Life on super-Earths waxaa laga yaabaa in ay helaan waqti dheeraad ah si ay u horumariyaan oo ay u horumariyaan iyada oo ay ugu wacan tahay goobahooda magnetic joogto ah oo iyaga ka ilaaliya fallaadhaha cosmic waxyeelada leh, sida lagu sheegay daraasad cusub oo lagu daabacay joornaalka Science.
Meel bannaani waa bey'ad khatar ah, durdurrada walxaha la shubay oo aad ugu dhow xawaaraha iftiinka, laga soo saaro xiddigaha iyo galaxyada fog, meerayaasha duqeeya. Shucaaca xooggani wuxuu gooyaa jawiga wuxuuna sababaa in badaha dushiisa meeraha ay qallalaan muddo ka dib, taas oo ka dhigaysa iyaga. oomane ah oo aan awoodin in ay taageeraan nolosha lagu noolaan karo. Si kastaba ha ahaatee, fallaadhaha koofiyadaha ayaa ka leexiya dhulka sababtoo ah waxaa lagu ilaaliyaa goobtiisa magnetka.
Hadda, koox cilmi-baarayaal ah oo uu hoggaaminayo Lawrence Livermore National Laboratory (LLNL) waxay aaminsan yihiin in super-Earths - meerayaasha ka weyn dhulka laakiin ka yar Neptune - waxay sidoo kale yeelan karaan goobo magnet ah. Marka loo eego kuwa dhulka ku xeeran, taasoo la micno ah in nolosha dusha sare ay heli doonto waqti badan oo ay ku horumaraan oo ay ku noolaadaan.
"In kasta oo ay jiraan shuruudo badan oo loogu talagalay meeraha la degi karo, sida heerkulka dusha sare ee awood u leh inuu soo saaro biyo dareere ah, isagoo leh magnetosphere kaas oo u adkeysan kara shucaaca qorraxda muddo dheer waxay siin kartaa waqti dheer oo noloshu ay ku kobcineyso," Richard ayaa yiri. warqad.Qoraaga hogaamiyaha ah Krause, oo ah fiisigiste ka tirsan LLNL, ayaa u sheegay The Register.
Furaha beerta magnetka ee joogtada ah waa isagoo udub dhexaad u ah biraha dareeraha ah kaas oo si tartiib tartiib ah u qaboojiyaha. awood magnetic field.
Si kastaba ha ahaatee, heerkulka birta dhalaalaysa ee lagu aasay meel u jirta 2,890 kiiloomitir ama 1,800 mayl ka hooseeya dhulka dushiisa waa qabow. Ugu danbayntii way qaboobi doontaa ilaa ay si buuxda u dejiso. Halkaa marka ay marayso, koronto-dhaliyaha gudaha ayaa joojin doona wareegta oo ma taageeri karo goobta magnetka. magnetic field wuxuu ku baaba'ayaa qiyaastii 6.2 bilyan sano.
"Markay birta adag tahay, waxay ku sii daysaa tamar iyo walxo fudud birta dareeraha ah, taas oo awood u siinaysa koronto-dhaliyaha muddo dheer.Mararka qaarkood, heerkulka xudunta dareeraha ah waxay ku qaboojiso heerkul dhalaalaysa, taas oo macnaheedu yahay inay bilaabi doonto inay baraf noqoto, "Klaus ayaa sharaxay. Birta gudaha super-Earth waxaa lagu cadaadiyaa cadaadis aad uga sarreeya dhulka, sidoo kale waxay dhalaalisaa meel sare. heerkulka.
Si kale haddii loo dhigo, xudunta super-Earth waxay u baahan tahay inay ku qaboojiso heerkul aad u hooseeya ka hor inta aysan adkeyn. Xubnahooda waaweyn waxay sidoo kale ka dhigan yihiin inay sidoo kale u daadiyaan kulaylka si tartiib tartiib ah marka loo eego Earth.
"Waxaan ogaanay in xudunta super-core ay adkeyn doonto 30% ka dheer inta udub-dhexaadka ah… Dhulku waa afar ilaa lix jeer tirada dhulka,” ayuu wargeysku ku soo gabagabeeyey.
