2022年10月25日 Jupiter Rotates as Moons Orbit Video Credit & Copyright: Makrem Larnaout Explanation: Jupiter and its moons move like our Sun and its planets. Similarly, Jupiter spins while its moons circle around. Jupiter’s rotation can be observed by tracking circulating dark belts and light zones. The Great Red Spot, the largest storm known, rotates to b...
During its 40th close pass by Jupiter, our Juno spacecraft saw Ganymede cast a large, dark spot on the planet on Feb. 25, 2022. JunoCam captured this image from very close to Jupiter, making Ganymede’s shadow appear especially large. At the time the raw image was taken, the Juno spacecraft was about 44,000 miles (71,000 kilometers) above Jupiter’s cloud tops...
2022年10月7日 In Ganymede’s Shadow Image Credit & Copyright: Andrew McCarthy Explanation: At opposition, opposite the Sun in Earth’s sky, late last month Jupiter is also approaching perihelion, the closest point to the Sun in its elliptical orbit, early next year. That makes Jupiter exceptionally close to our fair planet, currently resulting in...
2022年10月3日 Jupiter’s Europa from Spacecraft Juno Image Credit & License: NASA, JPL-Caltech, SwRI, MSSS; Processing: Andrea Luck Explanation: What mysteries might be solved by peering into this crystal ball? In this case, the ball is actually a moon of Jupiter, the crystals are ice, and the moon is not only dirty but cracked beyond repair. Neverthe...
十月份的天空会发生什么？夜晚有巨行星，火星改变方向，来自猎户座的流星。
九月份的天空会发生什么？火星在移动，木星的最佳观测时间，以及一个在秋分点寻找方位的巧妙方法。
Auroras and hazes glow in this composite image of Jupiter taken by the James Webb Space Telescope’s Near-Infrared Camera (NIRCam). NIRCam has three specialized infrared filters that showcase details of the planet. Since infrared light is invisible to the human eye, the light has been mapped onto the visible spectrum: the auroras are mapped to redder co...
2022年8月30日 Jupiter from the Webb Space Telescope Image Credit: NASA, ESA, CSA, Jupiter ERS Team; Processing: Ricardo Hueso (UPV/EHU) & Judy Schmidt Explanation: This new view of Jupiter is illuminating. High-resolution infrared images of Jupiter from the new James Webb Space Telescope (Webb) reveal, for example, previously unknown differences between hi...
2022年8月28日 Perijove 11: Passing Jupiter Video Credit: License: NASA, Juno, SwRI, MSSS, Gerald Eichstadt; Music: Moonlight Sonata (Ludwig van Beethoven) Explanation: Here comes Jupiter! NASA’s robotic spacecraft Juno is continuing on its highly-elongated orbits around our Solar System’s largest planet. The featured video is from perijove 11 in ear...
我们的阿尔忒弥斯一号飞行测试 “准备发射”…… 第一次深空长时间生物测试… 韦伯太空望远镜捕捉到了木星的新图像…… 最近新闻速递，尽在「本周NASA」！ 影像来源：NASA 翻译：灼眼的粉丝 阿尔忒弥斯一号任务已做好飞行准备，”准备发射！” 8月22日，任务经理结束了对阿尔忒弥斯一号无人飞行试验的飞行准备审查，向各团队发出了 “开始发射 “的命令。 该审查是对我们的太空发射系统火箭和猎户座航天器支持阿尔忒弥斯一号飞越月球和返回地球飞行测试的准备情况的深入评估。这次任务的主要目标在宇航员执行后续阿尔忒弥斯任务之前，从发射到溅落，彻底测试综合系统。阿尔忒弥斯一号任务目前的目标是不早于8月29日发射。 第一次深空生物任务 生物哨兵（BioCont...
