Saturn's rings were seen in 1610
1610年已觀測到土星光環(huán)

      In 1610, Galileo Galilei became the first person to observe Saturn's rings; however, he described them as "ears." It was not until 1655 that Christian Huygens was able to use his higher-quality telescope to become the first person to describe the feature as an actual ring surrounding Saturn. Finally, in 1675, Giovanni Cassini determined that Saturn's "ring" was actually composed of subrings with gaps between them.
      1610年伽利略就已經(jīng)是第一個(gè)觀測到土星光環(huán)的人了，不過當(dāng)時(shí)他把光環(huán)稱之為“耳朵”。直到1655年，克里斯蒂安·惠更斯才使用更高倍的望遠(yuǎn)鏡觀察土星，并對土星光環(huán)的性質(zhì)做了具體描述。最終，在1675年，意大利天文學(xué)家卡西尼才確定了土星光環(huán)是由子環(huán)和其間的空隙所構(gòu)成的。
