8楼的坑当天完成


最新的一张由新视野号拍摄的冥王星图片,揭示了冥王星表面令人蛋疼的地貌。这片地域的边界十分的奇葩混乱。众多科学家表示他们的脑袋已经晕了。

新视野号计划的发起者,计划负责人,西南大学的Alan Stern说:“冥王星正在席卷我们对太阳系的认知,如果有个画家在飞掠之前画一幅冥王星的想象图。我会说他的思想太‘前卫’,但是现在我不得不说,那是没人能预料到的,他画的也许就是真实的景象。”

新视野号的图片数据下载工作从美国的“资本主义劳动节”就开始了,现在我们已经有相当的数据用于描绘出冥王星的表面。这些图像中最好的分辨率达到了每像素400米。我们从这些图像看到了多样性的地质,氮雪从山间飘向冰冻的平原,还有被冥王星表面的飘飞物质所覆盖的谷地。这片庞大而又寒冷的区域可以使我们联想到万里之外的木卫二—木星的冰冻卫星。

Jeff Moore新视野号地质观测小组负责人说:“这片地貌几乎和火星一样复杂。这片拥有散落的山峰,巨大的水冰与氮冰组成的区域被非正式的称为‘斯普尼克特平原’。”

新图像首次展现了那个大大的环形山。这些极度年轻的环形山坐落在已知最古老的地块上。这片地区还有可能出现棕黑色的风来塑造那些棕黑色的丘,谁知道那是沙丘还是什么丘。

周五将会有更多的有关冥王星的小卫星的图片被公开在新视野号官网上。

还有,为何新视野号可以观测到暮光中的地形呢?这些惊喜全部源于冥王星大气中的雾霾,这些雾霾散射了少量的阳光到冥王星的背面,使得科学家可以研究阴暗面的地形。


英文原文:

New close-up images ofPluto from NASA’s New Horizons spacecraft reveal a bewildering variety ofsurface features that have scientists reeling because of their range andcomplexity.
“Pluto is showing us a diversity of landforms and complexity ofprocesses that rival anything we’ve seen in the solar system,” said NewHorizons Principal Investigator Alan Stern, of the Southwest Research Institute(SwRI), Boulder, Colorado. “If an artist had painted this Pluto before ourflyby, I probably would have called it over the top — but that’s what isactually there.”
New Horizons began its yearlong download of new images and otherdata over the Labor Day weekend. Images downlinked in the past few days havemore than doubled the amount of Pluto’s surface seen at resolutions as good as400 meters (440 yards) per pixel. They reveal new features as diverse aspossible dunes, nitrogen ice flows that apparently oozed out of mountainousregions onto plains, and even networks of valleys that may have been carved bymaterial flowing over Pluto’s surface. They also show large regions thatdisplay chaotically jumbled mountains reminiscent of disrupted terrains onJupiter’s icy moon Europa.

“The surface of Pluto is every bit as complex as that of Mars,” said JeffMoore, leader of the New Horizons Geology, Geophysics and Imaging (GGI) team atNASA’s Ames Research Center in Moffett Field, California. “The randomly jumbledmountains might be huge blocks of hard water ice floating within a vast,denser, softer deposit of frozen nitrogen within the region informally namedSputnik Planum.”
New images also show the most heavily cratered -- and thus oldest-- terrain yet seen by New Horizons on Pluto next to the youngest, mostcrater-free icy plains. There might even be a field of dark wind-blown dunes,among other possibilities.
“Seeing dunes on Pluto -- if that is what they are -- would becompletely wild, because Pluto’s atmosphere today is so thin,” said William B.McKinnon, a GGI deputy lead from Washington University, St. Louis. “EitherPluto had a thicker atmosphere in the past, or some process we haven’t figuredout is at work. It’s a head-scratcher.”
Discoveries being made from the new imagery are not limited toPluto’s surface. Better images of Pluto’s moons Charon, Nix, and Hydra will bereleased Friday at the rawimages site for New Horizons’ Long Range Reconnaissance Imager (LORRI),revealing that each moon is unique and that big moon Charon’s geological pastwas a tortured one.

