Jupiter-Juno-2024-6.jpgGas Storms99 visiteSome background information: after a journey lasting more than five years, the Juno spacecraft arrived in orbit around Jupiter on July 4, 2016. Distance from Earth: 1.74 billion miles. On October 24, it performed its eighth close flyby, passing through the planet's cloud cover and approaching to within just 3,400 kilometers of Jupiter's surface. Its mission? To collect data and images of the largest planet in our Solar System to transmit to Earth.
After a delay (Initial Phase) in data transmission, due to a solar conjunction in which communications between Jupiter and Earth were interrupted by its excessive proximity to the sun, the information, stored within the Juno probe, arrived at NASA, and the results are astonishing. The images show the planet's mysterious North and South Poles, as well as gigantic gas storms.
While we wait for new Fly-Vyes, we show you some beautiful images transmitted by the probe relating to the gas giant, the fifth planet of the Solar System.MareKromium

Jupiter-Juno-2024-Fra-5.jpgTurbulence Atmosphérique105 visiteQuelques informations de base : aprs un voyage de plus de cinq ans, la sonde Juno s'est mise en orbite autour de Jupiter le 4 juillet 2016. Distance de la Terre : 2,8 milliards de kilomtres. Le 24 octobre, elle a effectu son huitime survol rapproch, traversant la couche nuageuse de la plante et s'approchant seulement 3 400 kilomtres de sa surface. Sa mission ? Collecter des donnes et des images de la plus grande plante de notre systme solaire afin de les transmettre la Terre.
Aprs un retard (phase initiale) dans la transmission des donnes, d une conjonction solaire durant laquelle les communications entre Jupiter et la Terre ont t interrompues par la proximit excessive de la plante avec le Soleil, les informations, stockes bord de la sonde Juno, sont parvenues la NASA, et les rsultats sont stupfiants. Les images rvlent les mystrieux ples Nord et Sud de la plante, ainsi que d'immenses temptes de gaz.
En attendant de nouvelles images, nous vous prsentons quelques magnifiques clichs transmis par la sonde, concernant cette gante gazeuse, la cinquime plante du systme solaire.MareKromium

Jupiter-Juno-Lightning_Green.jpgGreen Light on Jupiter93 visiteIf that "Green Thing" is a true Lightning, then it is a VERY funny-looking one. But we are on Jupiter and so, everything is possible! At least, so the Scientists said, swearing on the Third Newton's Law.MareKromium

Jupiter-PIA01384.jpgThe Great Red Spot, from Voyager 164 visiteOriginal caption:"This view of Jupiter was taken by Voyager 1. This image was taken through color filters and recombined to produce the color image.
This photo was assembled from three black and white negatives by the Image Processing Lab at Jet Propulsion Laboratory".

Jupiter-PIA02401.jpgLook at Me!74 visiteWhen 17th-century astronomers first turned their telescopes to Jupiter, they noted a conspicuous reddish spot on the Giant Planet. This Great Red Spot is still present in Jupiter's atmosphere, more than 300 years later. It is now known that it is a vast storm, spinning like a cyclone. Unlike a low-pressure hurricane in the Caribbean Sea, however, the Red Spot rotates in a counterclockwise direction in the Southern Hemisphere, showing that it is a high-pressure system. Winds inside this Jovian storm reach speeds of about 270 mph.
The Red Spot is the largest known storm in the Solar System. With a diameter of about 15.400 miles, it is almost twice the size of the entire Earth and 1/6th the diameter of Jupiter itself.
The long lifetime of the Red Spot may be due to the fact that Jupiter is mainly a gaseous planet. It possibly has liquid layers, but lacks a solid surface, which would dissipate the storm's energy, much as happens when a hurricane makes landfall on the Earth. However, the Red Spot does change its shape, size, and color, sometimes dramatically. Such changes are demonstrated in high-resolution Wide Field and Planetary Cameras 1 & 2 images of Jupiter obtained by NASA's Hubble Space Telescope between 1992 and 1999(PIA01594 thru PIA01599 and PIA02400 thru PIA02402). This image was obtained in April 1997.

Jupiter-PIA02865-1.JPGJupiter's clouds - 619 nnmts filter63 visiteThe images shown here demonstrate the power of these filters in studies of cloud stratigraphy. The images cover latitudes from about 15 North at the top down to the Southern Polar Region at the bottom. (...)
The most prominent feature seen in all 3 filters is the Polar Stratospheric Haze that makes Jupiter bright near the Pole. The equatorial band is also very bright in the strong 890-nnmts image and to a lesser extent in the 727 band, but is subdued in the weak 619-nnmts image. These are high, thin, haze layers that are nearly transparent at wavelengths outside the methane absorption bands.
Another prominent feature is the Great Red Spot: about a third of it appears at the right-hand edge of the frame.
It is a bright feature in methane absorption because it has extensive cloud cover reaching to high altitude.
A wisp of high thin cloud can be seen trailing off its western rim in the 2nd and 3rd image.

Jupiter-PIA02865-2.JPGJupiter's clouds - 727 nnmts filter76 visiteAll the already mentined Jovian features have also been seen from ground-based telescopes, from NASA's HST and from NASA's Galileo spacecraft.
Chief among these features is the very dark patch seen in the weak methane image (619 nnmts) near the top-middle of the frame.
It is almost invisible in the next image (890 nnmts) and it appears to be composed of strands of bright clouds in this frame (727 nnmts).
This is a Region similar to the "hot spot" where the Galileo Probe entered Jupiter's atmosphere in 1995.
These images indicate that cloud cover is present at the higher altitudes but absent from the lower altitudes and this is also what the Galileo Probe found when it entered Jupiter's atmosphere.

Jupiter-PIA02865-3.JPGJupiter's clouds - 890 nnmts filter65 visiteTo the North-West (above and to the left) of the dark feature is a small cloud that is bright in the 619-nnmts image but has no contrast at the other wavelengths. This is the signature expected for a thick water cloud. Another feature seen only in the weak-methane ratio is a dark ring near the center of the image.
This feature is probably a counter-clockwise rotating, upwelling core surrounded by a sinking perimeter with diminished cloudiness. The fact that it is seen only in the weak methane ratio indicates the effects of a lower-level circulation that does not penetrated to the upper ammonia cloud level and may be confined to the deeper water cloud.
The opposite behavior is evident in an oval storm that appears dark in 727 and 890 nnmts images, but is absent in the weak 619-nnmts frame. It is located to the South-West of the Great Red Spot. Further to the West - at slightly more Northerly Latitudes - are a series of small spots that are dark at all wavelengths.
These and a myriad of other contrast features at many latitudes reveal much about Jupiter's complicated cloud structure and meteorology.
