Click to view the full image of the icon which I use for most things. This image of Neptune's rings was made from two ten-minute exposures 1.5 hours apart. Voyager 2 took this image in 1989 while 280,000 kilometers away from Earth.
The official label is ARC-1989-A89-7045 (or PIA01997), and you can access it here (archive), or at the NASA Image and Video library archive, and the full image here (archive 1, archive 2). Below are three more Neptune-related images taken by Voyager 2, found here (archive).
