Jupiter-PIA23442.jpgOn the Limb...149 visiteCaption NASA Originale:"NASA's Juno spacecraft captured this impressive image revealing a band of swirling clouds in Jupiter's Northern Latitudes during Juno's close fly-by occurred on November, 3, 2019. Small pop-up storms can also be seen rising above the lighter areas of the clouds, most noticeably on the right side of the image.
This view provides scientists with high-resolution details — the spacecraft skimmed approximately 3.200 miles (such as about 5.149,9 Km) above Jupiter's cloud tops at the time it was taken.
Citizen scientist Björn Jónsson created this enhanced color image using data from the JunoCam camera. The picture, as we wrote above, was taken on November, 3, 2019 at 2:13 p.m. PST (5:13 p.m. EST) at a Latitude of about 38° North".MareKromium

Jupiter-PIA23606.jpgThe "Eye" of Jupiter160 visiteCaption NASA Originale:"Swirling in Jupiter's Atmosphere for hundreds of years, the Great Red Spot is captured in this pair of close-up images from Juno's JunoCam Camera. The giant storm churns through Jupiter's Atmosphere, creating the turbulent flows to its West. On the West-side of the Great Red Spot itself, a sliver of red material is being pulled off the periphery. This is a recent, frequent, phenomenon first observed in ground-based data in 2017.
Two images have been mosaicked together by citizen scientist Kevin M. Gill to create this enhanced color composite. When they were taken on Feb. 12, 2019 at 10:24 a.m. PDT (1:24 p.m. EDT) and 10:29 a.m. PDT (1:29 p.m. EDT), Juno was about 43.500 miles (such as about 70.006,464 Km) above Jupiter's cloud tops. Features as small as 31 miles (approx. 49,889 Km) can be resolved in the images, allowing us to see structure in the interior of the Great Red Spot, as well as the fine texture of the white clouds in the South Tropical Zone below".MareKromium

Jupiter-Red_Spot-BJ.jpgJupiter's Great Red Spot from Voyager 1 (Credit: NASA, JPL; Digital processing: Dr Björn Jónsson - IAAA)109 visiteCaption NASA:"It is a hurricane twice the size of the Earth. It has been raging at least as long as telescopes could see it, and shows no signs of slowing. It is Jupiter's Great Red Spot, the largest swirling storm system in the Solar System.
Like most astronomical phenomena, the Great Red Spot was neither predicted nor immediately understood after its discovery. Still today, details of how and why the Great Red Spot changes its shape, size, and color remain mysterious. A better understanding of the weather on Jupiter may help contribute to the better understanding of weather here on Earth.
The above image is a recently completed digital enhancement of an image of Jupiter taken in 1979 by the Voyager 1 Spacecraft as it zoomed by the Solar System's largest planet.
At about 117 AU from Earth, Voyager 1 is currently the most distant human made object in the Universe and expected to leave the entire Solar Heliosheath any time now".MareKromium

Jupiter-Storms.jpgColliding "Spots"57 visiteCaption NASA originale:"Two storms systems larger than Earth are nearly colliding right now on planet Jupiter. No one was sure what would happen, but so far both storms have survived. In the above false-color infrared image taken last week by the Gemini Observatory in Hawaii, the red spots appear white because their cloud tops tower above other clouds. Blue color represents lower clouds than white, while clouds colored red are the deepest. The smaller red spot, sometimes called Red Spot Jr. or just Oval BA, turned red earlier this year for reasons unknown. If both Jovian hurricanes continue to survive, they will surely pass near each other again in a few years since they revolve around Jupiter at different rates. Astronomers will continue to monitor Red Spot Jr. closely, however, to see if it will remain red when it rotates away from the larger Great Red Spot".

