Kazhinji vanhu vanowanzoshamisika isu tiri vegwara ripi , uye chatinogona kutaura pamusoro peizvi ndechokuti iyi haisi iyo Milky Way pachayo.
Isu tiri vegwara rei?
Iyo nebula kana kuti giraxy yatinobva inyaya yekurukurirano sezvo vazhinji vachisimbisa kuti haisi iyo Milky Way izvo zvechokwadi imwe spiral galaxy panowanikwa solar system uyezve Nyika iripo, iyo nyika yatinogara. Kuti uwane rumwe ruzivo nezve hunhu hwegwara redu renyeredzi, unogona kutarisa chinyorwa ichi maitiro emapoka enyeredzi.
Maererano netsvagiridzo, ine mhomho ye1012 solar masses uye iyo yakakomberedzwa helix. Axis yaro inoonekwa ingangoita 100 light years, yakafanana netriyoni nehafu yemakiromita kana 000 bhiriyoni michina yekudenga. Inofungidzirwa kuti inobata pakati pe9480 ne200 mamiriyoni yenyeredzi dzakasiyana.
Nzira inobva kuZuva ichienda kuaxis yenebula ingangoita 25 light-years, nemamwe mazwi, makumi mashanu nembiri muzana eiyo yakazara astral axis. Gwara renzou rinomiririra chikamu chemuunganidzwa wemapoka enyeredzi makumi mana yakatorwa Local Group, uye ndiyo yechipiri pakukura uye kupenya zvakanyanya mushure meAndromeda (zvisinei, inogona kunge iri hombe, sekuratidzwa kweiyo thesis itsva).
Husiku inoonekwa sechidimbu chisina kujeka chechiedza chichena pedyo nepasi rose renyeredzi. Kusanzwisisika kwegwara redu renzou kunokonzerwa nenyeredzi nezvimwe zvinhu mwaranzi yakananga iri pamusoro pebani renebula, semhepo yemuchadenga. Iyo Milky Way inoratidzika kupenya zvakanyanya mukutarisa kweiyo Sagittarius nzvimbo, sezvo kwairi kuri munzvimbo chaiyo uko musimboti wayo unogona kuwanikwa.
Chokwadi nezvegwara renzou ratiri
Sezvambotaurwa kubva pakutanga, kududzira uye kuratidza kuti nderipi nyeredzi ichokwadi chiri nyore, nokuti nebula yedu pasina mubvunzo Milky Way uye pamusoro pekupa nyika yedu iyo ine nenzira imwechete kune Solar System. Naizvozvo, zvakare zvinonakidza kuziva zvakawanda nezvazvo nzvimbo yePasi muboka renyeredzi, sezvo izvi zvichitibatsira kunzwisisa zviri nani nzvimbo yedu muchadenga.
Mune iyi kurongeka kwemazano, pahusiku hwakawanda hwakanyarara tinokwanisa kusiyanisa mutsetse muchena unoyambuka denga kubva kune rimwe divi kuenda kune rimwe divi, nemhando dzakasiyana-siyana dzenyeredzi, dzimwe dziri diki kana huru. Uyezve, nyeredzi idzodzo chikamu chiduku chevavakidzani vedu. Pakati pedu tose tinoumba Gwara renzou, nemamwe mashoko, gwara redu renzou.
Isu tiri verudzi ripi: Milky Way
El Solar system iri kune imwe yemagumo emhepo, kunyanya makore 28.000 echiedza kubva paaxis uye nekuwedzera, anenge 22.000 anogona kurekodhwa parutivi rumwe norumwe. Izvi zvinoenderana nekudzidza kwe mhando dzemakwara enzou, izvo zvinowedzera ruzivo rwedu rwemaumbirwo azvo uye magadzirirwo azvo.
Hunhu hwegwara redu renzou
Vamwe ve zviri mugwara redu renzou, nde:
1 Saizi
The Milky Way ihombe ine spiral nebula inogona kuva nenyeredzi dzinenge mazana matatu emabhiriyoni, pakati pavo, mambo wedu wenyeredzi, zuva. Nenzira iyi, inogona kuyera makore angangoita 100.000 chiedza paaxis yayo uye ine agglomeration inodarika mabhiriyoni maviri kana ichienzaniswa neyeZuva.
2. Kumonyorora
Pamakore mazana maviri nemakumi maviri nemashanu emamiriyoni Solar system inokwenenzvera pedyo nepakati penebula. Inofamba anenge 270 km. Iyi sangano inodzidzwa maererano ne galaxy uye kuumbwa kwenyeredzi, inova ndima inonakidza yezvenyeredzi.
3. Kupenya
Isu hatigone kusiyanisa axis inopenya sezvo yakasviba yakananga zvinhu, nzvimbo huruva uye inotonhora mhute zvakapindirana, izvo zvisingabvumire kupfuura kwechiedza. Inonyungudika inobata inoshanda gomba dema
4. Mumiririri
La Milky Way ine mufananidzo unooneka we lenzi ine domed. Iyo nucleus inonakidzwa nepakati bhendi ine elliptical profile uye anenge 8.000 light years paaxis. Nyeredzi dziri pakutarisa dzakatsvikinyidzana kupfuura dziri kumagumo. Kuchitenderedza iwe unogona kuona gore rehydrogen, imwe kana imwe nyeredzi uye akasiyana siyana masumbu.
