Andromeda - renyeredzi pedyo hweGwara Way. Kudhumhana hweGwara Way uye Andromeda

Andromeda - renyeredzi, ainziwo M31 uye NGC224. Izvi helical inotungamirwa yaiva kure anenge 780 Pedyo kp (mamiriyoni 2,5 chiedza-makore) kubva Earth.

Andromeda - renyeredzi pedyo hweGwara Way. I zita rokukudza ngano muchindakadzi. Achicherechedza 2006 kwakaita kuti mhedziso kuti kune pamusoro nyeredzi tiririyoni - kanenge kaviri kupfuura mune hweGwara Way, apo vari, pane vanenge 200 -. Mabhiriyoni 400 Masayendisiti anodavira kuti kudhumhana hweGwara Way uye gwara rinonzi Andromeda zvichaitika munenge 3, bhiriyoni 75 makore, uye pakupedzisira hofori elliptical kana dzeraundi renyeredzi chichagadzirirwa. Asi gare gare ichi. First kudzidza, "ngano Princess" sokunge.

The nhamba inoratidza Andromeda. The renyeredzi rine zvitema uye chena mitsetse. Zvinoumba mhete kumativi urwise inopisa anopenya hofori nyeredzi. Dark mitsetse zvitema-pfumbu anosiyanisa zvikuru tikafunga inopenya zvindori uye kuratidza munzvimbo guru gore cocoons kuti nyeredzi inotungamirwa iri ichangotanga. Paakaona mune chinooneka chikamu chakarondedzera kachiedza Andromeda zvakawanda zvakafanana zononoka maoko. Mugore ultraviolet siyana idzodzo izvi akafanana mhete zvivako. Vakanga kare yakawanikwa pedyo NASA teresikopu. Vanodzidza nezvenyeredzi vanodavira kuti zvindori idzi uchapupu inotungamirwa emapoka ari kudhumhana pamwe pedyo anopfuura mamiriyoni 200 apfuura.

The satellites pamusoro Andromeda

Uyewo Gwara Way, Andromeda ane vanoverengeka zvipfupi satellites, 14 iyo kare zvawanikwa. The dzakakurumbira - M32 uye M110. Zvechokwadi, hazvingaiti kuti nyeredzi imwe neimwe renyeredzi dhumhana nemumwe, sezvo daro kukuru pakati pavo. Chokwadi chokuti chete zvichaitika chokwadi, masayendisiti vachiri chaizvo kujeka pfungwa. Asi kare akagadzira zita neramangwana achangozvarwa. Mlekomeda - saka uyo asati aberekwa Rafa renyeredzi masayendisiti.

Kusanzwisisana nyeredzi

Andromeda - renyeredzi, rinosvika 1 tiririyoni nyeredzi (10 ^12), uye hweGwara Way - 1 bhiriyoni (3 x 10 ^11). Zvisinei, mukana kudhumhana miviri yokudenga iri kunyora nezvavo, sezvo pane daro pavo. Somuenzaniso, pedyo nyeredzi kuti Sun Proxima riri chinhambwe 4.2 makore chiedza (4 x 10 ¹³ km), kana 30 miriyoni (3 x 10 ⁷⁾ Sun diameters. Fungidzira kuti nyeredzi yedu - bhora kuti kutamba tafura Tennis. Zvadaro, Proxima Centauri uchaona sezvinoita pizi, riri chinhambwe 1100? Km kubva, uye hweGwara Way anomunzwira makiromita outwards kusvika mamiriyoni 30. Kunyange nyeredzi nechepakati renyeredzi (uye ichi ndimo mukuru wevasungwa wavo) chiri panzvimbo zvikamu zviri 160 mabhiriyoni (1,6 × 10 ^11)? Km. Zvakafanana bhora yetafura tenesi ose 3.2? Km. Naizvozvo, mukana kuti chero nyeredzi maviri dhumhana kana kubatanidzwa nomumwe mapoka enyeredzi, ishoma zvikuru.

Kudhumhana reBlack Pamakomba

Andromeda uye Gwara Way vane nechepakati supermassive maburi matema signSagittarius A (3,6 * ¹⁰ June rezuva vakawanda) uye chinhu mukati sumbu p2 Galactic neerekitironi. Makomba dema zvinoungana imwe nguva pedyo nepakati rekuUnited mapoka enyeredzi, Rwaipfuura orbital simba chenyeredzi, izvo pamusoro nguva achabviswa kuti yepamusoro trajectory. The pamusoro Izvi zvingatora mamiriyoni emakore. Apo makomba vatema tichaswedera chinhambwe rimwe gore chiedza kubva mumwe, vachava emit rinokweva mafungu. Orbital simba achava kunyange simba zvikuru, kusvikira kwemapazi kwapera zvakazara. Kubva pane simulation data, kuitwa muna 2006, Pasi inogona pakutanga inobviswa zvinenge zvikuru muzinda rekuUnited renyeredzi, ipapo utore yemumwe mumakomba vatema uye kumubvisa pachigaro mhiri Mlekomedy.

chisimbiso dzidziso

The gwara rinonzi Andromeda iri kusvika nesu panguva kumhanya anenge 110 makiromita por wechipiri. Up kusvikira 2012 pakanga pasina nzira yokuziva kana kwete kudhumhana kuchaitika. Pedzisai kuti anenge hakudzivisiki, masayendisiti akabatsira neHubble Space Telescope. Pashure club Andromeda kufamba kubva 2002 kusvika 2010, yakanga vakagumisa kuti kudhumhana zvichaitika nemakore anenge mabhiriyoni 4.

