Kodi Way, ndipo kodi iwo?

Amene mukufuna kuyang'ana kumwamba usiku, mwina anaona lonse gulu mwamphamvu yatcheredwa zosiyanasiyana (owala, sadzachitanso amaonekera, buluu, yoyera, etc.) nyenyezi. limodzi ili ndi Way.

Kodi Way? Chimodzi cha zinsinsi wamkulu wa chilengedwe chonse kwagona kuti nyenyezi zambirimbiri si anamwazikana mosintha mu mlengalenga, ndipo yagawidwa nyenyezi. Mu chimodzimodzi momwe anthu okhala mumzinda, kusiya danga pakati pa midzi kanthu.

lathuli ndi mbali ya Way wa Milky Way. Mayina ena a nyenyezi bwino kudziwika: lalikulu Small Magellanic Mitambo, ndi Andromeda Way. Iwo tikhoza kuona ndi apoyera, pamene ena akutali kwambiri padziko lapansi. Ndithu nthawi yaitali analephera kuona ena nyenyezi, kunapezeka kuti ndi m'zaka za m'ma 20.

"Kodi ndi Way?" - funso limeneli asayansi yaitali chidwi. Koma yojambula weniweni m'dera izi zinachitika mu zaka za zana makumi awiri mochedwa, pamene analengedwa ndi anapezerapo Space Telescope "Hubble".

Kukula kwa mlalang'amba wathu ndi yaikulu zedi moti n'zosatheka n'komwe. zaka zikwi zana limodzi Earth adzafunika mtengo kuwala kufika kwake ndi mapeto wina ndi mzake. Pa malo ake lili phata limene nthambi zingapo woterewu mizere wodzazidwa ndi nyenyezi. "Kachulukidwe" imeneyi mutha kuona yekha Ndipotu iwo zili yosowa kwambiri.

Pali mitundu yosiyanasiyana ya nyenyezi. Iwo amasiyana mawonekedwe, kulemera, kukula, komanso zinthu zili. Iwo onse ali ndi mpweya ndi nyenyezi fumbi. Pali mwauzimu, elliptical, osasamba, NW ngati ndi zina nyenyezi.

Kodi Way? m'badwo wawo ndi chiyani? Kodi iwo ntchito? Kodi njira ndi malo? m'badwo wawo ndi pafupifupi wofanana ndi zaka chonse. Akatswiri a sayansi mpaka pano ndi chinsinsi, kodi pachimake pa mlalang'ambawu. Zakhala anapeza kuti ena mtima ndi wokangalika. Izo zinali zodabwitsa, chifukwa mpaka kupezeka, ankaganiza kuti phata ndi limodzi wandiweyani miyandamiyanda ya nyenyezi. Cheza (kuwala ndi wailesi) zingasiyane ena mitima galactic mu miyezi ingapo. Zimenezi zikutanthauza kuti amasule kwakukulu kuchuluka kwa mphamvu (zambiri kuposa mu supernova kung'anima) mu nthawi yochepa.

Mu 1963, chinavumbula zinthu zatsopano kuti ndi nyenyezi woboola pakati maonekedwe Iwo ankatchedwa quasars. luminosity awo, monga kunapezeka wapamwamba kwambiri kuposa luminosity nyenyezi. Ndi zosadabwitsa kuti kuwala kwa quasars zingasiyane.

Mapangidwe nyenyezi - ndi masoka njira ya zamoyo wa chilengedwe chonse, loyenda mchikakamizo cha mphamvu yokoka. The zosiyanasiyana mitundu yosiyanasiyana ya nyenyezi ndi chifukwa zosiyanasiyana zinthu zomwe iwo anabadwa. Psinjika za khamu la nyenyezi ukhoza biliyoni. 3 Zaka. Panthawi imeneyi, mpweya ndi kusinthika mu dongosolo nyenyezi. Ndi mwa psinjika mtambo mpweya anapanga ndi nyenyezi (pa osalimba zina ndi kutentha zokwanira njira maphatikizidwe).

Pang'onopang'ono nkhokwe interstellar mpweya akuchitiridwa zatha, ndi mapangidwe nyenyezi kumakhala kosavuta kwambiri. Pamene zinthu zonse akatha, mwauzimu Way adziwonetsa lenticular, wopangidwa kwathunthu cha nyenyezi wofiira. Mbali imeneyi ndi elliptical nyenyezi amene mpweya chuma anakhala wina biliyoni 15-20. Zaka zapitazo.

Anthu ambiri ali ndi lingaliro la chimene Way aumbike mwa ambiri mafilimu yopeka, ngwazi amene amakonda ulendo expanses wa mlengalenga, pitani mapulaneti osadziwika nyenyezi. Ndipotu, si wakonzedwa m'tsogolo. Ngakhale ngati ife kuyenda pa liwiro la kuwala (amene sakhoza kukhala nthawi yaitali), ndiye kuti Andromeda Way (Way wathu wapafupi) timapeza zaka pokhapokha okwana 2.5 miliyoni. Ngakhale (malinga kuwerengetsera wa zakuthambo) likuyandikira ife ndi zaka biliyoni 4-5, anakumana ndi wathu Milky Way, Izi zidzapangitsa kuti mapangidwe latsopano elliptical Way.
