The bands were thought to be an expression of Jovian weather, related to winds blowing eastward and westward at different speeds. This animation illustrates a recent discovery by Juno that demonstrates these east-west flows, also known as jet-streams penetrate deep into the planet&#8217;s atmosphere, to a depth of about 1,900 miles (3,000 kilometers). Due to Jupiter&#8217;s rapid rotation (Jupiter&#8217;s day is about 10 hours), these flows extend into the interior parallel to Jupiter&#8217;s axis of rotation, in the form of nested cylinders. Below this layer the flows decay, possibly slowed by Jupiter&#8217;s strong magnetic field. The depth of these flows surprised scientists who estimate the total mass involved in these jet streams to be about 1% of Jupiter&#8217;s mass (Jupiter&#8217;s mass is over 300 times that of Earth). This discovery was revealed by the unprecedented accuracy of Juno&#8217;s measurements of the gravity field.\u00a0Credits: NASA\/JPL-Caltech\/SwRI\/ASI<\/em><\/div>\n<p>Data collected by NASA\u2019s Juno mission to Jupiter indicate that the atmospheric winds of the gas-giant planet run deep into its atmosphere and last longer than similar atmospheric processes found here on Earth. The findings will improve understanding of Jupiter\u2019s interior structure, core mass and, eventually, its origin.<\/p>\n<p>Other Juno science results released today include that the massive cyclones that surround Jupiter\u2019s north and south poles are enduring atmospheric features and unlike anything else encountered in our solar system. The findings are part of a four-article collection on Juno science results being published in the March 8 edition of the journal Nature.<\/p>\n<p style=\"padding-left: 30px;\"><em>\u201cThese astonishing science results are yet another example of Jupiter\u2019s curve balls, and a testimony to the value of exploring the unknown from a new perspective with next-generation instruments.\u00a0 Juno\u2019s unique orbit and evolutionary high-precision radio science and infrared technologies enabled these paradigm-shifting discoveries,\u201d said Scott Bolton, principal investigator of Juno from the Southwest Research Institute, San Antonio. \u201cJuno is only about one third the way through its primary mission, and already we are seeing the beginnings of a new Jupiter.\u201d<\/em><\/p>\n<p>The depth to which the roots of Jupiter\u2019s famous zones and belts extend has been a mystery for decades. Gravity measurements collected by Juno during its close flybys of the planet have now provided an answer.<\/p>\n<p style=\"padding-left: 30px;\"><em>\u201cJuno\u2019s measurement of Jupiter\u2019s gravity field indicates a north-south asymmetry, similar to the asymmetry observed in its zones and belts,\u201d said Luciano Iess, Juno co-investigator from Sapienza University of Rome,\u00a0and lead author on a Nature paper on Jupiter\u2019s gravity field.<\/em><\/p>\n<p>On a gas planet, such an asymmetry can only come from flows deep within the planet; and on Jupiter, the visible eastward and westward jet streams are likewise asymmetric north and south. The deeper the jets, the more mass they contain, leading to a stronger signal expressed in the gravity field. Thus, the magnitude of the asymmetry in gravity determines how deep the jet streams extend.<\/p>\n<figure id=\"attachment_15693\" aria-describedby=\"caption-attachment-15693\" style=\"width: 500px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.jpl.nasa.gov\/spaceimages\/details.php?id=PIA22336\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"15693\" data-permalink=\"https:\/\/hobbyspace.com\/Blog\/?attachment_id=15693\" data-orig-file=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2018\/03\/pia22336-161.jpg\" data-orig-size=\"320,180\" data-comments-opened=\"0\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"Artist&amp;#8217;s view of Jupiter&amp;#8217;s North Pole in Infrared\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;This computer-generated image is based on an infrared image of Jupiter\u2019s north polar region that was acquired on February 2, 2017, by the Jovian Infrared Auroral Mapper (JIRAM) instrument aboard Juno during the spacecraft\u2019s fourth pass over Jupiter.&lt;br \/&gt;\nCredits: NASA\/JPL-Caltech\/SwRI\/ASI\/INAF\/JIRAM.

