面望远镜观测结果，分析后发现：木卫一表面炽热熔岩中钠和钾，正在蒸发成气体进入大气中。此外他们还发现一氧化硅则是熔岩中硅类气体的主要成分； 由于天文学家在太空中已观测到一氧化硅的存在，尤其是表面温度较冷的恒星大气中，因此使得木卫一表面一氧化硅的发现显得格外引人注目，他们还希望 能在火山喷出的气体中直接侦测到一氧化硅气体。相关研究成果发表在年月份的《伊卡鲁斯》杂志中（行星科学的主要刊物）。是太阳系最炽热的卫星木卫 一照片拼接图木卫一照片拼接图年，天文学家们研究发现，太阳系内（除太阳外）最炽热的星体并不是人们一贯认为的距离太阳最近的行星水星和金星，而 是木星的卫星木卫一（木星最明亮的四颗卫星之一，年前由伽利略最先发现）。当然，使得木卫一有如此之高的温度并不是太阳辐射的功劳，而是它内部剧 烈火山活动的结果。在； 马自达3 /product/mazda3/ ；太阳系内部，再没有任何其它行星或卫星能与木卫一在火山数量 上相媲美。天文学家们首次发现木卫一上强烈的火山活动是在多年前，当时美国的“旅行者”号星际探测器曾给木卫一拍摄了一系列照片。此后，在木星附 近工作了约8年的“伽利略”号探测器还为这颗炽热的卫星进行了近距离拍照。正是以这些照片为依据科学家们确定了木卫一上有着非常剧烈的火山活动，其 表面温度可达摄氏度。来自圣路易斯华盛顿大学的研究人员对木卫一上的火山喷发进行的计算机模拟实验显示，木卫一火山爆发喷射出的熔岩能够将其表面 的钠、钾、硅、铁等物质及其化合物熔化并蒸发到大气中。这些物质的气化物与火山岩气体（含亚硫化物及氯化物）发生反应便形成了木卫一大气特有的组 成成份：钠和钾的氯化物以及镁和铁的二氯化物。气态氯化钠在木卫一上已经找到，就条件来看，要找到气态氯化钾我们的探测器的灵敏度还需要加以改进。 尽管科学家们已经获取了有关木卫一的许多资料，但凭这些资料还远远不能让科学家们揭开木卫一神秘的面纱：这颗大小仅与月球相当的卫星如何保持如此 之高的岩浆温度？如此高温的岩浆却为何熔化不了其周围的岩石？它的岩石圈（包括地壳和地幔上部）到底有多厚多坚固？如果它上面有山，其高度会不会 赛过珠穆朗玛峰？当然，要解开这一系列的疑惑尚需要天文学家们持续不断的努力。[]火山爆发频繁木星与木卫一木星与木卫一科学家研究发现太阳系最活 跃的火山即将爆发，而火山爆发活动频繁的木卫在未来的某一天将可能休眠。此前，离木星距离最近一颗大卫星木卫一已多次出现火山爆发活动，其表层被 火山灰覆盖，其表面还有数十个活火山。而木卫一的大小和:
