Swimming on Jupiter

Explanation: On October 29, the Junospacecraft once again dove near the turbulent Jovian cloud tops. Its 16thorbital closest approach or perijove passage, brought Juno within 3,500kilometers of the Solar System's largest planetary atmosphere. These frames,recorded by JunoCam while the spacecraft cruised 20 - 50 thousand kilometersabove the planet's middle southern latitudes, seem to follow a swirling cloudshaped remarkably like a dolphin. Swimming along Jupiter's darker South SouthTemperate Belt, this dolphin is itself planet-sized though, some thousands ofkilometers across.
在木星上游泳
2018年10月29日,朱诺号宇宙飞船在湍流的木星云顶附近俯冲,这也是朱诺号第16次飞越近木星点,它飞跃到太阳系最大行星大气的3500公里以内。照片是在朱诺号巡航到木星中南部纬度以上2万至5万公里高空时拍摄的,似乎是在追踪一团形状非常像海豚的旋涡云。这只海豚正沿着木星较暗的南温带游泳,不过它本身与行星一样大,直径约数千公里。
