A large poster print of Neptune.
View of a Neptune with its rings. Image of rings was created by using information gathered by Voyager 2.

Image Notes:

The larger image was created by the Voyager 2 satellite on September 21, 1989. The only satellite to have visited Neptune. At the time that image was taken a dark spot was seen was seen on its surface similar to the Great Red Spot on Jupiter. On November 2, 1994, the Hubble telescope took images of Neptune and did not find the dark spot, instead a different storm was seen. It is thought that these storms may last only for months and then disappear as the get closer to the equator. The reason for this remains unknown.

Image Credit: NASA/ Image of rings was created by us here at using information gatherd by Voyager 2.
