New models suggest that shields surrounding numerous storms circling Jupiter's north and south poles may be reason why more than dozen large tempests have circled gas giants extremes without either merging or dissipating in past four years. Juno, NASA Space orbiting Jupiter, has kept its camera on Jupiter's raging storms since it entered planets polar orbit in July 2016. Spacecraft continuously circle solar systems largest and most massive planet, monitoring its stormy poles: eight massive vortexes circling central storm on planet ' north pole, and five swirling around middle storm near its south pole. Storms are massive, many times size and ferocity of Earth's Category 5 hurricanes. One of shorter storm radius measures at about 1 250 miles long, nearly one - third radius of entire Earth and others measure over 2 100 miles in one direction. Their winds whip at under 179 miles per hour, and each is surrounded by shield of vicious anticyclonic winds, spiraling in opposite directions of vortices, like gears pushing against one another in machine. Despite their massive, tempestuous nature, these storms have remained stable since August - not one, on either pole, has dissipated or merged since then. Cheng Li, University of California at Berkeley astronomer, and three colleagues published New Research Monday in PNAS, official journal of National Academy of Sciences, finding that anticyclonic shields are key to storms ' unusual stability. Several theories try to account for idiosyncrasies of Jupiter's vortices. For instance, they tend to move just as cyclones do on Earth. They originate at lower latitudes on Earth, and then they migrate to higher latitudes to Texas, to New Orleans and they all originate near equator, then they go up, Li said in interview. Those hurricanes will die on Earth once they hit and they lose energy source, from warm oceans. But Jupiter has land nor ocean - like Saturn, solar systems other gas giant, Jupiter has no topology to speak of. For its part, ring planet features only one cyclone each of its poles. Models for Saturn's cyclones fail to account for unique polygonal patterns seen on Jupiter. Its systems of vortices arranged geometrically. Pentagon Surrounds South Pole While Octagon Dances Around Its North - For Years They Have Neither Merged Nor Dissipate. To account for these oddities, Li and his colleagues modelled behavior of Jupiter storms to find what variables make difference between stable and unstable polar vortexes. We basically answer question, Why are they stable? We would like to come up with simple explanation, and that simple explanation will involve very few parameters. They describe basic features of atmosphere. We would like to look at what parameters separate space between merging and not Li say.

Peering Beneath Jupiter's Clouds

Cape CANAVERAL, Fla. Jupiter's poles are blanketed geometric clusters of cyclones and its atmosphere is deeper than scientists suspect. These are just some of discoveries reported by four international research teams Wednesday, based on observations by NASA's Juno spacecraft circling Jupiter. One group uncovered constellation of nine cyclones over Jupiter's north pole and six over south pole. Wind speeds exceed 5 hurricane strength in places, reaching 220 mph. Massive storms haven't changed position much merged since observations begin. Team leader Alberto Adriani of Italian National Institute for Astrophysics in Rome was surprised to find such complex structures. Scientists think theyd found something similar to six - side cloud system spinning over Saturn's north pole. Instead, they find octagon - shaped grouping over north pole, with eight cyclones surrounding one in middle, and pentagon - shaped batch over south pole. Each cyclone measures several miles across. Fifth Planet From Our Sun, Gas Giant Jupiter, Is By Far Largest Planet In Our Solar System. Launch in 2011, Juno has been orbiting Jupiter since 2016 peering beneath thick ammonia clouds. It is only second spacecraft to circle planet; Galileo did it from 1995 to 2003. Another of studies in this week's journal Nature finds that Jupiter crisscrossing east - west jet streams actually penetrate of miles beneath visible cloud tops. Refine measurements of Jupiter's uneven gravity field enable Weizmann Institute of Sciences Yohai Kaspi in Rehovot, Israel, and his colleagues to calculate depth of Jet streams at about 3 000 kilometers, or 1 865 miles. Result Is Surprising Because This Indicates That Atmosphere Of Jupiter Is Massive And Extends Much Deeper Than We Previously Expect, Kaspi Said In Email. By better understanding these strong jet streams and gravity field, Kaspi say scientists can better decipher core of Jupiter. Similar situations MAY be occurring on other big gas planets like Saturn, where atmosphere could be even deeper than Jupiter, he say. Jonathan Fortney of University of California, Santa Cruz, who was not involved in research, calls findings extremely robust and says they show high - precision measurements of planets ' gravitational field can be used to answer questions about deep Planetary dynamics. Using similar techniques, Juno could help scientists determine depth of Jupiter's Great Red Spot, colossal swirling storm, Fortney said in companion article in journal. Nasa Jet Propulsion Laboratory researchers Glenn Orton and Fachreddin Tabataba - Vakili, who both take part in cyclone study, say all these new discoveries show Jupiter from new perspective unseen before Juno. We cannot say how many mysteries are left to uncover, they write in email. We are already finding way more results than we ever expect!

Symmetry via Buffer Zones

Nasa's Juno spacecraft is currently mapping Jupiter's magnetic field unprecedented detail. Because field originates in planets ' interior, it can provide insights into what is going on beneath spectacular swirling clouds in planets ' surface layers. In paper in Nature, Moore et Al. 1 analyse data from Juno and that Jupiter's magnetic field is substantially different in planets ' northern and southern hemispheres. Authors consider what might be happening on planet's interior to account for this asymmetry. Read paper: complex dynamo inferred from hemispheric dichotomy of magnetic Field Juno reached Jupiter on 4 July 2016, and it has been gathering data that is transforming our understanding of planets ' deep interior. Previously, we had only broad - brush overview of Jupiter's magnetic Field 2. Juno has brought picture into much sharper focus, allowing revised model of Field to be constructed 3. These advances were possible owing to close approach that Juno made to Jupiter. Spacecraft Flies Only About 4 000 Kilometres Above Jupiter's Surface As It Dives Into Planets ' Gravitational Field Once Every 53 Days 4. Jupiter has strongest planetary magnetic field in Solar System. Ironically, this field is biggest threat to Juno Mission. High - Energy particles from Sun are trapped in field, producing hazard that is dangerous to electronics on which Mission depend. Fortunately, Juno was with protection against this and has survived so far. Magnetic Field Of Jupiter Is Maintained By Electric Currents That Flow In Planets ' Interior. Jupiter is made up mainly of hydrogen and so it is quite surprising that it can conduct electricity at ALL. However, extremely high pressure and density on planet enable hydrogen to enter state known as metallic hydrogen 5. Metallic hydrogen has electrical conductivity similar to that of allowing electric currents to flow. Giant planets take of years to cool down after they are form. Consequently, there is as much heat coming out of Jupiter's interior as is received by planet from Sun. This heat is carried by convection currents, which stir interior and produce swirling clouds and storms such as Great Red Spot that are so beautifully captured by Junos cameras. Convection - driven flows of fluid in interior are slower than surface winds, but they are strong enough to generate Jupiter's magnetic Field by process called dynamo action 6 7. Earth's magnetic field is also produced by convection - driven flow in planets ' interior, but it is planets ' liquid - iron core that allows electric currents to flow. Fields of both Jupiter and Earth are mainly dipolar radial component of field is mostly positive in northern hemisphere and mostly negative in southern hemisphere, as if planet contains bar magnet. Moore and colleagues report that non - dipolar part of Jupiter Field is confined almost entirely to northern hemisphere.
