2023年3月31日 Seeing Titan Image Credit: VIMS Team, U. Arizona, U. Nantes, ESA, NASA Explanation: Shrouded in a thick atmosphere, Saturn’s largest moon Titan really is hard to see. Small particles suspended in the upper atmosphere cause an almost impenetrable haze, strongly scattering light at visible wavelengths and hiding Titan’s surface features ...

2023年2月5日 Enceladus by Saturnshine Image Credit: NASA; ESA, JPL, Cassini Imaging Team, SSI; Color Composite: Gordan Ugarkovic Explanation: This moon is shining by the light of its planet. Specifically, a large portion of Enceladus pictured here is illuminated primarily by sunlight first reflected from the planet Saturn. The result is that the normally snow-w...

2022年12月23日 Cassini Looks Out from Saturn Image Credit: NASA, JPL-Caltech, Space Science Institute Explanation: This is what Saturn looks like from inside the rings. In 2017, for the first time, NASA directed the Cassini spacecraft to swoop between Saturn and its rings. During the dive, the robotic spacecraft took hundreds of images showing unprecedented det...

2022年7月24日 Saturn in Infrared from Cassini Image Credit: NASA, JPL-Caltech, SSI; Processing: Maksim Kakitsev Explanation: Many details of Saturn appear clearly in infrared light. Bands of clouds show great structure, including long stretching storms. Also quite striking in infrared is the unusual hexagonal cloud pattern surrounding Saturn’s North Pole....
土星、土卫三、行星环及暗影
2022年1月23日 Saturn, Tethys, Rings, and Shadows Image Credit: Cassini Imaging Team, SSI, JPL, ESA, NASA Explanation: Seen from ice moon Tethys, rings and shadows would display fantastic views of the Saturnian system. Haven’t dropped in on Tethys lately? Then this gorgeous ringscape from the Cassini spacecraft will have to do for now. Caught in sunlight j...
土星环后方的卫星
2022年1月4日 Moons Beyond Rings at Saturn Image Credit: NASA, ESA, JPL, Cassini Imaging Team Explanation: What’s happened to that moon of Saturn? Nothing — Saturn’s moon Rhea is just partly hidden behind Saturn’s rings. In 2010, the robotic Cassini spacecraft then orbiting Saturn took this narrow-angle view looking across the Solar Syste...
