2023年11月28日 Ganymede from Juno Image Credit & Copyright: NASA/JPL-Caltech/SwRI/MSSS; Processing & License: Kevin M. Gill; Explanation: What does the largest moon in the Solar System look like? Jupiter‘s moon Ganymede, larger than even Mercury and Pluto, has an icy surface speckled with bright young craters overlying a mixture of older, darker...
2023年10月23日 Moon Io from Spacecraft Juno Image Credit: NASA, JPL-Caltech, SwRI, MSSS; Processing & Copyright: Ted Stryk & Fernando García Navarro Explanation: There goes another one! Volcanoes on Jupiter‘s moon Io keep erupting. To investigate, NASA‘s robotic Juno spacecraft has begun a series of visits to this very strange moon. Io is ...
2023年6月25日 Lightning on Jupiter Image Credit: NASA/JPL-Caltech/SwRI/MSSS; Processing & License: Kevin M. Gill Explanation: Does lightning occur only on Earth? No. Spacecraft in our Solar System have detected lightning on other planets, including Mars, Jupiter and Saturn, and lightning is likely on Venus, Uranus, and Neptune. Lightning is a sudden rush o...
2023年5月23日 Jupiter’s Swirls from Juno Image Credit: NASA/JPL-Caltech/SwRI/MSSS; Processing & License: Kevin M. Gill Explanation: Big storms are different on Jupiter. On Earth, huge hurricanes and colossal cyclones are centered on regions of low pressure, but on Jupiter, it is the high-pressure, anti-cyclone storms that are the largest. On Earth, l...
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...
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...
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...
A new NASA citizen science project, Jovian Vortex Hunter, seeks your help spotting vortices – spiral wind patterns – and other phenomena in photos of the planet Jupiter. Another NASA citizen science project, called Junocam, seeks help from members of the public processing images from NASA’s Juno Mission and choosing targets for the spacecraft. However, the n...
这张JunoCAMM照片显示了木星的两个大型旋转风暴，是在朱诺号于2021年11月29日第38次经过木星时拍摄的。 影像来源：NASA/JPL-Caltech/SwRI/MSSS 图像处理：KEVIN M. GILL CC by 朱诺号在木星任务的木卫三飞掠期间收集的音轨提供了一个戏剧性的旅程。这是任务科学家在美国地球物理联盟秋季会议简报会上分享的亮点之一。 今天在新奥尔良举行的美国地球物理学会秋季会议上，在关于NASA朱诺号木星任务的简报中讨论了来自木卫二飞越的声音、磁场以及木星和地球海洋和大气之间的显著比较。 今天，在新奥尔良举行的美国地球物理联盟秋季会议上，关于NASA朱诺号木星任务的简报会上，讨论了木卫三飞行的声音、磁场以及木星与地球海洋和大气层之间的显著对比。 位于圣安东尼奥的西南研究所的朱诺号首席研...
