Ubomi kwi-Super-Earths bunokuba nexesha elingakumbi lokuphuhlisa kunye nokuguquka ngenxa yemagnethi yabo eqhubekayo ebakhusela kwimitha ye-cosmic eyingozi, ngokutsho kophononongo olutsha olupapashwe kwijenali yeSayensi.
I-Space yimekobume eyingozi.Imijelo yamasuntswana ahlawuliweyo asondele kakhulu kwisantya sokukhanya, ekhutshwa kwiinkwenkwezi nakwiminyele ekude, iiplanethi zebhombu.Imitha yemitha ebukhali iqhawula umoya ojikeleze umhlaba kwaye ibangele ukuba iilwandle ezikumphezulu weplanethi zome ngokuhamba kwexesha, zizenze zibekho. ingumqwebedu kwaye ayikwazi ukuxhasa ubomi obunokuhlalwa.Nangona kunjalo, imitha ye-cosmic iyaphambukiswa kude noMhlaba kuba ikhuselwe yimagnethi yayo.
Ngoku, iqela labaphandi elikhokelwa nguLawrence Livermore National Laboratory (LLNL) likholelwa ukuba i-super-Earths - iiplanethi ezinkulu kakhulu kunoMhlaba kodwa zingaphantsi kweNeptune - zinokuba nemimandla yemagnethi. kunabo bajikeleze uMhlaba, oku kuthetha ukuba ubomi kumphezulu wabo buya kuba nexesha elingakumbi lokuphuhlisa nokusinda.
"Nangona kukho iimfuno ezininzi zeplanethi enokuhlalwa kuyo, njengobushushu bomhlaba obukwazi ukuvelisa amanzi angamanzi, ukuba nemagnetosphere enokumelana imitha yelanga ixesha elide kunokubonelela ixesha elide lokuba ubomi buguquke," utshilo uRichard. iphepha.Umbhali okhokelayo uKrause, ingcali yefiziksi eLLNL, uxelele iRejista.
Isitshixo kwintsimi yemagnethi ethe gqolo kukuba nombindi wentsimbi elulwelo oluphola kancinci kancinci. Umhlaba wemagnethi uveliswa ngumaleko wentsimbi etyhidiweyo ejikeleza umbindi wentsimbi eqinileyo. amandla imagnethi.
Nangona kunjalo, iqondo lobushushu lentsimbi enyibilikisiweyo engcwatywe kwiikhilomitha ezingama-2,890 okanye iimayile ezili-1,800 ngaphantsi komhlaba liyabanda.Ekugqibeleni liya kuphola de libe lilungelelene ngokupheleleyo.Ngeli xesha, ijenereyitha yayo yangaphakathi iya kuyeka ukujikeleza kwaye ayisakwazi ukuxhasa imagnethi yomhlaba. imagnethi iya kunyamalala malunga ne-6.2 yeebhiliyoni zeminyaka.
“Xa i-iron iqina, ikhupha amandla kunye nezinto ezikhaphukhaphu kwintsimbi engamanzi, ethi inike umbane ixesha elide.Ngaxa lithile, iqondo lobushushu bombindi wolwelo liyaphola lide linyibilike, nto leyo ethetha ukuba liya kuqalisa ukukhenkceza,” ucacise watsho uKlaus. ubushushu.
Ngamanye amazwi, undoqo we-super-Earth kufuneka uphole kwiqondo lobushushu elisezantsi kakhulu phambi kokuba uqine.Ii-cores zabo ezinkulu zikwathetha ukuba nazo zikhupha ubushushu ngokucothayo kunoMhlaba.
“Siye safumanisa ukuba undoqo omkhulu uya komelela ngama-30% ubude kunondoqo… Umhlaba uphinda kane ukusa kwisithandathu ubunzima boMhlaba],” laqukumbela ngelitshoyo eli phephandaba.
