Jupiters Clouds of Many Colors
Jupiters Clouds of Many Colors

NASAs Juno spacecraft was racing away from Jupiter following its seventh close pass of the planet when JunoCam snapped this image on May 19, 2017, from about 29,100 miles (46,900 kilometers) above the cloud tops. The spacecraft was over 65.9 degrees south latitude, with a lovely view of the south polar region of the planet.
This image was processed to enhance color differences, showing the amazing variety in Jupiters stormy atmosphere. The result is a surreal world of vibrant color, clarity and contrast. Four of the white oval storms known as the "String of Pearls" are visible near the top of the image. Interestingly, one orange-colored storm can be seen at the belt-zone boundary, while other storms are more of a cream color.

Jupiters Aurora
Jupiters Aurora

This ultraviolet image of Jupiter was taken with the Hubble Space Telescope Imaging Spectrograph (STIS) on 26 November 1998 and gives a good impression of the observations that Hubble will make in the weeks to come. The bright emissions above the dark blue background are auroral lights, similar to those seen above the Earths polar regions. The aurorae are curtains of light resulting from high energy electrons following the planets magnetic field into the upper atmosphere, where collisions with atmospheric atoms and molecules produce the observed light. On Jupiter one can normally see three different types of auroral emissions:
a) a main oval, centred on the magnetic north pole
b) a pattern of more diffuse emissions inside the polar cap and
c) a unique auroral feature showing the magnetic footprints of three of Jupiters satellites. These footprints can be seen in this image: from Io (along the left-hand limb), from Ganymede (near the centre just below the reference oval) and from Europa (just below and to the right of Ganymedes auroral footprint). These emissions are unlike anything seen on Earth and are produced by electric currents generated at the satellites that then flow along Jupiters magnetic field, weaving in and out of its upper atmosphere.
This incredibly detailed image was taken on November 26 1998 when Jupiter was at a distance of 700 million km from Earth. The image was taken in UV light at 140 nm.

Jupiters Great Red Spot
Jupiters Great Red Spot

This enhanced-color image of Jupiters Great Red Spot was created by citizen scientist Gerald Eichst�dt using data from the JunoCam imager on NASAs Juno spacecraft.
The image is approximately illumination adjusted and strongly enhanced to draw viewers eyes to the iconic storm and the turbulence around it.
The image was taken on July 10, 2017 at 07:07 p.m. PDT (10:07 p.m. EDT), as the Juno spacecraft performed its 7th close flyby of Jupiter. At the time the image was taken, the spacecraft was about 6,130 miles (9,866 kilometers) from the tops of the clouds of the planet.

Jupiters Great Red Spot and Earth
Jupiters Great Red Spot and Earth

Measuring in at 10,159 miles (16,350 kilometers) in width (as of April 3, 2017) Jupiters Great Red Spot is 1.3 times as wide as Earth. This composite image was generated by combining NASA imagery of Earth with an image of Jupiter taken by astronomer Christopher Go.

Jupiters Clouds
Jupiters Clouds

This enhanced-color image of Jupiters bands of light and dark clouds was created by citizen scientists Gerald Eichst�dt and Se�n Doran using data from the JunoCam imager on NASAs Juno spacecraft.
Three of the white oval storms known as the "String of Pearls" are visible near the top of the image. Each of the alternating light and dark atmospheric bands in this image is wider than Earth, and each rages around Jupiter at hundreds of miles (kilometers) per hour. The lighter areas are regions where gas is rising, and the darker bands are regions where gas is sinking.
Juno acquired the image on May 19, 2017, at 11:30 a.m. PST (2:30 p.m. EST) from an altitude of about 20,800 miles (33,400 kilometers) above Jupiters cloud tops.
