Images of Neptune taken at six wavelengths with the Hubble Space Telescope in October and November 1994 revealed several atmospheric features not present at the time of the Voyager spacecraft encounter in 1989. Furthermore, the largest feature seen in 1989, the Great Dark Spot, was gone. A dark spot of comparable size had appeared in the northern hemisphere, accompanied by discrete bright features at methane-band wavelengths. At visible wavelengths, Neptune's banded structure appeared similar to that seen in 1989.
哈勃太空望远镜于 1994 年 10 月和 11 月在六个波长处拍摄的海王星图像显示了一些在 1989 年旅行者号航天器相遇时不存在的大气特征。此外，在 1989 年看到的最大特征，大暗斑，已经消失了。在北半球出现了一个大小相当的暗斑，同时在甲烷带波长处出现了离散的亮特征。在可见光波长处，海王星的带状结构与 1989 年看到的相似。
