I-Telescópio Espacial Hubble iqophe ngephutha isikhathi lapho inkanyezi enomsila C/2025 K1 (ATLAS) iqala ukuhlukana ngemva kokudlula endaweni eseduze kakhulu ku-Sol. Lokhu kubuka kwenzeke phakathi komhla ziyisi-8 nomhla ziyi-10 kuNovemba, 2025, lapho into yasemkhathini isivele iyinqobile i-perihelion ngaphakathi komjikelezo we-Mercúrio. Abacwaningi bahlonze okungenani ama-nuclei amane ahlukene akleliswe esikhundleni somzimba owodwa, obonisa inqubo yokuqala yokuhlakazeka.
Ososayensi basheshe bakhetha inkanyezi enomsila njengethagethi yokushintshanisa phakathi nomkhankaso wokubuka. I-Essa ukukhetha kwethuba kusivumele ukuthi sithwebule into eyivelakancane ngemva nje kokuba inkanyezi enomsila icatshangwe injalo ezinsukwini ezimbalwa ngaphambili. Izithombe zembule ama-cores amaningi anamakhoma awo egesi nothuli, okuqinisekisa ukugqashuka okuqhubekayo.
- Inkanyezi enomsila ibonise ukwakheka kwamakhemikhali okungavamile okunokuqukethwe kwekhabhoni ephansi.
- Ukubuka komhlaba kuqophe ukuguqulwa kokukhanya okungazelelwe kanye nokulibaziseka okuhlobene nokuhlukaniswa.
- Ithimba liphenya indima yeqhwa elisanda kuvezwa nothuli phezulu.
Ukubuka ngengozi kuveza imininingwane yenqubo
Ukuhlukaniswa kwenkanyezi enomsila C/2025 K1 cishe kwaqala cishe izinsuku eziyisishiyagalombili ngaphambi kwezithombe ezingu-Hubble. Ukushisa okukhulu kwelanga nokucindezeleka okushisayo ku-perihelion kube nomthelela ekubhidlikeni kwesakhiwo somongo. Pesquisadores manje hlaziya ukuthi izinto ezidaluliwe zibe nomthelela kanjani ekuziphatheni okwalandela kwento.
Okubhekwayo kuhlanganisa idatha evela ku-Hubble namarekhodi avela kumabonakude asekelwe phansi. Ukuhlanganiswa kwe-Essa kuvumela ukwenza imephu ukuvela kokuhlukana ukusuka ku-perihelion kuya emavikini alandelayo. Ithimba lihlela ukubuka okusha kwe-spectroscopic ukuze liqonde kangcono ukwakheka kwangaphakathi.
Ukwakheka kwamakhemikhali enkanyezi enomsila kubangela isithakazelo
I-C/2025 K1 iveza izici ezingajwayelekile phakathi kwama-comets efwini le-Oort. Sua ubumpofu bekhabhoni buhlukanisa into kwezinye izivakashi kusistimu sonozungezilanga engaphakathi. Ososayensi bafuna ukuqonda ukuthi ingabe lokhu kwakheka kuthinte ngokuqondile ukumelana komnyombo ekushiseni kwelanga.
Ukuhlaziya okusha kwe-spectroscopic nge-Hubble kufanele kwembule okwengeziwe mayelana nezingxenye eziguquguqukayo. Imiphumela ingase ikhanyise izindlela zokusinda nokuqhekeka kuma-comets afanayo. Ucwaningo lufaka isandla olwazini mayelana nokubunjwa kokuqala kwezinto ezisesimisweni sonozungezilanga.
Imiphumela yocwaningo lwezinkanyezi ezinomsila
Ukuthwebula izithombe ngenhlanhla kunikeza ithuba elingandile lokulandela ukuqala kwenqubo yokuhlakazeka. Izingcezu eziningi ziyaqhubeka nokugadwa amathuluzi ahlukene. I-Dados eyengeziwe isiza ukwenza ngcono amamodeli ekuzinzeni kwe-nuclei ye-cometary eduze ne-Sol.
Lokhu kuhlola kuqinisa ukubaluleka kwezinhlelo zokwabiwa kwesikhathi eziguquguqukayo kumabonakude asemkhathini. I-Casos efana nalokhu ibonisa ukuthi izinhloso zamathuba zingakhiqiza kanjani okuzuziwe okunengqondo. Umphakathi wezinkanyezi ulandela ukuvela kwezingcezu ezisele.
Imininingwane yobuchwepheshe yokuthwebula
Ukuchayeka okufushane okuthathu kwemizuzwana engama-20 ngakunye kutholwe ngezinsuku ezilandelanayo. Ukuqondanisa kwe-nuclei kubonakale kucacile ezithombeni ezicutshunguliwe. Ukuhlaziywa kokuqala kwaqinisekisa ukuthi inkanyezi enomsila yayisivele ihlukaniswe yaba izingxenye ezine eziyinhloko.
Ukuba seduze kwesikhashana kwe-perihelion kugqamisa ukuba sengozini kwenkanyezi enomsila kumandla elanga adlulele. Estudos eqhubekayo hlola izinga lokuhlukaniswa phakathi kwezingcezu. Informações iqoqe izingxoxo zikaphethiloli mayelana nokuqina kwezindikimba ezineqhwa emigudwini eguquguqukayo.
Ukuziphendukela kwemvelo kwabonwa ngemva kwezithombe
Amarekhodi ahambisanayo asemhlabeni abonisa ukuhluka komsebenzi wezingcezu kula maviki alandelayo. Ukubambezeleka phakathi kokugqabuka nokukhanya okuphezulu kuphakamisa izinqubo zokukhishwa kwezinto eziyinkimbinkimbi. Pesquisadores qhubeka nokwenza imodeli yalezi zenzakalo ukuze uthole izibikezelo ezinembe kakhudlwana.
Ukuhlakazeka kunikeza ukuqonda okuyingqayizivele ngesakhiwo sangaphakathi senkanyezi enomsila. I-Dados evela ku-Hubble kanye nasezindaweni zokubheka ezisekelwe phansi inothisa isisekelo solwazi mayelana nalezi zinto. Uphenyo luyaqhubeka ngokugxila ezintweni ezibonakalayo namakhemikhali ezihilelekile.
