Saturn in Infrared from Cassini

土星在紅外光下看起來略有不同。雲帶顯示出巨大的結構，包括伸展很長的風暴。 在紅外線下，土星北極周圍不尋常的六邊形雲層圖案也相當引人注目。 深色六邊形的每一邊大約相當於我們地球的寬度。六邊形的存在是無法預測的，它的起源和可能的穩定性仍然是一個研究課題。 土星著名的星環環繞著地球，在赤道下方投下陰影。這張特寫圖片是由機器人卡西尼號太空船於 2014 年拍攝的，有幾種紅外顏色。 2017 年 9 月，卡西尼號任務戲劇性地畫上了句號，飛船被指令潛入環狀巨行星。 你的天空驚喜 1995 年後
原文：Saturn looks slightly different 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. Each side of the dark hexagon spans roughly the width of our Earth. The hexagon's existence was not predicted, and its origin and likely stability remain a topics of research. Saturn's famous rings circle the planet and cast shadows below the equator. The featured image was taken by the robotic Cassini spacecraft in 2014 in several infrared colors. In 2017 September, the Cassini mission was brought to a dramatic conclusion when the spacecraft was directed to dive into the ringed giant.
