Ngaphandle kweziphithiphithi okanye impikiswano, uthungelwano lwesilumkiso lwe-asteroid lwamazwe ngamazwe luvule umsebenzi ukhuselo lweplanethi ukujonga ngokusondeleyo i-interstellar comet 3I / ATLAS (C / 2025 N1). Isaziso, siqhutywa ngesetyhula evela kwiMinor Planet Centre phantsi kwe igunya le-UAI, ihlaba ikhwelo kwiindawo zokuphonononga kwihlabathi jikelele ukuba zithathe inxaxheba kwiphulo elilungelelanisiweyo lokujonga iinkwenkwezi.
Ukunyakaza akuthethi ukuba i-alamu yempembelelo, kodwa ukuthunyelwa kobugcisa ukulinganisa ngokuchanekileyo ngakumbi into ephazamisa imifuziselo eqhelekileyo. Ihambelana nokuhamba kwayo kwe-perihelion kunye nexesha lokungazinzi okukhulu, ngenxa yoko ISpain neYurophu lungelelanisa izibonelelo kunye nokutshintsha kokuqwalaselwa kunye nenethiwekhi iphela.
Iphulo le-IAWN Astrometry: Liza Kwenziwa Ntoni kwaye Nini?
Isetyhula yeMPEC yavula a Iphulo leComet Astrometry ezinikele ngokupheleleyo kwi-3I/ATLAS, ngenjongo yokulinganisa indlela indawo yayo elinganiswa ngayo xa i-coma kunye nomsila unokujika i-centroid ngokumalunga nokukhanya okuphezulu. Ngamanye amazwi, injongo kukuthintela ukukhanya ekulahlekiseni imathematika kunye nokutsala izisombululo ze-orbital.
Isicwangciso solungiselelo, ngomoya weencwadi zokufunda, sibandakanya pre-workshop, ifestile yokubeka iliso yehlabathi, kunye neeseshini zokuphonononga. Imihla ebalulekileyo yile ilandelayo kumaqela aseYurophu kunye nabanye abathathi-nxaxheba:
- 10 ngoNovemba: Iworkshop yobuchwephesha kwi-astrometry ye-comet ephezulu.
- 25 ngoNovemba: intlanganiso yokhabela ngaphandle.
- NgoNovemba 27 ukuya kwi-27 kaJanuwari: uqwalaselo olulungelelanisiweyo lwehlabathi.
- 3 ngoFebruwari: ukuvala kunye nokuhlalutya i-teleconference.
Ngeli xesha lefestile, ukutshayela ngesantya esiphezulu sefotometric kunye ne-astrometric kuya kwenziwa ngeeteleskopu ezisekwe emhlabeni, ukubeka phambili iibhendi ukubona ngcono kunye nokugubungela ixesha elide ukunciphisa izithuba. I-IAWN ibiza ulungelelwaniso olucokisekileyo kunye nokunika ingxelo ngokukhawuleza kwiZiko lePlanethi encinci ukucokisa isisombululo se-3I / ATLAS se-orbital.
Lo msebenzi ukwafuna ukucokisa iinkqubo zonxibelelwano phakathi kwee-arhente kunye namaziko kazwelonke, umsebenzi ophambili ukulungela ukusebenza ukuba i-IAWN igcinele izinto ezibeka imingeni yomlinganiselo wokwenyani.
I-interstellar comet eneempawu ezingaqhelekanga
Ukusukela ekubhaqweni kwayo, i-3I/ATLAS iziphathe ngendlela engalindelekanga: utshintsho kwimophology yomsila, utshintsho olukhawulezayo kunye ne "anticail" ephawulekayo ejoliswe kwiLanga efunyenwe ngeteleskopu kwiZiqithi zaseCanary, eyathi emva koko yanikezela kwindlela eqhelekileyo.
Isetyhula yobugcisa igxininisa ingongoma ephambili: i "iimpawu ezongeziweyo" iikhomethi zinokutshintsha ngokucwangcisiweyo imilinganiselo ye-centroid ngokumalunga nokuqaqamba okusembindini. Iguquliwe: eyona nto siyibona iqaqambe kakhulu isenokungangqinelani nombindi womzimba, into ebalulekileyo ukuba sizama ukunyenyisa umkhondo wento enqumla iSolar System ukuya kwiimilimitha.
