一跃而下,探索木星大气深处

解释:跟着我们的视频来模拟一次高空跳吧,让我们一头扎进木星(太阳系最大的气态巨行星)外围的大气!根据“朱诺”号木星探测器上搭载的高清相机(JunoCam)和微波辐射计所收集到的影像数据,我们制作出了这部超棒的动画。在这部动画里,你最初的视野高度约为木星南半球云顶上方3000千米,查看左侧的进度条即可随时跟进自己的位置高度。当你下冲进入木星著名的风暴系统“大红斑”时,你会发现,冲得越深,温度越高。根据“朱诺”号传来的数据,“大红斑”这个太阳系最大的风暴系统大致处于木星大气300千米深处。相比之下,地球上海洋的最深之处其实一点也不深,仅在地球外层大气下11千米处。不过别慌啊,再深你也不至于飞不出来哈。

Jupiter Diving

Explanation: Take this simulated plunge and dive into the upper atmosphere of Jupiter, the Solar System’s ruling gas giant. The awesome animation is based on image data from JunoCam, and the microwave radiometer on board the Jupiter-orbiting Juno spacecraft. You’re view will start about 3,000 kilometers above the southern Jovian cloud tops, but you can track your progress on the display at the left. As altitude decreases, temperature increases while you dive deeper at the location of Jupiter’s famous Great Red Spot. In fact, Juno data indicates the Great Red Spot, the Solar System’s largest storm system, penetrates some 300 kilometers into the giant planet’s atmosphere. For comparison, the deepest point for planet Earth’s oceans is just under 11 kilometers down. Don’t panic though, you’ll fly back out again.
