Ndi mtunda nyenyezi dongosolo Alpha Centauri chiyani? Kodi n'zotheka popita ku Alpha Centauri?

Alpha Centauri - cholinga ndege zouluka ntchito ambiri a mtundu wanyimbo wa yopeka. Ndi nyenyezi yapafupi amatanthauza chithunzi wakumwamba, embodying lodziwika bwino centaur Chiron, malinga ndi Agiriki, ndi mphunzitsi wakale Hercules ndi Achilles.

akatswiri a masiku ano, komanso olemba, zonse akubweranso pa ganizo dongosolo nyenyezi, chifukwa si phungu loyamba la yaitali danga ntchito, komanso mwini zotheka kwa anthu onse padziko lapansi.

kapangidwe

Alpha Centauri nyenyezi dongosolo tichipeza atatu zinthu danga: nyenyezi awiri a dzina ndi zizindikiro zomwezo A ndi B, komanso Proxima Centauri. Pakuti nyenyezi izi wofanana ndi moyandikana wa zigawo ziwiri ndi akumidzi - wachitatu. Proxima basi atsopano. Distance kuti Alpha Centauri ndi zinthu zake zonse ndi za 4.3 kuwala zaka. Nyenyezi pafupi ndi Earth pa nthawi ino. Pa nthawi yomweyo yachangu popita ku Proxima: ife tonse 4,22 zaka kuwala.

achibale dzuwa

Alpha Centauri A ndi B ndi osiyana ndi mnzake osati mtunda dziko lapansi. Iwo mosiyana Proxima m'njira zambiri zofanana ndi dzuwa. Alpha Centaur A kapena Rigel Kentavrus (kutanthauza "mwendo Centaur") owala awiri chigawo. Toliman Ndipo mmene umatchedwanso nyenyezi - nyenyezi yaing'ono yachikasu. Ku Earth izo bwinobwino, chifukwa ali ziro udzakwaniritsidwa. Izi zimapangitsa izo chachinayi pa mndandanda wa mfundo chidwi kwambiri pa thambo usiku. chinthu kukula pafupifupi chikugwirizana komanso dzuwa.

Star Alpha Centaur Mu nyale zathu otsika kulemera (pafupifupi nthawi 0,9 mtengo wa chizindikiro lolingana ya Sun). Zimatanthauza zinthu za ukulu woyamba, ndi mlingo wa luminosity ndi za ziwiri nthawi poyerekeza wa nyenyezi zikuluzikulu za Way wathu chidutswa. Mtunda pakati moyandikana mnzake awiri ndi 23 zakuthambo mayunitsi, ndiko kuti, zili nthawi 23 mopitirira Chrixitu kuposa Lapansi ndi dzuwa. Toliman Toliman A ndi B pamodzi zokhudza malo misa ndi nthawi ya zaka 80.

Kupezeka posachedwapa

Asayansi, monga kale, taika ziyembekezo okwera pa Kupezeka kwa moyo pafupi ndi nyenyezi Alpha Centauri. Mapulaneti ali akuganiza kuti alipo pano, amakhala ngati Lapansi chimodzimodzi monga zigawo zikuluzikulu okha amatikumbutsa dongosolo lathu nyenyezi. Mpaka posachedwapa Komabe, matupi awa dziko anapezeka pafupi nyenyezi. Distance sangathe mwachindunji kusunga mapulaneti. Kupeza umboni kuti kuli Lapansi ngati chinthu anali Zimatheka ndi bwino asanayambe luso.

Pogwiritsa ntchito njira zozungulira-mathamangidwe, asayansi anatha kuona kusinthasintha kakang'ono kwambiri Toliman, akuwuka mchikakamizo cha mphamvu yokoka ya mapulaneti makina izo. Choncho chinapezeka kutsimikizira kuti kuli mmodzi chinthu choterocho mu dongosolo. Kunjenjemerako chifukwa cha dziko anawonetseredwa mu mawonekedwe a kusamutsidwa wake wa masentimita 51 pa mphindi kutsogolo ndiye kumbuyo. Zinthu zakuthambo kusuntha zofanana ngakhale yaikulu adzakhala noticeable kwambiri. Komabe, pa mtunda wa 4.3 kuwala zaka atulukira oscillations n'zosatheka. Komabe, wakhala m'kaundula.

