Izuva rudzii renyeredzi?

Kuwedzera kudiwa kwesimba munyika yedu kunoda kusikwa kwezvitsva. Pane maonero matsva paZuva anoda kuriongorora nemeso matsva, senge unlimited source of energy.

Zuva zvino rinopa vanhu simba rinokwanisa kuzadzisa zvose zvavanoda. Iko kushandiswa kweizvi kunowedzera kushanda uye kunoshanda kutenda kuZuva.Asi, chaizvo Zuva inyeredzi rudzii? Pano tinokuudza izvi uye nezvimwe.

zuva noupenyu

Zuva ndiro tsime guru remasimba ose kwatiri, mumuviri kana kuti zvisina kunanga. Zvirimwa nemhuka zvinoda chiedza chezuva kuti zvirarame. Zvirimwa zvinoshandura chiedza chezuva kuva chikafu kuburikidza photosynthesis. Muitiro mumwe chete iwoyo ndiwowo masikirwo akaita nyika yedu, uye zvisikwa zvakawanda zvinotsamira pazvinomera kuti zviwane zvokudya.

Mamirioni amakore apfuura, zvinhu zvinomera nemhuka zvakachinja kuva zvisaririra zvakadai semarasha, oiri, uye gasi. Izvi zvinosanganisira zvinomera nemhuka zvakafa. Simba renyukireya rinogadzirwa panyika yedu rinobva kusimba reZuva rinokonzerawo mhepo dzomuchadenga uye mafungu egungwa. Uye simbi dzinorema dzakaumbwa dzinenge pakati peZuva. Muchokwadi, solar system ndeyechipiri muzvisikwa nekuti chigadzirwa, chakaumbwa pakasikwa Zuva.

Asi Zuva inyeredzi yakaita sei?

Mugwara renzou risingaremekedzi, Zuva rinoita senyeredzi yechinyakare. Zuva nyeredzi yemhando ye spectral G2 uye kupenya kirasi V mune zvemuchadenga terminology.. Izvi zvinoreva kuti inyenyedzi yeyero ine tembiricha ye 5778 madhigirii Fahrenheit. Iyo yepamusoro K1 ine 5780 metres dhayamita.

Hydrogen inoita 74%, inoumbwa chose nechinhu ichocho. Kuti ndikupe pfungwa, inorema 92% yehuwandu hwayo uye ine huwandu hwakaenzana neiyo yenguva dzose helium tank. Iyo helium yemukati ndeye 24,5% nehukuru uye 7% nehuwandu.. Pamusoro pezvo, kune zvidiki zvidiki zvesimbi inorema, senge iron, nickel, uye lead, izvo zvinosara muzvikamu zvesubatomic. Zvimwe zvinhu zvakaita sesilicon, sarufa, magnesium, kabhoni, okisijeni, uye calcium zvakanyorwa sezvimwe zvinhu mune iyi runyorwa.

Zvido zveZuva

Aya ndiwo mamwe eanonyanya kufadza curiosities eZuva:

• Zuva rinoita serisiri madikanwa sezvo riri munzvimbo isina zvarinoreva.
• Pakati peGalaxy inenge 26.000 chiedza makore kubva Panyika. Kuti asvike ikoko, mutambi anofanira kufamba makore angangoita 900 light years. Nebula inosvika 60.000 light-years kure, kumucheto kwemukati-kati kweOrion's spiral arm.
• Zuva rinofamba nekumhanya kwemakiromita 214 pasekondi..
• Kuti tione nzvimbo yacho yose nemaziso edu maduku, taizofanira kufamba chiedza chegore rimwe chete mumakore 1 1.400 oga oga. Izvi zvingatora vafambi makiromita 200.000 120 kana kuti kanenge kaXNUMX kubva paNyika kuenda kuZuva. Milky Way, ine miriyoni imwe chete yenyeredzi.
• Zuva redu rinowira murudzi rweG2 rwenyeredzi miriyoni, 100% idzo dziri dzvuku dzvuku dzakadzikama kupfuura nyeredzi yedu.
• Masikati, Zuva redu rinopofumadza mamwe masimba emudenga nechiedza chayo chakasiyana. Zvakaoma kutarisa zvakananga nekuda kwekupenya kwayo. Zuva rakakurudzira kuongorora uye kuda kuziva mutsika dzese.
• Vanhu vekare vaimuona samwari uye vakavaka zvifananidzo mukukudza kwake.
• Mayunivhesiti makuru uye maobservatories aripo pasi rese. MuEgypt, Girisi neAmerica, pamwe chete neAsia neEast, kune nhamba huru yekucherechedza.
• Kuvapo kwemienzaniso isingaverengeki inonakidza uye yakasarudzika pasi rese inoratidza kunzwisisa uye kuziva chiedza cheZuva uye kupisa semasimba anotsigira hupenyu.

Kune dzimwe nyeredzi dzakaita seZuva here?

Vazivi venyeredzi vanonetseka kuwana nyeredzi dzinoratidza kutaridzika kweZuva senyeredzi iri pakati nepakati. Izvi zvinodaro nekuti Zuva imwenje wakasarudzika wevazivi venyeredzi. Zvishandiso zvemuchadenga dzimwe nguva zvinoshandisa mapatya pakuenzanisa.