Uqikelelo lokuqala, luxhomekeke ekuhlaziyweni ngedatha entsha, lwalatha kwi-high-inertia comet, mhlawumbi ubunzima obukhulu kakhulu kunye neqhezu elibalulekileyo lomkhenkce oguquguqukayo onokuthi uchaphazeleke ngakumbi kwimitha yelanga kufutshane neperihelion. Le meko inokuthi ithande iziqendu zomsebenzi okanye ulwahlulo olutshintsha ukutyhala okungenamxhuzulane.
Ngokwenyani, wonke umfanekiso ochanekileyo kunye nalo lonke ixesha elilungelelaniswe kakuhle libalelwa ekususeni amathandabuzo malunga nokuvela kwakho. I-cometary dynamicsKe, eli phulo ligxininisa iijometri ezingaguqukiyo, izihluzi, kunye neeprothokholi ukuze iikhathalogu zihambelane ngaphandle kokwazisa umkhethe.
Umngcipheko wokwenyani, ukubonakala kunye nendima yeSpain kunye neYurophu
Isikhundla seziko sicacile: ngokutsho kweNASA kunye namaqela okubeka iliso, akukho sisongelo sempembelelo. Uqikelelo lubeka eyona ndlela ikufutshane kuMhlaba jikelele Iiyunithi ezili-1,8 zeenkwenkwezi (malunga ne-270 yezigidi zeekhilomitha), ngelixa i-perihelion ibalwa ukuba isondele 1,4 AU, ngaphaya nje komjikelo kaMars.
Ngokumalunga nokuqwalaselwa, i-comet kufuneka ihlale ifikeleleka kwiiteleskopu ezisekelwe emhlabeni. kude kube ngoSeptemba, emva koko ukusondela kwayo okubonakalayo kwiLanga kuya kwenza ukulandelela kube nzima; iyakubonwa kwakhona ngoDisemba, ngobude obutofotofo bokuqalisa imilinganiselo.
KwiYurophu, umsebenzi uneziseko zodidi lokuqala: ukusuka kwiindawo zokujonga IItary Islands kwizikhululo ezikwiMeditera kunye neAtlantiki eziya kuqinisekisa ukugqunywa kwexesha kunye nokungafuneki. IZiko loLungelelaniso lweZinto zoMhlaba ezikufutshane le ESA isebenza ngokunxuseneyo ne-IAWN ukulungelelanisa iindlela zokunika ingxelo.
I-IAWN, equlunqwe phantsi kwesambrela yeZizwe eziManyeneyo, idibanisa ukufunyanwa, ukucupha kunye ulawulo lolwazi kwizinto ezinokuba yingozi. Eli phulo liza kusebenza njengebhedi yovavanyo lweenkqubo kunye nokusebenzisana phakathi kwee-arhente, iiyunivesithi, kunye nothungelwano lweprobe.
Umxholo: yi-a ukulungiswa kwehlabathi jikelele ngemeko yokwenyani, hayi imeko kaxakeka. Ukuba i-3I/ATLAS's behaviour iyaqhubeka ukuba yi-atypical, i-routines esulungekileyo kwezi veki ziya kusivumela ukuba sisabele kwaye siyimise ngcono indlela yayo ngaphandle kokubhenela kwiimeko eziyintlekele.
Ukuvuselela ukhuseleko lweplanethi ye-3I / ATLAS ishiya umbono olula: linganisa kakuhle Luthintelo. Ngeshedyuli eneenkcukacha, iiprothokholi ekwabelwana ngazo kunye nokubandakanyeka kweendawo zokujonga izinto eSpain nakulo lonke elaseYurophu, lo msebenzi ujolise ekuguquleni i-comet engalindelekanga ibe yinto eneempawu ezintle, ukunciphisa ukungaqiniseki kunye nokucokisa i-comet. amandla okuphendula ngokubambisana.
