Lori Glaze, motsamaisi oa lefapha la saense la lipolanete la NASA, ntlo-khōlō ea mokhatlo ona Washington, o itse: “Lipolelo tsena tse ncha tse tsoang ho Juno li bula polokelo ea letlotlo la tlhahisoleseding e ncha mabapi le litšobotsi tse hlokomelehang tsa Jupiter. "Pampiri e 'ngoe le e' ngoe e fana ka leseli mabapi le likarolo tse fapaneng tsa ts'ebetso ea sepakapaka sa polanete - mohlala o babatsehang oa kamoo lihlopha tsa rona tsa mahlale tse fapaneng tsa machaba li matlafatsang kutloisiso ea tsamaiso ea rona ea lipolanete."
Juno e kene potolohong ea Jupiter ka 2016. Nakong e 'ngoe le e 'ngoe ea lifofa-sebakeng tse 37 tsa polanete ho fihlela joale, ho na le lisebelisoa tse khethehileng tse shebileng ka tlas'a sebaka sa eona sa maru se ferekaneng.
"Pele, Juno o ile a re makatsa ka maikutlo a hore liketsahalo tse teng sepakapakeng sa Jupiter li ile tsa teba ho feta kamoo ho neng ho lebelletsoe," ho boletse Scott Bolton, mofuputsi ea ka sehloohong oa Juno ho tsoa Southwest Research Institute e San Antonio le sengoli se etelletseng pele sa pampiri ea Journal Science mabapi le botebo ba maqhubu a Jupiter. "Joale, re se re qala ho kopanya likarolo tsena kaofela le ho fumana kutloisiso ea rona ea pele ea hore na moea o motle le o mabifi oa Jupiter o sebetsa joang - ho 3D."
Juno's microwave radiometer (MWR) e lumella bo-ramahlale ba maikemisetso ho nyarela ka tlas'a leru la Jupiter le ho lekola sebopeho sa lifefo tsa eona tse ngata. Sefefo se tsebahalang ka ho fetisisa ho tsena ke anticyclone e tsebahalang e tsejoang ka hore ke Great Red Spot. Ka bophara ho feta Lefatše, crimson vortex ena e khahlile bo-rasaense ho tloha ha e sibolloa hoo e ka bang lilemo tse makholo a mabeli tse fetileng.
Liphetho tse ncha li bontša hore maholiotsoana a futhumala ka holimo, a na le sepakapaka se tlaase, ha a ntse a bata ka tlaase, a ntse a le holimo. Li-anticyclone, tse potolohang ka lehlakoreng le fapaneng, li bata ka holimo empa li futhumala ka tlase.
Liphuputso li boetse li bonts'a lifefo tsena li telele ho feta kamoo ho neng ho lebelletsoe, 'me tse ling li bolelele ba lik'hilomithara tse 60 (100 kilometers) ka tlase ho maru le tse ling, ho kenyeletsoa Great Red Spot, tse fetang 200 miles (350 kilometers).

Bophahamo le boholo ba Letheba le Lefubelu le Leholo li bolela hore boima ba sepakapaka bo ka har'a sefefo bo ka bonoang ke lisebelisoa tse ithutang matla a khoheli a Jupiter. Lifofane tse peli tse haufi tsa Juno tse holim'a sebaka se tsebahalang haholo sa Jupiter li fane ka monyetla oa ho batla tekeno ea matla a khoheli a sefefo le ho tlatsana le liphetho tsa MWR botebong ba eona.
Ha Juno a ntse a tsamaea tlase holim'a sebaka sa maru sa Jupiter hoo e ka bang 130,000 mph (209,000 kph) Juno bo-rasaense ba khonne ho lekanya liphetoho tsa lebelo joalo ka 0.01 millimeter ka motsotsoana ba sebelisa antenna ea NASA's Deep Space Network tracking, ho tloha bohole ba limaele tse fetang limilione tse 400 (650). lik'hilomithara tse limilione).

"Ho nepahala ho hlokahalang ho fumana matla a khoheli a Great Red Spot nakong ea sefofane sa Phupu 2019 hoa makatsa," ho boletse Marzia Parisi, rasaense oa Juno ea tsoang NASA's Jet Propulsion Laboratory e Southern California le sengoli se etelletseng pele sa pampiri ho Journal Science mabapi le matla a khoheli a matla a khoheli.

"Ho khona ho tlatselletsa seo MWR a se fumaneng botebong ba botebo ho re fa kholiseho e kholo ea hore liteko tsa kamoso tsa matla a khoheli ho Jupiter li tla fana ka litholoana tse khahlang ka ho tšoanang."
Mabanta le Libaka
Ho phaella ho maholiotsoana le li-anticyclones, Jupiter e tsejoa ka mabanta le libaka tse ikhethang - lihlopha tse tšoeu le tse khubelu tsa maru tse pota-potileng polanete. Meea e matla ea bochabela-bophirimela e tsamaeang ka mahlakoreng a fapaneng e arola lihlopha. Juno o kile a sibolla hore meea ena, kapa li-jet stream, li fihla botebong ba limaele tse ka bang 2,000 3,200 (lik'hilomithara tse ka bang XNUMX XNUMX). Bafuputsi ba ntse ba leka ho rarolla sephiri sa hore na li-jet streams li theha joang. Lintlha tse bokelletsoeng ke Juno's MWR nakong ea lipalangoang tse ngata li senola leseli le le leng: hore khase ea ammonia ea sepakapaka e ea holimo le tlase ka tatellano e makatsang le melapo ea jet e bonoang.
"Ka ho latela ammonia, re ile ra fumana lisele tsa potoloho likarolong tse ka leboea le tse ka boroa tse tšoanang ka tlhaho le 'lisele tsa Ferrel,' tse laolang boholo ba boemo ba leholimo mona Lefatšeng", ho boletse Keren Duer, seithuti se fumaneng mangolo Setsing sa Weizmann. of Science in Israel le sengoli se ka sehloohong sa pampiri ea Journal Science ka lisele tse kang Ferrel ho Jupiter. "Le hoja Lefatše le na le sele e le 'ngoe ea Ferrel ho pota hemisphere, Jupiter e na le tse robeli - e 'ngoe le e 'ngoe e kholoanyane ka makhetlo a 30."
