I-Andromeda Nebula yindawo yokuhlala yama-sakramenti

I-Galaxy I-Andromeda Nebula ingenye yamaqoqo amakhulu kunazo zonke ezinkanyezi esiseduze ne-galaxy yethu yasekhaya. Iyingxenye yalokho okuthiwa yiqembu lendawo yezinkanyezi, amalungu alo, ngaphandle kwakhe, yiMilky Way enezinkanyezi ze-galaxy kanye ne-galaxy ye-Triangle (okungenzeka futhi ibe nama-satellites kuze kungabonakali). Eqinisweni, esiseduzane neMilky Way yizinqola ezincane - amaGree Large and Small Magellanic Clouds. I-galaxy ngokwayo iqukethe izinkanyezi eziyizigidi eziyizinkulungwane ezintathu (futhi lokhu kuphindwe kasikhombisa ngaphezu kweyethu), futhi indawo engaphansi kwayo ingaphezu kweminyaka engu-110,000 elula. I-neromeda nebula yimizuzu emibili nesigamu-ukukhanyisa-iminyaka kude nathi, futhi ukuze sifinyelele lapho, isibhamu esiphezulu kunazo zonke singathatha iminyaka eyizigidi ezingu-46. Lokhu okungenani izikhathi eziyisithupha ngaphezu komhlaba okhona. Izibalo ezinzima ngisho nokuzicabanga!

Umlando wokubheka umgogo womakhelwane

Iqoqo elinyene lezinkanyezi esibhakabhakeni libuyiselwe emuva eNkathini Ephakathi. Ngokuyinhloko, kwenye yezincwadi zama-Arabhu, i-Andromeda Nebula ibizwa ngokuthi ifu elincane. Leli qembu lezinkanyezi, elise-Andromeda ye-constellation (eqinisweni, i-nebula futhi enegama layo) lagcinwa yizazi zezinkanyezi amakhulu eminyaka. Kodwa-ke, ngaphandle kwenqubekela phambili enkulu ekuchazeni kwayo. Noma kunjalo, amathuba ochwepheshe avumela abantu ukuba bathathe isinyathelo phambili kulokhu. Ngo-1885, kunomcimbi othakazelisayo - ku-galaxy ye-Neromeda Nebula, i- supernova iqhume , futhi ukunakekelwa kwezinkanyezi emhlabeni wonke kuphendukela kuleli qembu. Yiqiniso, ngokusho kweyodwa inguqulo, yaqhuma esikhathini esidlule, eminyakeni eyizigidi eziningana edlule, nokuthi yini ososayensi abayithathile ekuzalweni kwenkanyezi entsha kuvele nje ukukhanya okuvela ekuqhumeni, okwamanje (noma kunalokho, ngo-1885) kufinyelele eMhlabeni. I-Andromeda Nebula, isithombe sayo esatholwa kuqala ngo-1887, sivela ngaphambi kwezazi zezinkanyezi ngesimo seqoqo elikhulu lezindikimba zokuvunguza. Ukutholakala okumangalisayo kwenziwa ngo-1921 yi-American Vesto Slipher. Ukubala umzila wokuhamba kwe- galaxy, wathola ukuthi i-Andromeda Nebula ngejubane elikhulu ligijima ngqo eMilky Way. Ngokwezibalo zanamuhla zezazi zezinkanyezi, eminyakeni engamabhiliyoni ayi-4 kuyoba khona ukuhlanganiswa kwezinkanyezi ezimbili. Ayibonakali njengokushayisana, kodwa izinkanyezi zamaqoqo amabili ngokuqinisekile zizobhekana nokuhlelwa kabusha okuphawulekayo kanye noshintsho ezindleleni zabo siqu. Ngokuqinisekile, izidumbu eziningi zizophonswa ngaphandle kwemingcele ye-galaxy esanda kumiswa ibe isikhala se-interstellar. Ngokuthakazelisayo, ngo-1993, elinye iqoqo lezinkanyezi litholakala phakathi nendawo ye-Andromeda Nebula. Mhlawumbe kungumzila womunye umlayezo, obanjwe yizigidi ze-Nebula zeminyaka edlule.

Izici ze-Nebula

Ngokomqondo wezinkanyezi ze-astrophysicists zanamuhla, ezindaweni zamagalaxi amaningi okuvunguza kukhona izimbobo ezimnyama eziphezulu. Kunzima ukucubungula ngenxa yesikhwama esikhulu sezinkanyezi ezikhungweni zemiklamo, futhi ngenxa yokungabi khona kwemisebe noma ukukhanya. Noma kunjalo, izimbobo ezimnyama zingatholakala ngokubheka ukuthi zithinta kanjani ezinye izinto. Kuyathakazelisa ukuthi ku-nucleus ye-Andromeda Nebula kukhona ngesikhathi esifanayo ukhetho olunjalo kumabhobho omnyama aphezulu.