现在新视野号还没有数据解码和公布,所以我下午回家之后会将两个小卫星的图搬出。由于太小,分辨率不高,所以大家先凑合着

新图回归,有关冥王星表面的新细节

请大家等待半天或几小时,楼主正在翻译所有的图片以及NASA的文章

最新的有关冥王星的图片已从新视野号回归。这些图像表现了冥王星表面华丽以及让众多科学家大吃一惊的细节。这片固态氮的平原被分层的雾霾笼罩着。这片地貌对我们来说陌生而又如同艺术家的作品一样精美。
这些照片由RALPH广角相机以及多谱线相机MVIC拍摄于7月14日。并在9月13传回地球。这幅照片的视角是朝向斯普尼克特平原。由于冥王星特殊的相位,是我们可以清楚的看到大气层的部分细节以及冥王星地表的地形。这片照片展现了约为1250千米宽的地区。
“这幅图片如此精彩,以至于让你感受到身临其境。看起来就像是你自己在探索者这颗星球的表面。”冥王星任务的发起者Alan Stern说“这图里的信息信息量很大,它展现的又关这颗星球的诸多细节,有关于大气,地貌,冰川以及平原。”
这片杰出的背光照拥有着极高的分辨率,这幅多频段光谱摄影也表现的冥王星富氮大气的诸多细节,尤其是那些分层的雾霾。这些雾霾在距离冥王星表面上空100公里的地方漂浮着。冥王星的地表遍布着那些薄雾,绵延千里,笼罩在冥王星傍晚的地表上。有些已入夜的薄雾被霞光照亮,在崎岖的山间徘徊,游荡,吹拂着那些山崖。
Will Grundy新视野号的某个研究小组组长说:“这种薄雾就如同地球上的天气,他们每天都是不同的。”
结合之前的的图片表明,冥王星上也有类似于地球水循环的体系。但是冥王星的某种物质的循环包括的一些其他物质,可能是氮循环或者是水冰什么的。
明亮的东部平原—斯普尼克特平原的东边,可能被覆盖的一些类似于冰的物质。RALPH的图片表明,有种冰川运动将这些物质带回斯普尼克特平原。这个地形十分类似于地球的格林兰岛或者是南极洲。
“我们没有指望在冥王星上发现水循环,因为那里太冷了。”Alan Howard 说“那里的微弱阳关无法推动整个水循环…..因为水循环需要液态水的存在。”

The latest images from NASA’s New Horizons spacecraft have scientists stunned – not only for their breathtaking views of Pluto’s majestic icy mountains, streams of frozen nitrogen and haunting low-lying hazes, but also for their strangely familiar, arctic look.
This new view of Pluto’s crescent – taken by New Horizons’ wide-angle Ralph/Multispectral Visual Imaging Camera (MVIC) on July 14 and downlinked to Earth on Sept. 13 – offers an oblique look across Plutonian landscapes with dramatic backlighting from the sun. It spectacularly highlights Pluto’s varied terrains and extended atmosphere. The scene measures 780 miles (1,250 kilometers) across.
“This image really makes you feel you are there, at Pluto, surveying the landscape for yourself,” said New Horizons Principal Investigator Alan Stern, of the Southwest Research Institute, Boulder, Colorado. “But this image is also a scientific bonanza, revealing new details about Pluto’s atmosphere, mountains, glaciers and plains.”
Owing to its favorable backlighting and high resolution, this MVIC image also reveals new details of hazes throughout Pluto’s tenuous but extended nitrogen atmosphere. The image shows more than a dozen thin haze layers extending from near the ground to at least 60 miles (100 kilometers) above the surface. In addition, the image reveals at least one bank of fog-like, low-lying haze illuminated by the setting sun against Pluto’s dark side, raked by shadows from nearby mountains.
“In addition to being visually stunning, these low-lying hazes hint at the weather changing from day to day on Pluto, just like it does here on Earth,” said Will Grundy, lead of the New Horizons Composition team from Lowell Observatory, Flagstaff, Arizona.
Combined with other recently downloaded pictures, this new image also provides evidence for a remarkably Earth-like “hydrological” cycle on Pluto – but involving soft and exotic ices, including nitrogen, rather than water ice.
Bright areas east of the vast icy plain informally named Sputnik Planum appear to have been blanketed by these ices, which may have evaporated from the surface of Sputnik and then been redeposited to the east. The new Ralph imager panorama also reveals glaciers flowing back into Sputnik Planum from this blanketed region; these features are similar to the frozen streams on the margins of ice caps on Greenland and Antarctica.
“We did not expect to find hints of a nitrogen-based glacial cycle on Pluto operating in the frigid conditions of the outer solar system,” said Alan Howard, a member of the mission’s Geology, Geophysics and Imaging team from the University of Virginia, Charlottesville. “Driven by dim sunlight, this would be directly comparable to the hydrological cycle that feeds ice caps on Earth, where water is evaporated from the oceans, falls as snow, and returns to the seas through glacial flow.”

这片带着阴影的壮丽山脉和冰原之原野,绵延向这颗遥远行星的地平线伸展。影像摄于7月14日当新地平线号通过最近点后的15分钟,回首眺望冥王星时的距离为18,000公里。这幅精采、低角度的暮光景象,呈现了前景左侧称为Norgay Montes的崎岖山脉、地平线附近的HillaryMontes、及右侧平滑的史泼尼克平原。而在这幅背光的影像里,亦可见到冥王星稀薄大气的分层。这片奇特但看来熟悉的冻原,可能有氮冰和干冰,以及高耸约3,500公尺、和地球壮丽山峰几乎等高的水冰峰。这片冥王星地貌的跨幅为380公里。

这些就是冥王星上的类冰川结构了,红色箭头指向冰川主体,蓝色箭头的区域则为类似冲积扇的结构。