U-Krauss kunye noogxa bakhe bakwazi ukulinganisa iimeko zangaphakathi ze-super-Earths ngokufunda ukuziphatha okunyibilikayo kwentsimbi kuxinzelelo lwe-1,000 gigapascals - phantse kathathu uxinzelelo kwi-core Earth. amaqhekeza entsimbi ukuya kuxinzelelo oluphezulu noluphezulu.
Iimvavanyo zibonise ukuba kwi-1,000 gigapascals, ubushushu obunyibilikayo bentsimbi bumalunga ne-11,000 degrees Celsius. Ngokuthelekisa, uxinzelelo lwangaphakathi loMhlaba lumalunga ne-330 gigapascals, kwaye ubushushu bokunyibilika kombindi walo bumalunga ne-6,000 degrees Celsius.
"Olu luvavanyo lokuqala lokulinganisa ijika lokunyibilika kwentsimbi kuxinzelelo olungaphezulu kwe-290 GPa, okuthetha ukuba ngowokuqala ukunciphisa ubushushu bokunyibilika kwentsimbi phantsi kweemeko eziphambili ze-Super-Earth," uKrause uxelele u-El Reg.
“Izazi ngeenkwenkwezi ziya kusebenzisa ezi ziphumo, kunye nezinto abazijongileyo, ukwenza imephu engcono eyenzekayo ngaphakathi nakwiexoplanets.”®
Ngamafutshane, amasela asebenzela urhulumente waseNyakatho Korea ebe phantse i-400 yezigidi zeedola kwimali yedijithali kunyaka ophelileyo kuhlaselo olulungelelanisiweyo lokuba kunye nokuhlamba imali eninzi kangangoko kunokwenzeka.
Ingxelo ye-Blockchain biz Chainalysis ifumene ukuba abahlaseli balandelela iifemu zotyalo-mali kunye notshintshiselwano lwemali ukuba babe iimali kwaye bazibuyisele kwii-vaults zeNkokheli ezukileyo. Emva koko basebenzisa i-software yokuxuba ukwenza inani elikhulu le-micropayments kwi-wallet entsha, emva koko badibanise kwakhona kwi-wallet. akhawunti entsha kwaye udlulise imali.
I-Bitcoin yayisetyenziselwa inombolo enye ekujoliswe kuyo, kodwa i-ether ngoku yimali ebiwe kakhulu, ibalwa kwi-58 yeepesenti zeemali ezibiweyo, abaphandi bathi. kusenokwenzeka ukuba axabiseke gqitha ngoku kangangokuba abantu abakhathalele ngakumbi.
Ngamafutshane, iSebe leeMoto zaseCalifornia lathi "livavanya kwakhona" imbono yalo malunga nokuba into ebizwa ngokuba yi-Tesla ebizwa ngokuba yi-Full Self-Driving feature iya kufuna ukubeka iliso ngakumbi emva kokuba uchungechunge lweevidiyo lubonise ubungozi beteknoloji.
"Uhlaziyo lwamva nje lwesoftware, iividiyo ezibonisa ukusetyenziswa okuyingozi kobuchwephesha, uphando loluntu yiNational Highway Traffic Administration Administration, kunye negalelo elivela kwezinye iingcali kwintsimi," ngokutsho kweleta ethunyelwe eCalifornia eyenza ukuba iDMV icinge kabini ngoTesla. USen.ULena Gonzalez (i-D-Long Beach), usihlalo weKomiti yezoThutho ye-Senate, okokuqala kuchazwe yiLos Angeles Times.
Ngokungafaniyo nezinye iinkampani zemoto eziziqhubayo ezifana ne-Waymo okanye i-Cruise, i-Tesla ayidingeki ukuba ichaze inani leengozi kwi-DMV yaseCalifornia ngenxa yokuba inokuzimela okuncinci kwaye ifuna ukujongwa komntu.Kodwa oko kunokutshintsha emva kweevidiyo ezifana nabaqhubi kufuneka bathathe Ukuphepha ukujika ngempazamo kubahambi ngeenyawo abawela indlela okanye ukusilela ukubona ilori embindini wendlela iqhubeke ijikeleza.
