[翻译]木星大红斑

只看楼主收藏回复

●原文来自NASA的电子书:A Quarter-Century of Discovery with the Hubble Space Telescope(《哈勃空间望远镜:二十五年的探索发现》)中的第一章
●对于原文的部分语句,我难以翻译,所以在翻译中避开了某些内容,并用“[*]”标出,但基本不影响阅读。
●有改进意见的欢迎提出。

    Jupiter’s Great Red Spot
    The planet Jupiter is best known for its Great Red Spot, a storm big enough to swallow Earth. Hubble observations over nearly two decades show that this storm is shrinking dramatically.
    木星大红斑
    木星以大红斑——一个大得足以吞下地球的风暴著称。哈勃对其超过二十年的观测表明这个风暴正在逐渐减小。

      Located in Jupiter’s southern hemisphere, the GRS is larger than Earth, with winds inside it raging at 500 miles per hour. While its longitude drifts relative to surrounding atmospheric bands, the storm’s latitude has been stable for as long as records of it have been kept. The GRS may have been seen as early as 1632 by Leander Bandtius, Abbot of Dunisburgh. In 1664, the philosopher, architect, and polymath Robert Hooke reported observing a spot that moved from east to west on the planet. The next year, astronomer, mathematician, and engineer Giovanni Cassini was the first to note a “permanent spot.”

      位于木星南半球,大红斑比地球还大,它内部的怒风可以达到五百英里每小时。大红斑的经度由于周围大气带而变化,但它的纬度自从发现起就一直保持着稳定。大红斑早在1632年就被Dunisburgh的修道院长Leander Bandtius观察到。在1644年,哲学家,建筑师,博学的罗伯特•虎克称发现了一个在木星上从东向西移动的斑块。一年后,天文学家,数学家,工程师高万尼•卡西尼第一个将其记录为“永久的斑块”。

          The Voyager spacecraft in 1979 measured the long axis of the GRS to be 14,500 miles across; historic observations as far back as the late 1800s gauged the GRS to be 25,500 miles across. Hubble’s long life has allowed astronomers to follow Jupiter’s atmospheric activity over a period spanning nearly two decades. In a study led by Amy Simon of NASA’s Goddard Space Flight Center, Hubble observations show that the GRS is now approximately 8,000 miles from top to bottom and 10,250 miles across: the GRS has now shrunk to the smallest size ever measured, having lost half its size over the past hundred years.

          在1979年旅行者号测量其长轴约为14500英里,历史上在十九世纪后期的测量结果为25500英里。哈勃服役时间之长,让天文学家可以在超过二十年的时间里观测木星的大气活动。在一个由来自NASA的Goddard空间飞行中心的艾米•西莫领导的研究中,哈勃观测表明大红斑现在从上到下长8000英里,而从左到右宽10250英里——大红斑已经缩小到有史以来的最小尺寸——在百年间失去了一半的大小。

            In the new Hubble observations, it is apparent that very small eddies are feeding into the storm. Simon and her team hypothesize that these eddies may be responsible for the sudden change by altering the internal dynamics and energy of the GRS. They plan to study the future motions of the small eddies, along with the internal motions of the GRS, to determine whether such eddies can feed or sap momentum entering the upwelling vortex and contribute to changes in the size and shape of the Great Red Spot.

            在哈勃新的观测中,可以清晰看小漩涡进入大红斑风暴。西莫和她的团队假定这些小漩涡与大红斑的内动力和能量的改变有关[*]。他们决定研究这些小漩涡未来的运动和大红斑内部的运动,以此来确定这样的漩涡是否可以补充或消耗上升漩涡的动力,以及是否促进大红斑大小及形状的改变。