5. Zita
Saizvozvowo, tinogonawo kusangana iyo Milky Way, senge Mugwagwa waSantiago, sezvo uchigona kuona neziso rakashama chidimbu chechiedza chinopinda muchadenga usiku hwose.
Kuwanikwa kwegwara redu renyeredzi
Mu 1610 Galileo, achishandisa teresikopu, akasimbisa tsvakurudzo yaDemocritus, achiverenga nyeredzi dzaakaona mudenga, akavaka mufananidzo weMilky Way sevhiri remuchadenga umo pasi redu rakanyura. Nekudaro, Galileo haana kukwanisa kugadzika chiyero cheiyi nebula. Makore akapfuura muna 1912 hukama huri pakati penguva nekupenya kwenyeredzi hwakaratidzwa akataura Cepheid akasiyana, izvo zvakamubvumira kuverenga nzira dze globular masumbu. Kuti uwane rumwe ruzivo nezve mitumbi yedenga, tarisa chinyorwa ichi pa cumulus makore.
The Local Group
Pamwe chete na Andromeda, Triangle, Makore eMagellan, mapoka enyeredzi maduku uye nebulae, uye mamwe maitiro maduku, vanoumba boka rine chekuita negiravhiti uye iri rinonzi Local Group.
Mhedziso dzekuti tiri vegwara ripi
Kwemamiriyoni emakore takaudzwa kuti solar system inobata galaxy yedu, kureva "Milky Way", Asi zvinyorwa zvitsva zvinoratidza kuti kutanga kwezuva riri muSagittarius dwarf nebula, kuitira kuti payakasvika, Sagittarius yakawedzerwa, yakasundidzirwa parutivi uye yakanyoroveswa neMilky Way mumuenzaniso wekudyiwa kwenyeredzi.
Mepu yedenga
Maererano nezvidzidzo, vatsvakurudzi vakasiyana-siyana vakaita imwe mhando yemepu apo denga raive husiku uye izvi pasina mubvunzo zvakaita kuti tifunge kuti nyeredzi yedu inogona kuva nemavambo ayo mune imwe nebula iri kumedzwa neyedu. Saka, kudzidza kwe nzira yemukaka inova yakakosha pakunzwisisa hukama uhwu.
Mukati mezviri pamusoro apa, kwemazana emakore masayendisiti akaedza kutsanangura chikonzero nei iyo Milky Way inoonekwa nerukova kubva munyika yedu. Saizvozvo, zvinoenderana nemhedzisiro inowanikwa kuburikidza nemepu, Nyika haisi chikamu chayo, asi iyo nebula Sagittarius dwarf, uyo ari kumedzwa.
Maererano nekubvunza kwaitwa nechinangwa icho inobatanidza infrared kutaura munzvimbo, inotungamirirwa neYunivhesiti yeMassachusetts, vatsvakurudzi vari kubvuma zvisingazivikanwi pamusoro pekunyorerana kweMilky Way uye zuva redu rezuva iro rave rakavanzika kwenguva refu.
Kuburikidza nendege dze infrared, vaongorori vakaburitsa mamirioni enyeredzi kuti vazvitungamire mune yambotaurwa M Giant. Nyeredzi idzi dzakawanda muSagittarius galaxy, asi hazviwanzo mugalaxy yedu.
Basa iri risati raitwa, nyanzvi dzenyeredzi vakanga vangowana nyeredzi shoma dzakapararira yeSagittarius Dwarf Nebula. Kunyange kuvapo kwaro hakuna kubatanidzwa kutozosvikira musimboti wouyu musangano wenyeredzi wesatellite waziviswa neboka reBritain ravafambisi vezvikepe zvomuchadenga.
Kurambidzwa kwevanoongorora nyeredzi
El kona panoonekwa Milky Way Inoonekwa mudenga, uye ine masayendisiti anofarira. Kudai nyeredzi yedu yakanga yasikwa muGwara renzou, tingadai tiri panzvimbo yakasvibirira yegwara renzou, nenyeredzi dzakaumbwa pamwe chete kubva kuZuva pakona yakada kufanana neinorongerwa Zuva redu.
Sezvineiwo, sezvakataurwa nemuongorori Edwin, iyo isinganzwisisike kona inoratidza kuti Zuva redu riri kufurirwa neimwe system. Saizvozvowo, vazivi venyeredzi vanoita sevanogutsikana zvishoma mukutaura izvozvo iyo infrared mepu inoita seinogadzirisa chakavanzika uye inotsanangura iyo inoshanda musimboti wesolar system yedu.
Chekupedzisira, zvakakosha kuratidza kuti mhinduro iko zvino kuti nderipi gwara renyeredzi riri nyore kuratidza kubva ipapo tiri pachena kuti hatizi vokwavo Milky Way asi kuno mumwe inomedzwa nayo.