Now, following the Juno gravity measurements, we know how deep the jets extend and what their structure is beneath the visible clouds. It\u2019s like going from a 2-D picture to a 3-D version in high definition.\u201d<\/em><\/p>\n<p>The result was a surprise for the Juno science team because it indicated that the weather layer of Jupiter was more massive, extending much deeper than previously expected. The Jovian weather layer, from its very top to a depth of 1,900 miles (3,000 kilometers), contains about one percent of Jupiter\u2019s mass (about 3 Earth masses).<\/p>\n<blockquote><p>\u201cBy contrast, Earth\u2019s atmosphere is less than one millionth of the total mass of Earth,\u201d said Kaspi \u201cThe fact that Jupiter has such a massive region rotating in separate east-west bands is definitely a surprise.\u201d<\/p><\/blockquote>\n<p>The finding is important for understanding the nature and possible mechanisms driving these strong jet streams. In addition, the gravity signature of the jets is entangled with the gravity signal of Jupiter\u2019s core.<\/p>\n<p>Another Juno result released today suggests that beneath the weather layer, the planet rotates nearly as a rigid body.<\/p>\n<p style=\"padding-left: 30px;\"><em>\u201cThis is really an amazing result, and future measurements by Juno will help us understand how the transition works between the weather layer and the rigid body below,\u201d said Tristan Guillot, a Juno co-investigator from the Universit\u00e9 C\u00f4te d\u2019Azur, Nice, France, and lead author of the paper on Jupiter\u2019s deep interior. \u201cJuno\u2019s discovery has implications for other worlds in our solar system and beyond. Our results imply that the outer differentially-rotating region should be at least three times deeper in Saturn and shallower in massive giant planets and brown dwarf stars.\u201d<\/em><\/p>\n<p>A truly striking result released in the Nature papers is the beautiful new imagery of Jupiter\u2019s poles captured by Juno\u2019s Jovian Infrared Auroral Mapper (JIRAM) instrument. Imaging in the infrared part of the spectrum, JIRAM captures images of light emerging from deep inside Jupiter equally well, night or day. JIRAM probes the weather layer down to 30 to 45 miles (50 to 70 kilometers) below Jupiter\u2019s cloud tops.<\/p>\n<blockquote><p>\u201cPrior to Juno we did not know what the weather was like near Jupiter\u2019s poles. Now, we have been able to observe the polar weather up-close every two months,\u201d said Alberto Adriani, Juno co-investigator from the Institute for Space Astrophysics and Planetology, Rome, and lead author of the paper. \u201cEach one of the northern cyclones is almost as wide as the distance between Naples, Italy and New York City &#8212; and the southern ones are even larger than that. They have very violent winds, reaching, in some cases, speeds as great as 220 mph (350 kph). Finally, and perhaps most remarkably, they are very close together and enduring. There is nothing else like it that we know of in the solar system.\u201d<\/p><\/blockquote>\n<p>Jupiter\u2019s poles are a stark contrast to the more familiar orange and white belts and zones encircling the planet at lower latitudes. Its north pole is dominated by a central cyclone surrounded by eight circumpolar cyclones with diameters ranging from 2,500 to 2,900 miles (4,000 to 4,600 kilometers) across. Jupiter\u2019s south pole also contains a central cyclone, but it is surrounded by five cyclones with diameters ranging from 3,500 to 4,300 miles (5,600 to 7,000 kilometers) in diameter. Almost all the polar cyclones, at both poles, are so densely packed that their spiral arms come in contact with adjacent cyclones. However, as tightly spaced as the cyclones are, they have remained distinct, with individual morphologies over the seven months of observations detailed in the paper.<\/p>\n<blockquote><p>\u201cThe question is, why do they not merge?\u201d said Adriani. \u201cWe know with Cassini data that Saturn has a single cyclonic vortex at each pole. We are beginning to realize that not all gas giants are created equal.\u201d<\/p><\/blockquote>\n<p>Abstracts of the March 8 Juno papers can be found online:<\/p>\n<ul>\n<li>The measurement of Jupiter\u2019s asymmetric gravity field:\u00a0\u00a0<a href=\"http:\/\/nature.com\/articles\/doi:10.1038\/nature25776\">http:\/\/nature.com\/articles\/doi:10.1038\/nature25776<\/a><\/li>\n<li>Jupiter&#8217;s atmospheric jet-streams extending thousands of kilometers deep:\u00a0\u00a0<a href=\"http:\/\/nature.com\/articles\/doi:10.1038\/nature25793\">http:\/\/nature.com\/articles\/doi:10.1038\/nature25793<\/a><\/li>\n<li>A suppression of differential rotation in Jupiter\u2019s deep interior:\u00a0<a href=\"http:\/\/nature.com\/articles\/doi:10.1038\/nature25775\">http:\/\/nature.com\/articles\/doi:10.1038\/nature25775<\/a><\/li>\n<li>Clusters of Cyclones Encircling Jupiter\u2019s Poles:\u00a0\u00a0<a href=\"http:\/\/nature.com\/articles\/doi:10.1038\/nature25491\">http:\/\/nature.com\/articles\/doi:10.1038\/nature25491<\/a><\/li>\n<\/ul>\n<p>To date, Juno has completed 10 science passes over Jupiter and logged almost 122 million miles (200 million kilometers), since entering Jupiter\u2019s orbit on July 4, 2016.