Jupiter-Upper_Atmosphere-PIA16837-PCF-LXTT-IPF.jpgInside Jupiter's Atmosphere (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)75 visiteThe Jupiter's "Dark Hot Spot" visible in this image - taken on December, 13 of the AD 2000 by the NASA - Cassini Spacecraft Imaging Science Subsystem (while Cassini was on its way to the Saturnian System) - is, in a manner of speaking, a "window" that opens deep inside into Jupiter's Upper Atmosphere. In fact, all around the Dark Hot Spot, there are Layers of higher Clouds, with shapes and colors that can help us to identify which Layer of the Jovian Amosphere they actually belong to.
For instance, the three small gray-bluish Clouds visible to to the right of the frame, are located in the Jovian Upper Troposphere, or perhaps even higher, into the Jovian Stratosphere. On the other hand, the large Gray Band located under the Dark Hot Spot (inside which can be - really - barely seen a few bizarre-looking dense Cloud Formations), is positioned in the Lower Troposphere of Jupiter. In addition, a high, gauzy orangish Haze seems to cover a large portion of the frame.
This picture (which is an Original NASA - Cassini Spacecraft b/w false-color frame published on the NASA - Planetary Photojournal with the ID n. PIA 16837) has been additionally processed and then re-colorized in Absolute Natural Colors (such as the colors that an average human eye would actually perceive if someone were onboard the NASA - CASSINI Spececraft and then looked outside, towards the Jupiter), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
Note: we apologize to our Readers, but some of the details (i.e.: a so-called "Gyre" and a "Plume") which characterize part of the dense Cloud-Formations located in the Lower Troposphere of Jupiter can ONLY be seen by watching the false-color version of this frame, as edited by NASA, and found in the Planetary Photojournal. If seen through "human eyes", the aformentioned details disappear almost completely (only the Plume, in fact, can be barely spotted, left of center of the gray Clouds-Band).MareKromium

Jupiter-V1-PIA01324_modest.jpgCrescent Jupiter (from Voyager 1)54 visiteCaption NASA originale:"This crescent view of Jupiter was taken by Voyager 1 on March 24, 1979. This image was taken through three 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-V1-PIA01518_modest.jpgThe "Plume"55 visiteCaption NASA originale:"Reconstruction of a plume on Jupiter, photographed on March 1st, 1979".
Nota: in questo frangente per "plume" si intende uno 'sbuffo' di nuvole bianche e vaporose le quali si distinguono nettamente dal resto del paesaggio circostante.
L'espressione "plume", di regola, viene invece impiegata per indicare il 'pennacchio' di fumo che caratterizza i vulcani in fase eruttiva (innumerevoli sono, infatti, le "plumes" che vediamo sul piccolo - ma attivissimo! - Io).

Jupiter-V2-LAFT-PIA01370_modest.jpgLate afternoon on Jupiter...55 visiteCaption NASA originale:"This color composite made from Voyager 2 narrow-angle camera frames shows the Great Red Spot during the late Jovian afternoon. North of the Red Spot lies a curious darker section of the South Equatorial Belt (SEB), the belt in which the Red Spot is located. A bright eruption of material passing from the SEB northward into the diffuse equatorial clouds has been observed on all occasions when this feature passes north of the Red Spot. The remnants of one such eruption are apparent in this photograph".

Jupiter-V2-PIA00343_modest.jpgJupiter in full detail, by Voyager 256 visiteCaption NASA originale:"The colors have been enhanced to bring out detail. Zones of light-colored, ascending clouds alternate with bands of dark, descending clouds. The clouds travel around the planet in alternating eastward and westward belts at speeds of up to 540 Km p/h. Tremendous storms as big as Earthly continents surge around the planet. The Great Red Spot is an enormous anticyclonic storm that drifts along its belt, eventually circling the entire planet".

Jupiter-V2-PIA01527_modest.jpgThe "Red Spot" of Jupiter53 visiteCaption NASA originale:"The region of white clouds now extends from east of the Red Spot and around its northern boundary, preventing small cloud vortices from circling the feature. The disturbed region west of the Red Spot has also changed since the equivalent Voyager 1 image. It shows more small scale structure and cloud vortices being formed out of the wave structures. The picture was taken on July 3, 1979, from about 6 MKM".

Jupiter-WO-PIA01513_modest.jpgWhite Ovals on Jupiter53 visiteCaption NASA originale:"This photo of Jupiter was taken by Voyager 1 on March 1st, 1979, from a distance of 4.300.000 Km. The region shown is just to the southeast of the Great Red Spot. A small section of the spot can be seen at upper left. One of the 40-year-old white ovals in Jupiter's atmosphere can also be seen at middle left, as well as a wealth of other atmospheric features, including the flow lines in and around the ovals.
The smallest details that can be seen in this photo are about 80 Km across".