Krauss iyo asxaabtiisu waxay awoodeen inay isku ekaysiiyaan xaaladaha gudaha ee super-Earths iyagoo baranaya habdhaqanka dhalaalka birta ee cadaadiska 1,000 gigapascals - ku dhawaad saddex jeer cadaadiska dhulka xudunta. jajabka birta ilaa cadaadiska sare iyo sare.
Tijaabooyinku waxay muujiyeen in 1,000 gigapascals, heerkulka birta ee dhalaalka ahi uu yahay ilaa 11,000 darajo Celsius. Isbarbardhigga, cadaadiska gudaha ee dhulku waa qiyaastii 330 gigapascals, heerkulka dhalaalka ee xuduntiisuna waa ilaa 6,000 darajo Celsius.
"Tani waa tijaabadii ugu horeysay ee lagu cabbiro qalooca dhalaalka birta ee cadaadiska ka badan 290 GPa, taas oo macnaheedu yahay inay tahay tii ugu horreysay ee lagu xaddido heerkulka dhalaalka birta ee xaaladaha asaasiga ah ee super-Earth," Krause ayaa u sheegay El Reg.
"Astronomers waxay isticmaali doonaan natiijooyinkan, oo ay la socdaan indha-indheyntooda, si ay si wanaagsan u khariidadeeyaan waxa ka socda gudaha iyo exoplanets."®
Isku soo wada duuboo, tuugo u shaqeeya dawladda Kuuriyada Waqooyi ayaa xaday ku dhawaad 400 oo milyan oo doolar oo caddaan ah sannadkii hore weerar abaabulan oo ay ku xadeen oo ay lacag ugu dhaqeen intii suurtagal ah.
Warbixin ay soo saartay Blockchain biz Chainalysis ayaa lagu ogaaday in weeraryahanadu ay la socdaan shirkadaha maalgashiga iyo sarifka lacagaha si ay u xadaan lacagaha oo ay ugu celiyaan khasnadaha hogaamiyaha sharafta leh. Kadibna waxay isticmaalaan software isku dhafan si ay u sameeyaan tiro badan oo lacag-bixinno ah boorsada cusub, ka dibna ku daraan mar kale xisaab cusub iyo wareejinta lacagaha.
Bitcoin ayaa hore u ahayd bartilmaameedka koowaad, laakiin ether hadda waa lacagta ugu badan ee la xado, oo lagu xisaabiyo 58 boqolkiiba lacagaha la xado, cilmi-baarayaashu waxay yiraahdeen. waxaa laga yaabaa inay hadda aad u qiimo badan yihiin oo dadku aad u daneeyaan iyaga.
Marka la soo koobo, Waaxda Gawaadhida Gawaadhida ee California ayaa sheegtay inay "dib-u-eegis ku samaynayso" aragtideeda ku saabsan in Tesla's waxa loogu yeero is-wadidda buuxda ay u baahan tahay kormeer dheeraad ah ka dib markii fiidiyowyo taxane ah ay muujiyeen khatarta tignoolajiyada.
"Cusbooneysiinta software-ka ee ugu dambeysay, fiidiyowyada muujinaya isticmaalka khatarta ah ee tignoolajiyada, baaritaan dadweyne oo ay sameeyeen Maamulka Badbaadada Wadooyinka Wadooyinka Qaranka, iyo talooyin ka yimid khubarada kale ee goobta," sida ku cad warqad loo diray California oo ka dhigtay DMV inay laba jeer ka fekerto Tesla. Sen.Lena Gonzalez (D-Long Beach), oo ah guddoomiyaha guddiga gaadiidka ee Senate-ka, ayaa markii ugu horreysay soo warisay Los Angeles Times.
Si ka duwan shirkadaha kale ee baabuurta iswada sida Waymo ama Cruise, Tesla loogama baahna inay u sheegto tirada shilalka California DMV sababtoo ah waxay leedahay madax-bannaani yar waxayna u baahan tahay kormeerka bini'aadamka. Laakiin taasi waxay bedeli kartaa ka dib fiidiyowyada sida darawallada inay la wareegaan iska ilaali inaad si lama filaan ah ugu leexato dadka lugaynaya ee wadada goynaya ama ku guul daraystay in la ogaado gaadhi xamuul ah oo wadada dhex mara inuu sii dhex wareegayo.
