小龙女继续说道接下来我给你们说说然而,1994年哈博望远镜对海王星的观察显示出大黑斑竟然消失了!它或许就这么消散了,或许暂时被大气层的其他部分所掩盖。几个月后哈博望远镜在海王星的北半球发现了一个新的黑斑。这表明海王星的大气层变化频繁,这也许是因为云的顶部和底部温度差异的细微变化所引起的。
其他性质
海王星的蓝色是大气中甲烷吸收了日光中的红光造成的。
作为典型的气体行星,海王星上呼啸着按带状分布的大风暴或旋风,海王星上的风暴是太阳系中最快的,时速达到2000千米。
和土星、木星一样,海王星内部有热源--它辐射出的能量是它吸收的太阳能的两倍多。
海王星的磁场和天王星的一样,位置十分古怪,这很可能是由于行星地壳中层传导性的物质(大概是水)的运动而造成的。
通过双目望远镜可观察到海王星(假如你真的知道往哪儿看),但假如你要看到行星上的一切而非仅仅一个小圆盘,那么你就需要一架大的天文望远镜。mike harvey的行星寻找图表指出此时海王星在天空中的位置(及其他行星的位置),再由starry night这个天象程序作更多更细致的定制。

海王星光环
海王星也有光环。在地球上只能观察到暗淡模糊的圆弧,而非完整的光环。但旅行者2号的图像显示这些弧完全是由亮块组成的光环。其中的一个光环看上去似乎有奇特的螺旋形结构。
同天王星和木星一样,海王星的光环十分暗淡,但它们的内部结构仍是未知数。
人们已命名了海王星的光环:最外面的是adams(它包括三段明显的圆弧,今已分别命名为自由liberty,平等equality和互助fraternity),其次是一个未命名的包有galatea卫星的弧,然后是leverrier(它向外延伸的部分叫作lassell和arago),最里面暗淡但很宽阔的叫galle。

被除名冥王星编辑
1930年由美国天文学家汤博发现的冥王星曾被认为是行星
,但2006年8月24日召开的国际天文学联合会第26届大会,经两千余天文学家表决通过———太阳系只有八大行星,不再将传统九大行星之一的冥王星视为行星,而将其列入“矮行星[3]”。[1]
冥王星被排除在大行星之外的原因:
作为行星,要满足三个条件:
一、以近似圆形的轨道围绕恒星运转。
二、质量足够大,能依靠自身引力使天体呈圆球状。
三、能逐渐清除其轨道附近的天体。
冥王星对第三条不符,且冥王星的卫星(冥卫一)过于巨大,形成了双行星系统。根据这个定义,冥王星被除名为矮行星。柯伊伯带是处于海王星轨道以外的一个太空区域,在这个区域里,到处是冰冷、岩石状的天体。公认的太阳系理论认为,海王星轨道以外天体轨道分布应该是随机的,加上观测偏差,轨道半长轴接近150天文单位,轨道倾角几乎为0°,近日点辐角也要接近0°或者180°,在柯伊伯带已发现的卡戎星、阋神星、塞德娜等十多颗极端海外天体中的轨道半长轴相差极大(介于150天文单位和525天文单位之间),轨道倾角的平均值约为20°,近日点辐角则是–31°,没有任何一个天体接近180°。这些星体的轨道参数似乎受到其他星体的影响,在海王星和冥王星以外可能还有其他未知的行星。2015年,美国的两位科学家在奥尔特云中发现了一颗矮星行星,名为2012vp113。两位发现者认为,它的轨道可能受到一颗又黑又冰的超级地球的影响,它的大小可以达到地球的10倍。[4]

高祖以周天和元年生于长安,七岁袭唐国公。及长,倜傥豁达,任性真率,宽仁容众,无贵贱咸得其欢心。隋受禅,补千牛备身。文帝独孤皇后,即高祖从母也,由是特见亲爱,累转谯、陇、岐三州刺史。有史世良者,善相人,谓高祖曰:“公骨法非常,必为人主,愿自爱,勿忘鄙言。”高祖颇以自负。大业初,为荥阳、楼烦二郡太守,征为殿内少监。九年,迁卫尉少卿。辽东之役,督运于怀远镇。及杨玄感反,诏高祖驰驿镇弘化郡,兼知关右诸军事。高祖历试中外,素树恩德,及是结纳豪杰,众多款附。时炀帝多所猜忌,人怀疑惧。会有诏征高祖诣行在所,遇疾未谒。时甥王氏在后宫,帝问曰:“汝舅何迟?”王氏以疾对,帝曰:“可得死否?”高祖闻之益惧,因纵酒沉湎,纳贿以混其迹焉。十一年,炀帝幸汾阳宫,命高祖往山西、河东黜陟讨捕。师次龙门,贼帅母端兒帅众数千薄于城下。高祖从十余骑击之,所射七十发,皆应弦而倒,贼乃大溃。十二年,迁右骁卫将军。
十三年,为太原留守,郡丞王威、武牙郎将高君雅为副。群贼蜂起,江都阻绝,太宗与晋阳令刘文静首谋,劝举义兵。俄而马邑校尉刘武周据汾阳宫举兵反,太宗与王威、高君雅将集兵讨之。高祖乃命太宗与刘文静及门下客长孙顺德、刘弘基各募兵,旬日间众且一万,密遣使召世子建成及元吉于河东。威、君雅见兵大集,恐高祖为变,相与疑惧,请高祖祈雨于晋祠,将为不利。晋阳乡长刘世龙知之,以告高祖,高祖阴为之备。
五月甲子,高祖与威、君雅视事,太宗密严兵于外,以备非常。遣开阳府司马刘政会告威等谋反,即斩之以徇,遂起义兵。甲戌,遣刘文静使于突厥始毕可汗,令率兵相应。六月甲申,命太宗将兵徇西河,下之。癸巳,建大将军府,并置三军,分为左右:以世子建成为陇西公、左领大都督,左统军隶焉;太宗为敦煌公、右领大都督,右统军隶焉。裴寂为大将军府长史,刘文静为司马,石艾县长殷开山为掾,刘政会为属,长孙顺德、刘弘基、窦琮等分为左右统军。开仓库以赈穷乏,远近响应。秋七月壬子,高祖率兵西图关中,以元吉为镇北将军、太原留守。癸丑,发自太原,有兵三万。丙辰,师次灵石县,营于贾胡堡。隋武牙郎将宋老生屯霍邑以拒义师。会霖雨积旬,馈运不给,高祖命旋师,太宗切谏乃止。有白衣老父诣军门曰:“余为霍山神使谒唐皇帝曰:‘八月雨止,路出霍邑东南,吾当济师。’高祖曰:“此神不欺赵无恤,岂负我哉!”八月辛巳,高祖引师趋霍邑,斩宋老生,平霍邑。丙戌,进下临汾郡及绛郡。癸巳,至龙门,突厥始毕可汗遣康稍利率兵五百人、马二千匹,与刘文静会于麾下。隋骁卫大将军屈突通镇河东,津梁断绝,关中向义者颇以为阻。河东水滨居人,竞进舟楫,不谋而至,前后数百人。
