但是，模型提出，由于有更多的残骸和更多的撞击，红外线图像会展示出一个很久之前的更明亮的柯伊伯。
Long ago, though, infrared images would have showed a brighter Kuiper, due to the presence of more debris-and more collisions-the model suggests.
对于柯伊伯带探索的动机可能部分来自与人们终于认识到，我们对太阳系边缘这片寒冷黑暗的区域实在知之甚少。
Part of the motivation for exploring the Kuiper Belt was the recognition of just how little we know about this cold, dark region at the fringe of our solar system.

A new survey of the Kuiper belt - the distant area of the solar system beyond the orbit of Neptune - has turned up three new icy worlds that may be dwarf planets like Pluto.
在宽广且模糊的柯伊伯带中，微粒彼此碰撞的几率不大，因此它们会慢慢被海王星的引力共振所俘获，时间非常漫长。
In today's wide, fuzzy Kuiper belt, the particles don't meet very often, so they stick around long enough to fall into resonances with Neptune.
但天文学家们不必等那久来证实他们对太阳系外层的理解。斯卡德和他的团队已经掌握了其它柯伊伯带星体的掩星。
Astronomers won't have to wait that long to firm up their understanding of the outer solar system, though: Sicardy and his team already have occultations in hand from other Kuiper Belt objects.
柯伊伯带天体上的人工照明之所以会显得特别突出是因为不管它转向或者转离太阳，其所反射的太阳光都不会变化很大。
Artificial illumination on a Kuiper Belt Object would stand out because it would vary less than reflected sunlight does when the world moved toward or away from the sun.
科学家估计柯伊伯带很有可能存在有几万个大小超过60英里(100公里)的冰矮天体，还有数量在万亿以上的彗星。
Scientists estimate the Kuiper belt is likely home to hundreds of thousands of icy bodies larger than 60 miles (100 km) wide, as well as an estimated trillion or more comets.
哈雷彗星大约每75年会再现一次，哈雷彗星是一个“短期”的彗星，来自太阳系一个名为柯伊伯带的与众不同的部位。
