Sky Watchers: Look Out for ‘Supermoon’
It is coming very soon. You can hear about it in a song performed by American singer Victoria Vox.
"Oooo, I'm waiting on a supermoon to come into view, on the horizon..."
Sky watchers will have a special treat Monday night. That is when a supermoon appears in the night sky.
So what is a supermoon?
It is a full moon that appears bigger and brighter than normal. The American space agency, NASA, says the full moon on Monday will be the closest full moon of the year. In fact, the moon has not been this close to Earth since 1948.
The moon's orbit around Earth is slightly elliptical – it does not move in an even circle. That means it sometimes moves closer to our planet. But other times it is farther away.
A supermoon is when the moon and Earth are closer than they usually are, if only by a small amount. But even that small distance can make the moon appear up to 14 percent larger and 30 percent brighter than a normal full moon.
Even if the skies are cloudy where you are on November 14th, the moon will still be very bright this weekend. The best time to see it is just before sunrise.
"I've been telling people to go out at night on either Sunday or Monday night to see the supermoon," said Noah Petro, who works for NASA's Lunar Reconnaissance Orbiter mission. He said that the difference between Sunday night and Monday night will be very small, so either night will be good.
"Anytime after sunset should be fine" to see the moon, he said. "You don't have to stay up all night to see it, unless you really want to!"
The name supermoon is fairly new. It was the idea of astrologer Richard Nolle in 1979.
In the past, some people called a supermoon, a "mega beaver moon." That name comes from a best-selling book, the Old Farmer's Almanac. It said the name was first used before the creation of the United States. It said that "for both the colonists and the Algonquin tribes, this was the time to set beaver traps before the swamps froze, to ensure a supply of warm winter furs."
This will be is the second of three supermoons in recent months. If you miss this one, the next chance is on December 14.
The bad news about next month's supermoon is that its brightness will limit what we can see of another light show in the night sky -- the Geminid meteor shower. That is when as many as 100 or more shooting stars move fast across the night sky every hour.
The moon, however, will not be this close again until November 25, 2034.
But for now you can enjoy more of Victoria Vox's song, Supermoon.

come into view 看得见；进入视野
The village will come into view at the next turn.
A green orchard will come into view as visitors enter the pavilion.

I used to stay up late with my mom and watch movies.
I couldn't stay up any longer, so I went to bed.
超级月亮即将现身 。你可以从美国歌手维多利亚·沃克斯（ Victoria Vox）的歌声中听到 。
周一晚间，天文爱好者能够欣赏到一场特殊的视觉盛宴 。届时，超级月亮将现身夜空 。
超级月亮是指比平时更大更亮的满月 。美国宇航局NASA表示，周一的满月将是本年月亮距地球距离最近的一次 。其实，上一次月亮距地球如此之近是在1948年 。
月亮绕地球运行轨道为椭圆形而非正圆 。也就是说，有时月亮会离地球近一些 。而有的时候离地球远一些 。
当超级月亮出现时，地球与月亮的间距比往常更近，虽然距离变化不是太大 。但即便是微小的差距，月亮也会比平时看起来大14%，而亮度也会提高30% 。
即使11月14日天气多云，也不会影响周末月亮的亮度 。最佳赏月时间为日出之前 。
“我一直提醒大家，周日或周一晚间出门观赏超级月亮，”诺亚·佩德罗说道，他是NASA月球侦察轨道飞行器任务的工作人员 。他说，周日和周一晚间都是最佳观赏时间，月亮几乎没什么变化 。
超级月亮这一称呼是近代才出现的 。1979年，由占星家理查德·诺勒（Richard Nolle）提出 。
过去，有的人称超级月亮为“大型海狸月亮” 。该称呼取自一本畅销书《老农历》 。据说，这一称呼刚出现时，美国还没有成立 。据说“此时，殖民者和阿尔冈琴部落都会趁沼泽结冰前，设陷阱捕捉海狸，以保证有足够的海狸皮过冬” 。
最近几个月将出现三次超级月亮，这是第二次 。如果错过了本次的超级月亮，你还有机会在12月14日欣赏一次 。
下月的超级月亮伴随着一个坏消息，届时月亮的亮度会影响夜空中另一场光影秀——双子座流星雨 。到那时，每小时会有100多颗流星划过夜空 。