mlongo lapansi

Anapeza dziko makina Alpha Centauri B mu masiku 3.2. Malowa ali pamtunda pafupi kwambiri ndi utali wozungulira nyenyezi kanjira ndi kakhumi zosakwana lolingana chizindikiro khalidwe la Mercury. Unyinji wa chinthu ichi malo pafupi ndi dziko lapansi ndi za 1.1 ndi kulemera Blue dziko. Mu kufanana imeneyi itha: moyandikana, malinga ndi asayansi, kutanthauza kuti chiyambi cha moyo padziko lathuli zosatheka. Mphamvu ya kuwala kufika pamwamba pake heats zochuluka kwambiri za iye.

yapafupi

The chigawo chachitatu cha dongosolo nyenyezi, kupanga kuwundana onse wotchuka - Alpha Centauri C, kapena Proxima Centauri. thupi akunja dzina amatanthauza "nthawi yomweyo". Proxima ndalama kwa anzawo pa mtunda wa zaka okwana 13,000 kuwala. Izi chinthu khumi ndi ukulu, wofiira nyenyezi yaing'ono yaing'ono (za nthawi 7 ang'onoang'ono kuposa Sun) ndi fishy kwambiri. Onani ndi apoyera n'zosatheka. Pakuti Proxima khalidwe "wosakhazikika" amati: nyenyezi amatha mphindi zochepa kusintha mtengo wa luster ake kawiri. Chifukwa cha ichi "khalidwe" mu njira mkati zikuchitika mkati mwa nyenyezi yaing'ono.

malo wapawiri

Proxima wachita kale ankaona kuti chinthu chachitatu cha dongosolo Alpha Centauri, makina awiri a A ndi B zaka pafupifupi 500. Komabe, posachedwapa view ali ikupita patsogolo chofiira nyenyezi yaing'ono alibe poyerekezera ndi iwo, ndipo mogwirizana wa matupi atatu lakumwamba - chodabwitsa zosakhalitsa.

Chifukwa kukaikira kukhala deta limati logwirizana awiri nyenyezi alibe zokwanira mphamvu ya yokoka kukopeka, kwa chete ndi Proxima. Analandira pa chiyambi cha 90s wa atumwi wotsiriza kwa mudziwe nthawi yaitali ayenera kutsimikizira zina. kuzipenya Recent ndi kuwerengetsera asayansi wopezeka yankho sanapatsidwe. Malinga ndi mfundo, Proxima akhoza kukhala m'gulu la magawo atatu ndipo muziyendayenda malo wamba yokoka. Komanso, kanjira kake ayenera kukhala ngati chowulungika elongated, ndi mfundo kutali kwambiri kuchokera pakati - uja amene nyenyezi kuonera pompano.

ntchito

Chirichonse chomwe icho chinali, ndicho Proxima inyamuka kuuluka mu malo oyamba, pamene amakhala alipo. Ulendo kuti Alpha Centauri pa mlingo lino la chitukuko cha sayansi malo akhoza mzaka zoposa 1000. Nthawi imeneyi ndi chabe pang'ono, chifukwa asayansi zimayesetsa kufunafuna mungachite kuchepetsa izo.

Gulu la NASA ofufuza kutsogoleredwa ndi Harold White kusiyana ntchito "Liwiro" chifukwa cha amene ayenera kukhala injini latsopano. Mbali yache adzakhala mphamvu yogonjetsera kuwala kumayendera, kupanga ndege ku Earth kuti nyenyezi yapafupi kudzakhala masabata awiri okha. Chozizwitsa cha luso adzakhala mwaluso kwenikweni ntchito cohesive wa sayansi ongolankhula ndi experimenters. Padakali Komabe, sitima, kugonjetsa kuwala kumayendera - m'tsogolo. Akuti Marc Millis, kamodzi ntchito pa NASA, monga umisiri, anapereka alipo pa mlingo pano patsogolo kuyenda, chikuchitika osati kale kuposa zaka mazana awiri. Kuchepetsa akuti zimatheka ngati kutsegula chidzachitika kuti akhoza kwambiri maganizo alipo za kuyenda danga.

Tsopano Proxima Centauri ndi mabwenzi ake kukhala wofuna cholinga, mumangire posachedwapa. Technology Komabe, nthawi zonse zilibwino, ndi zatsopano zokhudza makhalidwe a dongosolo la zowalitsa - umboni zithunzi. Ngakhale masiku ano, asayansi ambiri zinthu, za 40-50 zapitazo ndipo analibe ndimalota.
