文章掠影:
此圖中我們看到是土星的天然本色,如此壯麗輝煌,使其旁邊冰冷的衛(wèi)星Rhea(譯注:土衛(wèi)五)相形見絀。
英文原文:
Saturn, stately and resplendent in this natural color view, dwarfs its icy moon Rhea.
Rhea (949 miles in diameter) orbits beyond the rings on the right of the image. The moon Tethys is not shown here, but its shadow is visible on the planet on the left of the image. This view looks toward the northern, sunlit side of the rings from just above the ringplane.
Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were obtained with the Cassini spacecraft wide-angle camera on Nov. 4, 2009, at a distance of approximately 808,000 miles from Saturn.
參考譯文:
此圖中我們看到是土星的天然本色,如此壯麗輝煌,使其旁邊冰冷的衛(wèi)星Rhea(譯注:土衛(wèi)五)相形見絀。
Rhea(直徑969英里)在土星光環(huán)外的軌道上運(yùn)行,它出現(xiàn)在這幅圖像的右側(cè)。衛(wèi)星Tethys(譯注:土衛(wèi)三)在此圖中沒有出現(xiàn),但我們可以在圖像左側(cè)清晰看它落在土星表面上的影子。此圖的視角是朝向北方的,土星光環(huán)朝向太陽的一面正位于光環(huán)平面的上方。
此圖中我們看到的土星的自然的色彩是使用了紅色、綠色和藍(lán)色光譜濾鏡合成出來的。此圖是卡西尼太空飛船于2009年11月4日,在距土星大約808000英里處,通過寬視角照相機(jī)拍攝的。 |
