Voyager 2 spacecraft false-colour image of the planet Neptune,taken during August 1989,when Voyager passed within 5,000 km of Neptune's north pole. This false-colour image,obtained using the ultraviolet,violet and green filters of Voyager's wide-angle camera,highlights details of weather systems,revealing clouds located at different altitudes in different colours. The prominent Great Dark Spot (centre),a giant storm system the size of Earth,appears surrounded by pink,wispy clouds at high altitudes. Areas of dark,deep- lying cloud appear dark blue in this image |
