以“卡西尼号”（Cassini）飞船的红外眼看来，土星（Saturn）优美的云层有时就像是这个巨大行星的一幅印象派画作。
这幅图像的视角位于光环面上方18度，朝向光环的光照面。图像由“卡西尼号”飞船的广角相机摄于8月12日，采用了对728纳米波段近红外光敏感的光谱滤波器。
“卡西尼号”距离土星约160万公里。该图像的比例为每像素92千米。
“卡西尼-惠更斯”使命（Cassini-Huygens mission）是美国国家航空航天局（NASA）、欧洲航天局（European Space Agency）和意大利航天局（Italian Space Agency）的合作项目。关于“卡西尼-惠更斯”使命的更多信息，请访问 http://www.nasa.gov/cassini 和http://saturn.jpl.nasa.gov.

Cassini’s Impressionistic View of Saturn
http://photos.state.gov/libraries/amgov/3234/Week_3/11202013_PIA17127_ip-600.jpg
To the Cassini spacecraft’s infrared eyes, Saturn’s graceful clouds sometimes take on the appearance of an impressionist’s painting of the giant planet.
This view looks toward the sunlit side of the rings from about 18 degrees above the ringplane. The image was taken with the Cassini spacecraft’s wide-angle camera on August 12, using a spectral filter sensitive to wavelengths of near-infrared light centered at 728 nanometers.
Cassini was about 1.6 million kilometers from Saturn. The image scale is 92 kilometers per pixel.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. For more information about the Cassini-Huygens mission, visit http://www.nasa.gov/cassini and http://saturn.jpl.nasa.gov.
