Voyager 2 images of Neptune reveal a windy planet characterized by bright clouds of methane ice suspended in an exceptionally clear atmosphere above a lower deck of hydrogen sulfide or ammonia ices. Neptune's atmosphere is dominated by a large anticyclonic storm system that has been named the Great Dark Spot (GDS). About the same size as Earth in extent, the GDS bears both many similarities and some differences to the Great Red Spot of Jupiter. Neptune's zonal wind profile is remarkably similar… 
Comparative CFD Simulations of the Dark Spots of Uranus and Neptune
Farther out and smaller than Jupiter and Saturn, Neptune and Uranus are less frequently observed gas-giant planets in the outer solar system. However, like the better known Great Red Spot and the new
Winds of Neptune - Voyager observations of cloud motions
High temporal and spatial resolution images acquired from Voyager cameras have been used to measure cloud motions to improve the meridional profile of the zonal mean circulation on Neptune. A wide
Orographic Cloud Development Paired with Atmospheric Vortex Dynamics on Uranus and Neptune
Large geophysical vortices provide some of the most dramatic atmospheric features in the solar system. Common examples include terrestrial hurricanes and the Great Red Spot of Jupiter, but similar
Origin of Aurora and Airglow on the Night Side of Neptune
We have examined the latitude-longitude distribution of emissions detected by the Voyager ultraviolet spectrometer on the dark hemisphere of Neptune, The emissions have two significant geographic
Neptune's small inner satellites
Voyager 2 images revealed six small satellites orbiting within five planetary radii of Neptune. The largest, Proteus (1989N1), has a mean radius of 208 ± 8 km; the smallest, Naiad (1989N6), is 29 ± 6
Analysis of Neptune’s 2017 bright equatorial storm
Uranus and Neptune
Uranus and Neptune, were the first planets discovered by telescopic observation. They are of Jovian Planets similar size and much more massive than Earth (by factors of 14.5 and 17) but are still far
Scientific rationale for Uranus and Neptune in situ explorations


Voyager 2 in the Uranian System: Imaging Science Results
Voyager 2 images of the southern hemisphere of Uranus indicate that submicrometersize haze particles and particles of a methane condensation cloud produce faint patterns in the atmosphere, and Voyager images confirm the extremely low albedo of the ring particles.
The Galilean Satellites and Jupiter: Voyager 2 Imaging Science Results
Voyager 2, during its encounter with the Jupiter system, provided images that both complement and supplement in important ways the Voyager 1 images, which revealed a complex and, as yet, little-understood system of overlapping bright and dark linear features.
Photometry from Voyager 2: Initial Results from the Neptunian Atmosphere, Satellites, and Rings
The Voyager photopolarimeter successfully accomplished its objectives for the Neptune encounter, performing measurements on the planet, several of its satellites, and its ring system, and showing evidence of two major compositional units on its surface.
Encounter with saturn: voyager 1 imaging science results.
As Voyager 1 flew through the Saturn system it returned photographs revealing many new and surprising characteristics of this complicated community of bodies, including small inner satellites that interact gravitationally with one another and with the ring particles in ways not observed elsewhere in the solar system.
A New Look at the Saturn System: The Voyager 2 Images
Within Saturn's rings, the "birth" of a spoke has been observed, and surprising azimuthal and time variability is found in the ringlet structure of the outer B ring, leading to speculations about Saturn's internal structure and about the collisional and thermal history of the rings and satellites.
Voyager Radio Science Observations of Neptune and Triton
The Voyager 2 encounter with the Neptune system included radio science investigations of the masses and densities of Neptune and Triton, the low-order gravitational harmonics of Neptune, the vertical
Discrete cloud structure on Neptune
Creation of the Uranus rings and dust bands
VOYAGER observations of the extended hydrogen exosphere of Uranus and of the σ Ring and its shepherds set an upper limit to the age of the σ Ring of 6 × 108 years. Unless we are seeing Uranus at a
Ultraviolet Spectrometer Observations of Neptune and Triton
Results from the occultation of the sun by Neptune imply a temperature of 750 � 150 kelvins in the upper levels of the atmosphere (composed mostly of atomic and molecular hydrogen) and define the
Neptune's Wind Speeds Obtained by Tracking Clouds in Voyager Images
Images of Neptune obtained by the narrow-angle camera of the Voyager 2 spacecraft reveal large-scale cloud features that persist for several months or longer, and wind speeds computed with respect to this radio period are roughly the same for all the planets ranging from Venus to Neptune.
