事件为“月亮超级碗” 。
当太阳、地球和月球完美地并排形成月食时，科学家们将在夏威夷利用望远镜进行观测 。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 。
正如去年8月的日全食让地球表面降温，月全食也会让月亮表面降温 。研究人员将进一步分析这种突如其来的降温——从太阳照射的温度至几近严寒 。