Kusvika kweZuva kune zviridzwa zvedu kunoita kuti zviome kushandisa sechiyero. Zvakare, kupenya kwayo kunoita kuti zviome kushandisa sechiyero chekuenzanisa. Kutsvaga nyeredzi dzakafanana neZuva kwakaburitsa mhedzisiro isingaite. Hapana imwe yenyeredzi idzi ichiri kugamuchirwa seshamwari neZuva.

Nyeredzi 18 Scorpion (HD142633) y HIP56984 ivo kuZuva sezvakaita ziso rako kumuviri waro wose. Kune masayendisiti anoti 18 Scopii yakafanana neZuva nenzira dzakawanda, asi zvakasiyana mune zvimwe zvinhu. Semuenzaniso, inosiyana pakuti ine yakawanda yakawanda. Zvakare Iine lithium yakapetwa katatu kupfuura Zuva.

Kubva pakuona kwesainzi, Zuva rinoratidzika risingazivikanwe kubva kumba kwedu. Asi kune mutumbi wekudenga uri kure, ungangoita makore mazana maviri echiedza kubva kuZuva, wakafanana chaizvo neZuva redu muzera, izvo zvinoita kuti ive. munhu akakodzera kutsvaga mapuraneti akafanana nePasi. Kana humbowo huchiwanikwa, mishoni dzemangwana dzekutsvaga mapuraneti aya dzakarongwa. Izvi zvinotungamira kune pfungwa yekukwanisa kutsvaga hupenyu hwekunze.

zera rezuva

Zuva rave nemakore 4.500 bhiriyoni. asi musimboti wayo wakangoshandisa hafu yehydrogen yayo. Ongororo yemakristasi ehibonite idiki pane millimeter yakaratidza zera renyeredzi huru muzuva.

Zvinotora makore anosvika mabhiriyoni gumi, nyeredzi dzakaita seZuva dzinopenya zvakajeka dzisati dzapera. Izvi zvinobatsira kutsanangura chikonzero nei Zuva riri pakati pehupenyu hwaro.

Zuva rinogadzira simba raro sei?

Zuva rinofungidzirwa kuti ibhora regasi rinopisa rinowedzera-shanduka mukati menzvimbo yaro. Zvikurukuru, izvi zvinoreva chikamu chepakati cheZuva, radius yaro kubva kuZuva inenge 0,2 solar radii, zvichiita kuti zviite kupisa zvakanyanya maererano nezvinodiwa nenyeredzi. Muchokwadi, ihombe yeatomu reactor inosvika 15 miriyoni madhigirii.

Zvitatu muzvina zvehuremu hweZuva zvinoumbwa nemaatomu ehydrogen.. Uye nheyo yenyukireya ine hydrogen yakawanda kupfuura chero imwe nzvimbo. Maatomu eheriyamu akajeka anoumbwa nekubatanidza maatomu maviri ehydrogen.

Helium isati yawanikwa paNyika, yakawanikwa muZuva.Zita rechinhu ichi rinobva kuna mwari wechiGiriki Helios, uyo aiva nebasa rokunamata zuva.

Pakupera kwekushandurwa kubva kuhydrogen kuenda kuhelium, chikamu chidiki chekomboni chinoramba chiripo. Iyo 0,7% misa inoshandurwa kuita simba zvinoenderana neEinstein's formula yenyaya.

Zuva rinoshandura ka3.400 nhamba yemapurotoni ari musekondi yega yega kuita nuclei yehelium. Iyi nzira inogadzira nezve 3.860 bhiriyoni watts. Sekondi yoga yoga matani mamiriyoni 582 egasi rehydrogen anogadzirwa.

Iko kushandurwa kwehelium kubva kuzvinhu zvepakutanga kunoda mamiriyoni mashanu ematani ezvigadzirwa. Bhomba renyukireya rinosvika pakati pe5 megatons yesimba. Naizvozvo, inogona kuburitsa avhareji yeanosvika 9 quadrillion megatons esimba.

Sunspots

Iwo magineti minda zvakasikwa kutenderera zuva nemagetsi emagetsi kutenderera kutenderedza zvinhu zvine ionized zvakatenderedza bhora. Sezvo zuva richitenderera uye kugadzira convection, mitsara yemagineti inowanzoyambuka pamusoro pemuviri wako. Kana mitsara yemagineti ikamanikidzwa uye yowedzerwa, izvi zvinokonzeresa dzvinyiriro inoshanduka panzvimbo chaiyo pazuva. Neiyi mitsetse yezuva resimba rinomonereka kuita sinuous figureheads, uye nzvimbo mbiri dzakapatsanurwa nenzvimbo yechitatu isina kwayakarerekera. Izvo zvakashata zvemagineti zviripo mukati mematunhu anotsanangurwa muchinyorwa ichi.

Nzvimbo isina kujeka uye yakasviba kupfuura epiphase inoumbwa, iyo photosphere. Nzvimbo dzakasviba zvakanyanya dzephotosphere dzinowanzonzi Sunspots. Kupenya kunenge kwarinopimwa ndiko 4200 K. Izvi zvakatemwa nekusiyana nekupenya kwe5800 K. Aya mapoinzi Vanowanzoonekwa vari vaviri vaviri kana mumapoka enhengo dzakawanda. Mukuwedzera, ivo vanowanzoonekwa pamwe chete nemufananidzo wakashata. Uye kwemavhiki mashomanana, chiitiko chinopfuurira.

Ndinovimba chinyorwa ichi pamusoro pemhando yenyeredzi iyo Zuva yakave yakakosha kwauri.
