Some mechanism is renewing Charon's surface, and cryovolcanism is the most probable of the possible mechanisms, write Jason Cook, Steven Desch, Ted Roush, Chad Trujillo, and Tom Geballe in a paper they published this week in The Astrophysical Journal.

Jason Cook， Steven Desch， Ted Roush， Chad Trujillo， and Tom Geballe 在《天体物理学期刊》的一篇论文中写道："某些机制在更新喀戎的表面，火山作用是最有可能的机制。"

Rutledge said there are no widely accepted alternate theories for objects bright in X-rays and faint in visible light like Calvera.

拉特利奇指出，象"卡尔维拉"这样的天体，具有强烈的X射线，同时可见光却很暗淡，对此并没有一个公认的理论可以解释。

Astrophysicist Sara Seager of MIT, who was not involved in the latest discovery, said while the possibility is exciting, another more convincing image of the object is in order.

麻省理工学院的天体物理学家萨拉·西格没有参与这项最新发现，但她说：存在行星的可能性令人兴奋，同时已经准备好为该物体再拍摄一张更加令人信服的图片。

The Harvard Smithsonian Center for Astrophysics astronomers studied two dusty regions of star formation in the constellation Serpens Cauda, located 15,000 light years away.

哈佛大学史密森天体物理中心的天文学家们研究了位于15000光年之外巨蛇座尾部的两个富含星际尘埃的恒星形成区域。

Arrayed along the solar system's ecliptic plane, the three celestial beacons forming this skyscape's eye-catching line-up with the Moon are Saturn, then Mars, and finally Regulus, alpha star of the constellation Leo.

沿着太阳系的黄道盘面排列，这三个天体形成了这张影像中引人注目的风景，与月球排列在一起的是土星，然后是火星，最后是轩辕十四－狮子座α星。

The Chandra image shows hot gas in the Sombrero galaxy and point sources that are a mixture of galaxy members and background objects.

钱德拉的图象揭示出草帽星系中的热气体，以及由星系成员星和背景天体组成的点源。

An autonomous optical navigation scheme for cruise phase is presented in this paper, in which the relative position for probes is based on the star light and body edge data that is measured by star sensor and optical navigation camera respectively.

提出了一种用于探测器在巡航段的自主光学导航方案，该方案利用光学导航相机以及星敏感器，通过测量星光信息以及天体边缘的信息，得出了探测器的相对位置。

Earth Tides is a subject which holds a key position in relation to geophysics, geodesy and astronomy, since it is a phenomenon which consists of an elastic-viscous deformation of the terrestrial globe, and this is caused by the gravitational action of the Moon, the Sun, and other Heavenly Bodies.

固体潮是固体地球在太阳和月亮等天体引潮力的作用下所产生的一种粘弹性形变现象，因而是一门连接地球物理学、大地测量学和天文学的学科。

The gravitation between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them.

两个天体之间的引力与它们的质量成正比，而与它们之间距离的平方成反比。

Alister Ling published a list of 60 "planetary nebulae visible from the city" in the now-defunct Deep Sky magazine (Summer 1986 issue).

在1986年夏天出版的《深空天体杂志》上阿里斯特·林公布了一张60个的&城市中可见的行星状星云&表。

The split between the two groups can hardly be papered over.
