最美丽的行星--土星 土星古称镇星或填星,因为土星公转周期大约为29.5年,我国古代有28宿,土星几乎是每年在一个宿中,有镇住或填满该宿的意味,所以称为镇星或填星，直径119300公里(为地球的9.5倍)，是太阳系第二大行星。它与邻居木星十分相像，表面也是液态氢和氦的海洋，上方同样覆盖着厚厚的云层。土星上狂风肆虐，沿东西方向的风速可超过每小时1600公里。土星上空的云层就是这些狂风造成的，云层中含有大量的结晶氨。 土星:半径60268km、质量5.69*10^26kg 编辑本段￡土星(Saturn) 轨道距太阳142，940万千米，公转周期为10759.5天，相当于29.5个地球年，视星等为0.67等。在太阳系的行星中，土星的光环最惹人注目，它使土星看上去就像戴着一顶漂亮的大草帽。观测表明构成光环的物质是碎冰块、岩石块、尘埃、颗粒等，它们排列成一系列的圆圈，绕着土星旋转。 土星运动迟缓，人们便将它看做掌握时间和命运的象征。罗马神话中称之为第二代天神克洛诺斯，它是在推翻父亲之后登上天神宝座的。无论东方还是西方，都把土星与人类密切相关的农业联系在一起，在天文学中表示的符号，像是一把主宰着农业的大镰刀。 在1781年发现天王星之前，人们曾认为土星是离太阳最远的行星。在望远镜中可以看到土星被一条美丽的光环围绕。土星还有较多的卫星，到1978年为止，已发现并证实的有10个，以后又陆续有人提出新的发现。 土星在很多方面像木星，如它与木星同属于巨行星，它的体积是地球的745倍，质量是地球的95.18倍。在太阳系八大行星中，土星的大小和质量仅次于木星，占第二位。它像木星一样被色彩斑斓的云带所缭绕，并被较多的卫星所拱卫。它由于快速自转而呈扁球形。赤道半径约为60，000公里。土星的平均密度只有0.70克/厘米立方米，是八大行星中密度最小的。如果把它放在水中，它会浮在水面上。土星的大半径和低密度使其表面的重力加速度和地球表面相近。土星在冲日时的亮度可与天空中最亮的恒星相比。由于光环的平面与土星轨道面不重合，而且光环平面在绕日运动中方向保持不变，所以从地球上看，光环的视面积便不固定，从而使土星的视亮度也发生变化。当土星光环有最大视面积时，土星显得亮一些;当视线正好与光环平面重合时，光环便呈现为一条直线，土星就显得暗些。二者之间的亮度大约相差3倍。 土星绕太阳公转的轨道半径约为14亿公里，它的轨道是椭圆的。它同太阳的距离在近日点时和在远日点时相差约1 .5亿公里。土星绕太阳公转的平均速度约为每秒9.64公里，公转一周约29.5年。土星也有四季，只是每一季的时间要长达7年多，因为离太阳遥远，即使是夏季也十极其寒冷。土星自转很快，但不同纬度自转的速度却不一样，这种差别比木星还大。赤道上自转周期是10小时14分，纬度60度处则变成10小时40分。这就是说在土星赤道上，一个昼夜只有10小时零14分。 土星大气以氢、氦为主，并含有甲烷和其他气体，大气中飘浮着由稠密的氨晶体组成的云。从望远镜中看去，这些云像木星的云一样形成相互平行的条纹，但不如木星云带那样鲜艳，只是比木星云带规则得多。土星云带以金黄色为主，其余是橘黄色、淡黄色等。土星的表面同木星一样，也是流体的。它赤道附近的气流与自转方向相同，速度可达每秒500米，比木星上的风力要大得多。 土星极地附近呈绿色，是整个表面最暗的区域。根据红外观测得知，云顶温度为-170℃，比木星低50℃。土星表面的温度约为-140℃。土星表面有时会出现白斑，最著名的白斑是1933年8月发现的，这块白斑出现在赤道区，呈蛋形，长度达到土星直径的1/5.以后这个白斑不断地扩大，几乎蔓延到整个<U>[font color=#0000ff]土星表面[/font]</U>。 由于这颗行星表面温度较低而逃逸速度又大(35.6公里/秒)，使土星保留着几十亿年前它形成时所拥有的全部氢和氦。因此，科学家认为，研究土星目前的成分就等于研究太阳系形成初期的原始成分，这对于了解太阳内部活动及其演化有很大帮助。一般认为土星的化学组成像木星，不过氢的含量较少。土星上的甲烷含量比木星多，而氨的含量则比木星少。 1973年 4月美国发射的行星际探测器“先驱者”11号发现土星有一个由电离氢构成的广延电离层，其高层温度约为977℃。观测结果表明，土星极区有极光。 目前认为，土星形成时，起先是土物质和冰物质吸积，继之是气体积聚。因此，土星有一个直径20，000公里的岩石核心。这个核占土星质量的10%到20%，核外包围着5，000公里厚的冰壳，再外面是8，000公里厚的金属氢层，金属氢之外是一个广延的分子氢层。 1969年，一架飞机在地球大气高层对土星的热辐射作了红外观测，发现土星和木星一样，它辐射出的能量是它从太阳接收到的能量的两倍。这表明土星和木星一样有内在能源。后来“先驱者”11号的红外探测证实了这一点，测得土星发出的能量是从太阳吸收到的2.5倍。

Is beauty only skin deep?In life it can be hard to define terms that we use everyday. Defining beauty is one of these difficult things. When most people think of beauty they think of appearance, especially what is on the outside and most visible. However it could be argued that true beauty is deeper, more than “skin deep”. This essay will address the issue of true beauty.Most of what we see and watch around us, reinforces set stereotypes of skin deep or superficial beauty. This includes what we watch on television, the internet and advertising that surrounds us every day. Nearly all of these things reinforce the idea the beauty is only skin deep. Beautiful enticing women are used to sell us everything from food to clothing. Muscular well chiseled men try to sell us underwear, beer and aftershaveEven some advertisements purported to be discouraging beauty myths still reinforce the idea