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...
Launched in 1977, the twin Voyager probes are NASA’s longest-operating mission and the only spacecraft ever to explore interstellar space. 45 years on, Voyager 1 and 2 continue to provide us with observations of the farthest reaches of space. Our Voyager 1 spacecraft zoomed toward Jupiter in January and February 1979, capturing hundreds of images of Jupiter ...
八月份的天空会发生什么？拿起你的双筒望远镜来观测行星，展望英仙座，以及和天鹅座一起翱翔。
As NASA’s Juno mission completed its 43rd close flyby of Jupiter on July 5, 2022, its JunoCam instrument captured this striking view of vortices — hurricane-like spiral wind patterns — near the planet’s north pole. These powerful storms can be over 30 miles (50 kilometers) in height and hundreds of miles across. Figuring out how they form is key to understan...
