In 1802, German astronomer Heinrich Olbers observed what he thought was a planet within the Main Asteroid Belt.
1802年，德国天文学家海因里希·奥尔伯斯(Heinrich Olbers)观察到了他认为是位于主小行星带内的一颗行星。
In time, astronomers would come to name this body Pallas, an alternate name for the Greek warrior goddess Athena.
随着时间的推移，天文学家将这个身体命名为帕拉斯，希腊武士女神雅典娜的另一个名字。
The subsequent discovery of many more asteroids in the Main Belt would lead to Pallas being reclassified as a large asteroid, the third-largest in the Belt after Ceres and Vesta.
随后在主带发现更多的小行星将导致帕拉斯被重新归类为一颗大型小行星，这是该带中的第三大小行星，仅次于“谷神星”和“灶神星”。
For centuries, astronomers have sought to get a better look at Pallas to learn more about its size, shape, and composition.
几个世纪以来，天文学家一直试图更好地观察帕拉斯，以了解更多关于它的大小、形状和组成的信息。
As of the turn of the century, astronomers had come to conclude that it was an oblate spheroid (an elongated sphere).
在世纪之交，天文学家已经得出结论，它是一个扁球体(一个细长的球体)。
Thanks to a new study by an international team, the first detailed images of Pallas have finally been taken, which reveal that its shape is more akin to a "golf ball" – i.e.
多亏了一个国际团队的一项新研究，帕拉斯的第一张详细图像终于被拍摄出来了，这表明它的形状更像是一个“高尔夫球”-也就是说。
heavily dimpled.
严重的酒窝。
Pierre Vernazza of the Laboratoire d'Astrophyisque de Marseille in France was the principal investigator of the team, which included members from 21 research institutions from around the world.
法国马赛天体物理研究所的Pierre Vernazza是该团队的首席调查员，该团队包括来自世界各地21个研究机构的成员。
Michaël Marsset, a postdoctoral associate with MIT's Department of Earth, Atmospheric and Planetary Sciences, was the lead author on the study (which recently appeared in the journal Nature Astronomy).
Michaël Marsset是麻省理工学院地球、大气和行星科学系的博士后同事，他是这项研究的主要作者(最近发表在“自然天文学”杂志上)。
For centuries, astronomers have known that Pallas orbits along a highly tilted orbit compared to the majority of objects in the Main Asteroid Belt.
几个世纪以来，天文学家已经知道，与主要小行星带中的大多数天体相比，Pallas的轨道是沿着高度倾斜的轨道运行的。
Whereas most of these objects follow the same roughly elliptical path around the Sun and have orbital inclinations of less than 30°, Pallas orbit is inclined 34.837° relative to the Solar plane (for reasons that have remained a mystery).
尽管大多数这些天体都沿着同样的大致椭圆轨道绕太阳运行，轨道倾角小于30°，但帕拉斯轨道相对于太阳平面倾斜34.837°(原因至今仍是一个谜)。
For the sake of their study, Vernazza and his team obtained 11 images of Pallas that were acquired by the Spectro-Polarimetric High-contrast Exoplanet REsearch instrument (SPHERE) on the ESO's Very Large Telescope (VLT).
为了他们的研究，Vernazza和他的团队获得了11张帕拉斯的图像，这些图像是由ESO的“甚大望远镜”(VLT)上的“光谱-极化高对比度系外行星研究仪器”(球体)获得的。
