2017年11月28日:朱诺号见到的複杂木星风暴系统-(Juno Spots a Complex Storm on Jupiter)
2017年11月28日:朱诺号见到的複杂木星风暴系统-(Juno Spots a Complex Storm on Jupiter)--原图下载{mtitle title="朱诺号见到的複杂木星风暴系统"/}Image Credit: NASA, JPL-Caltech, SwRI, MSSS; Processing &License:Gerald Eichst�dt & Se�n Doran说明: 有些木星风暴极其複杂。上面这个涡旋状风暴系统,是在上个月由美国航太总署,目前正在绕行太阳系最大的行星(木星)的朱诺号太空船所记录。这幅主题影像的宽度大约是30,000公里,因此这个风暴系统的跨度和地球相当。这个扰动逆时钟旋转,而且其云型带有咸认主要是由氨冰所构成的淡色上升气流。这些淡色云除了高度最大之外,甚至还在右方投射出清楚可辨的影子。在接下来的数年之中,朱诺号将持续绕行和探索木星并回传数据,以协助人类深入了解木星的大气水汽含量,以及在这颗行星有趣的云层之下,是否有个固态的表面。{lamp/}原文:{mtitle title="Juno Spots a Complex Storm on Jupiter"/}Image Credit: NASA, JPL-Caltech, SwRI, MSSS; Processing &License:Gerald Eichst�dt & Se�n DoranExplanation: Some storms on Jupiter are quite complex.The swirling storm was captured late last month by the NASA's robotic Juno spacecraft currently orbiting the Solar System's largest planet. The featured image spans about 30,000 kilometers, making this storm system just about as wide as planet Earth. The disturbance rotates counter-clockwise and shows a cloud pattern that includes light-colored updrafts thought to be composed predominantly of ammonia ice. These light clouds are the highest up and even cast discernable shadows toward the right. Juno will continue to orbit and probe Jupiter over the next few years as it tries to return data that help us to better understand Jupiter's atmospheric water abundance and if the planet has a solid surface underneath these fascinating clouds.

2011年10月22日:往「冲」靠近的木星-(Jupiter Near Opposition)
2011年10月22日:往「冲」靠近的木星-(Jupiter Near Opposition)--原图下载{mtitle title="往「冲」靠近的木星"/}Image Credit &Copyright: S2P/IMCCE/Obs. Midi Pyrénées,Jean-Luc Dauvergne,Francois Colas说明: 在今年10月29日 (UT)的地球天空中,太阳系最大的行星-木星将运行到「冲」 (opposition)的位置,因此在日落时,明亮的木星将从东方昇起。在这个特殊的位置,木星将是近一年来最靠近地球;因此在冲附近,地球望远镜能见到木星纷乱的带状大气和巨大的伽利略卫星。在张10月13日的木星清晰影像,是由法国庇里牛斯山 (French Pyrenees)Pic Du Midi天文台的一米望远镜所拍摄。这幅北方在顶端的影像,除了呈现了木星椭图状的气旋和平行于赤道的亮暗相间云带之外,亦可见到从木星后方昇起的冰质木卫三 (Ganymede;太阳系最大卫星),以及左下角的火山卫星木卫一 (Io)。{lamp/}原文:{mtitle title="Jupiter Near Opposition"/}Image Credit &Copyright: S2P/IMCCE/Obs. Midi Pyrénées,Jean-Luc Dauvergne,Francois ColasExplanation: OnOctober 29 (UT), Jupiter,thesolar system's largest planet, will be at opposition,opposite the Sun in planet Earth's sky,shining brightly and rising as the Sun sets.Thatconfiguration results in Jupiter's almost annualclosest approach to planet Earth, so near oppositionthe gas giant offers earthbound telescopes stunning views of itsstormy, banded atmosphere and largeGalilean moons.This sharp snapshot of Jupiter was captured on October 13 with the1 meter telescopeat the Pic Du Midimountain top observatory in theFrench Pyrenees.North is up in the image that shows off oval shaped vorticesand planet girdlingdark beltsand light zones.Also seen in remarkable detail, Jupiter'sicy Ganymede,the solar system's largest moon, is emerging frombehind the planet (top) whilevolcanic Ioenters the frame near the lower left edge.

2011年08月09日:Juno探测船航向木星-(Juno Rockets Toward Jupiter)
2011年08月09日:Juno探测船航向木星-(Juno Rockets Toward Jupiter)--原图下载2011 August 9 {mtitle title="Juno探测船航向木星"/}Video Credit: NASA说明: 下一站:木星。上周又是一次历史性的发射任务,火箭以太空船无法再回头的高速,航向外太空。嗯,其实是几乎不会回头的速度。事实上,Juno的航道计画在两年后靠近地球,利用地球重力推进到更高的速度,使其足以抵达木星。影片中,Atlas V火箭搭载着Juno升空。当<ahref="http://www.youtube.com/watch?v=VG7pRfTvDxs">Juno探测船在2016年抵达木星后,预订绕行这颗太阳系最大的行星一年以上,利用唯一个核心仪器来探测行星,并将木星的原始资料与结构资讯传送回来。最后,Juno将会潜入到浓厚的木星大气里,在Juno高温融化摧毁之前,竭尽所能的撷取数据。{lamp/}原文:{mtitle title="Juno Rockets Toward Jupiter"/}Video Credit: NASAExplanation: Next stop:Jupiter.Last week included one of the few times in history thathumanity launchedsomething completely off the Earth, moving away so fast that it will never return. Well, almost --Juno's planned trajectory actually brings it homeward bound in about two years, zipping by, this time using the Earth'sgravity to pullit to an even higher speed, high enough toreach Jupiter.The above video depicts the launch of Juno aboard aAtlas V rocket.When the roboticJun<ahref="http://www.youtube.com/watch?v=VG7pRfTvDxs">o spacecraft reaches Jupiter in 2016, it will spend just over a year circling the Solar System'slargest planet, using its unique cadre of instruments to probe the planet,sending back clues of its structure and origin.ThenJuno will be instructed to dive into the thick atmosphere of the Jovian giant, taking as much data as it can before it melts.