Similar mananara zvakapararira munyika pezvakasikwa. Somuenzaniso, zvinofungidzirwa kuti zviri Andromeda rokupedzisira nevanhukadzi pane imwe renyeredzi. Vamwe zvipfupi emapoka akadaro sezvo SagDEG, uye ikozvino kuramba kusangana pamwe hweGwara Way, kutanga chete isangano.

Studies dzinoratidzawo kuti M33, ari Triangulum Galaxy, kana, - rechitatu pakukura uye chinonyanya kwakajeka mumiririri Local Group - ndichakubvunzaiwo kubatanidzwa chiitiko ichi. Ungangove ichava njodzi kupinda muchadenga yakaumbwa pashure kwemapazi chinhu, uye munguva yemberi iri kure - pakupedzisira kubatana. Zvisinei, M33 kudhumhana pamwe hweGwara Way pamberi pedyo Andromeda kana yedu nyika dzose dzinotenderera zuva vachakandwa mhiri Local Group, Kwabviswa.

Njodzi Solar System

Masayendisiti rokuHarvard nharo kuti mashoko kushamwaridzana emapoka kuvimba tangential nokukurumidza of Andromeda. Pachishandiswa Masvomhu, isu akagumisa kuti pane 50% mukana kuti panguva confluence pakati zuva nenyika dzinotenderera pariri achakandwa kune kure katatu kupfuura mamiriro hweGwara Way Centre. Just handizivi sei kuzvibata vari gwara rinonzi Andromeda. Earth, zvakare, iri mungozi. Masayendisiti anoti ane 12% mukana kuti tine zvimwe nguva pashure kudhumhana achawisirwa shure mhiri vaimbova "musha" yedu. Asi chiitiko ichi hachisi kazhinji kubereka kwazvo nemigumisiro pamusoro zuva nenyika dzinotenderera pariri, uye mitumbi yokudenga havazoparadzwi.

Kana isu haabatanidzi yemapuraneti engineering, ipapo nguva kudhumhana emapoka ari yemandorokwati panyika zvikuru uye hazvizorevi kuramba mvura, uye kudai upenyu.

Possible nemishonga

Kana spirals maviri ikashandiswa, hydrogen chipo pamusoro disks dzavo compressed. Rinotanga ndichibvunza inotungamirwa nyeredzi itsva. Somuenzaniso, unogona kuonekwa nenzira kuwirirana renyeredzi NGC 4039, zvimwe aizivikanwa se "antennas". Panguva chiitiko ane kwemapazi Andromeda uye hweGwara Way iri vaidavira kuti gasi kwavo nemotokari kuramba diki. Nyeredzi harizoiti sezvaraiva kukuru, kunyange zvazvo tingangove ari kubuda ari quasar.

Kubatanidza mugumisiro

Renyeredzi akaumba panguva Junction, vatsvakurudzi kare akataura Mlekomeda. The simulation mugumisiro inoratidza kuti kunoguma chinhu ichava ane elliptical chimiro. centre wawo yakaderera arambe achirema nyeredzi kupfuura ano elliptical enyeredzi. Asi zvimwe wo tenderera chimiro. Zvakawanda achavaponesa sei gasi anoramba mukati hweGwara Way uye Andromeda. Munguva pfupi vakasarira mapoka enyeredzi ari Local Group achava batanidza mugomba chete isangano, uye kucharatidza kutanga itsva shanduka Danho.

Facts pamusoro Andromeda

• Andromeda - chikuru renyeredzi mune Local Group. Asi zvimwe kwete kupfuura akakura. Masayendisiti dzinofungidzira kuti hweGwara Way akaita pfungwa zvikuru rima nyaya, uye izvozvo ndizvo zvinoita redu renyeredzi zvikuru akakura.

• Andromeda kubva Earth anotarira zvinoshamisa. Vazhinji kunyange vanokwanisa mufananidzo nayo.
• Andromeda ane gobvu chaizvo Galactic neerekitironi. Kwete chete nyeredzi huru dziri pakati, asi pane imwe supermassive dema buri zvakavigwa core.
• maoko ayo zononoka vari vakamonyanisa somugumisiro rinokweva kusakarongeka pakati maviri pedyo mapoka enyeredzi: M32 uye M110.
• Inside Andromeda akaitira kanenge 450 globular nyeredzi zvemichindwe. Pakati pavo - kumwe gobvu, vanokwanisa kuona.
• Gwara rinonzi Andromeda - chinhu chinonyanya kure kuti kunogona kuonekwawo pamwe chinoabatsira. Unofanira maonero akanaka uye pasipasi kudzvokora.

In mhedziso, isu mazano vaverengi kazhinji kumutsira meso avo azere nyeredzi. Inoramba yakawanda itsva uye asingazivikanwi. Zvimwe vakasununguka nguva kuchengeta pezvakasikwa panguva kwevhiki. Gwara rinonzi Andromeda mudenga - munhu kuona kuti vanofanira zvachose kuona.