that beauty is is on the outside rather than on the inside. This “skin deep” understanding of beauty is also very pervasive, subtle and widely accepted.Christian theology affirms superficial beauty. Christians believe people are drawn to a creation made by God as good and visually beautiful. The Christian can praise God for the beautiful muscular body of the man, or the curvaceous body of a woman. The Christian can praise God for the beautiful mountains, sunset, and creation we live in.Christian theology also understands that our perception of the world is tarnished by our rejection of God as the creator. Christians understand this to mean that our view of beauty is also tarnished and that we end up worshiping the beautiful world God has given us, rather than honouring itu2019s creator. In failing to worship God first, something in our very nature looses itu2019s beauty in the process. Christians understand that itu2019s only though restored relationship with God that we can again appreciate real true beauty and begin to understand it as something that is far more than skin deep.More generally to argue that beauty is only skin deep is particularly narrow. Itu2019s difficult to believe that the average person on the street would affirm this as being true. Our society often seems torn, on the one hand we surround ourselves with set patterns and stereotypes of what true beauty is. On the other hand people always seem to seek to redefine or reject stereotypes of beauty. One evidence for this comes from the many internet memes that circulate on social media that affirm that true beauty comes from within. These are not Christian in nature suggesting that people understand that something is not quite right when it comes to how our society looks at beauty. They would seem to suggest that beauty is indeed more than skin deep.The definition of true beauty would include both internal and unseen things not just the external and seen. It could be argued that the order in which our world operates is beautiful even though we canu2019t visually “see” it. It could also be argued that things from Mathematics to feelings such as love, care and joy are all part of a world which is more than just visually or superficially beautiful.While valuing external beauty Christian theology also teaches the value of beauty that is also hidden. Christians would argue that internal unseen values such as “love”, “peace” “joy”and are beautiful, when motivated by a desire to follow Jesus. A person may very well be “ugly” on the outside but very “beautiful” on the inside. Conversely a person may be very beautiful on the outside but on the inside very, very “ugly”.In conclusion what is “true beauty”? This essay has argued that it is an internal and an external thing. Is beauty only skin deep? The answer clearly is no. Beauty in both internally and externally is affirmed both in Christian theology and the society in which we live.
