冥王星上的爱心

2015年2月4日,美国宇航局公布了“新地平线号”探测器最新拍摄的冥王星及其卫星图像。2006年1月19日从佛罗里达州飞向太空的探测器,历时9年终于到达冥王星。图像上赫然出现一个心形,其实是气体凝固后的冰层覆盖的区域。

During a news briefing at the Johns Hopkins Applied Physics Laboratory on Tuesday, NASA scientists revealed what they've gleaned from the latest photos of Pluto. The New Horizons spacecraft was set to make its closest approach of the dwarf planet on Tuesday, and while scientists wait for confirmation of that flyby -- and the 16 months worth of data that it will bring。周二,约翰霍普金斯应用物理实验室举行的发布会上,美国国家航空航天局(NASA)的科学家透露,他们已收集到来自冥王星的最新图像。按计划设定,新视野号飞行探测器会在周二近距离飞掠这颗矮行星,届时将向在地面等待确认飞掠的科学家传回历史16个月所收集到的数据。

根据图像,科学家还认为冥王星有活跃的地质活动,但这不代表它就是颗行星。2006年8月24日国际天文学联合会大会上,冥王星被投票确定为太阳系的“矮行星”,从而也被踢出了九大行星的圈子。当然,这一决议引来了不少争议。

Remember Pluto's heart?还记得冥王星的心吗?

除了Sputnik Planum,本篇单词没有太难的,但就是得记得,行星首字母要大写,地球(Earth)也不例外。

Well, it's broken。好吧,它的心已碎。

没听清楚的句子:And then the New Horizon spacecraft take 9 years to get there.

What you're looking at is an image of Pluto with heavily exaggerated

Sputnik Planum: 斯帕尼克平原(冥王星上的心形区域)
nitrogen: 氮
methane: 甲烷
carbon monoxide: 一氧化碳

color data -- like when you amp up the saturation on an Instagram. It's a bit hard to see (sorry) but one side of the "heart" is much bluer than the other. In fact, the left-hand side seems pretty beige-y。你所看到的冥王星图像,附带有极度夸张的色彩数据,就像你在Instagram(一款图片分享应用)上放大图片的色彩饱和度那样。图片让人看起来(抱歉~)有点儿费力,但你还是能看到这颗“心”的一边要比另一边蓝的多。实际上看,左边的部分看起来更偏于米黄色。


This seems to confirm something that the NASA scientists suspected based on recent photos of the "heart" feature: It's actually two features. In the latest images, it looks like the left half of the heart is smoother than the right, the team said at the briefing. It's possible that some texture has been lost in the compression of the image, but it could also mean that one side of the heart is a different geological feature than the other -- they're just both very bright, compared with the rest of the surface。这似乎证实了NASA科学家们基于这颗“心”的近照所作出的猜测,即实际上心有两部分组成。科研团队在简报会上指出,根据最新的图像,似乎这颗“心”的左半边要比右半边平滑的多。很有可能是在图像的压缩过程中丢失了某些质地,但这也有可能意味着,这颗“心”的一边与另一边地质特征存在差异。这两部分都很明亮,相对于冥王星表面的其他部分而言。

And speaking of Pluto's features, NASA scientists are now giving unofficial names to some of the things they've spotted -- names they can submit to the International Astronomical Union for official approval. They're sticking with the trend of underworld creatures and gods -- Pluto, after all, was the Roman god of the underworld -- and have tentatively named a previously observed dark, whale-shaped splotch (just to the left of the broken heart) after "Cthulhu," the dark deity invented by author H.P. Lovecraft。谈到冥王星的特征,NASA科学家们正准备给一些他们发现到的东西进行非正式命名。他们可以将这些名字递交给国际天文学联合会以获得官方认证。此次命名将延续以往的传统,以阴间神灵命名。毕竟,冥王星就是以罗马神话中掌管阴间的冥王所命名的。科学家们已打算将前不久观察到的一块鲸鱼形深色暗斑区域(就在这颗破碎的“心”的左边),命名为“克苏鲁”(由作家H.P。洛夫卡拉夫特创作的一个邪神)。

文本:(参照源网页的文字、根据实际录音内容修改而成):

Y: We finally make it to Pluto, Don.

D: That's right, Yaya. And then  the New Horizon spacecraft take nine years to get there.

必威游戏网址,Y: Pluto is over 4.5 billion miles from Earth. Even with a speed of 39,000 miles per hour, it still takes a long time to travel that far. But it was worth the long wait.

D: I bet scientists were surprised to find Pluto has a heart.

Y: What looks like a heart-shaped area in Pluto’s Sputnik Planum region is really ice. The area measures about a thousand miles across. That's the size of Texas. And it’s not water ice. It’s made up of nitrogen, methane and carbon monoxide. The carbon monoxide is thickest in the whiter areas of the heart.

D: Those are common gases here on Earth. Are you telling me they are solids and not gases on Pluto?

Y: Yes, Don. Being so very far from the sun, Pluto is a super cold place. The gases remain frozen, but not permanent. High resolution photos suggest that Pluto’s ice may have moved recently, like glaciers here on Earth. That means there has been some geological activity, at least within the last 100 million years. The ice also has dark streaks that are a few miles long. These are aligned in the same direction and may have been produced by winds blowing across the surface.

D: Winds?

Y: Pluto also has an atmosphere that extends about 80 miles above the surface.

D: So, Pluto isn’t just a dead rock like our moon.

Y: No. It appears to be geologically active.

D: Like a planet?

Y: Oh no, Don. We are not starting the "Pluto is a planet" argument again.
