Stars - basamaniyai cewa haskaka kansu

Ilmin taurari - da kimiyya da hulda da nazarin wani sarari suKe abubuwa. Ya wadãtu da taurari, comets, taurari, taurari, da kuma ba ya shagala da data kasance mamaki, abin da ke faruwa a waje da yanayin duniya, kamar cosmic radiation.

Karatu ilmin taurari, za mu iya samun amsar wannan tambaya "samaniya jikinsu cewa haskaka kansu. Mene ne wannan? ".

The jikin na hasken rana tsarin

Don gano ko akwai sama jikinsu cewa haskaka kansu, ka farko bukatar fahimtar wasu daga cikin wani sarari suKe gawarwakin ne hasken rana tsarin.

Solar System - a duniyar tsarin, a tsakiya a kan star - rãnã, kuma a kusa da 8 taurari: Mercury, Venus, Duniya, Mars, Jupiter, Rubin, Uranus, Neptune. Don a wani sarari suKe jiki kira wani taurãro, shi dole ne hadu da wadannan bukatun:

• Shin rotational motsi a kusa da star.
• Dauki wani nau'i na Sphere, a kudi na isa nauyi.
• Da kewaye ta kewayewa da sauran manyan jikinsu.
• Kada ya zama star.

Taurari ba emit haske, ba za su iya kawai daidai da fall a kan su da rana ta haskoki. Saboda haka ba za mu iya ce cewa duniya - shi ne na sama jikin da haskaka kansu. Wadannan wani sarari suKe jikin su ne taurari.

Sun - da tushen haske a kan Duniya

Samaniya jikinsu cewa haskaka kansu - taurari. Mafi kusa star ga Duniya - shi ne rana. Godiya ta zuwa ga haske da zafin rana, duk rayuwa iya zama da ci gaba. A rana ne cibiyar kusa da taurari, amaryar wata, asteroids, comets, meteorites da cosmic ƙura.

A rana alama m siffar zobe abu, saboda a lokacin da ka kalle shi, ta contours ze sarari. Duk da haka, shi yana mai ɗamfarar jũna da aka hada da gas, da farko tsakanin wanda hydrogen ne ma ba, da kuma sauran abubuwa.

Don ganin cewa Sun yana da wani bayyanannen contours, shi wajibi ne don duba a shi da wani giciye. Sa'an nan za ka lura da cewa shi ya kewaye tuki yanayi, wanda shi ne sau da yawa mafi girma daga diamita. A al'ada haske na Halo ba bayyane saboda haske. Saboda haka, da rãnã yana da wani takamaiman iyakoki da kuma adana a cikin gaseous jihar.

star

Yawan data kasance taurari ne ba a sani ba, su suna located a wata babbar nesa daga Duniya, da yake a bayyane kamar yadda kananan dige. Stars - a wani sarari suKe jiki da haske da kanka. Menene wannan yake nufi?

Stars - glowing duniyoyin hada da iskar gas, wanda ke faruwa thermonuclear halayen. Su surface da daban-daban yawa da kuma zazzabi. A size of taurari ma bambanta da juna, alhãli kuwa sunã mãsu more kuma mafi m taurari. Akwai taurari da suke fi girma fiye da size rãnã, kuma akwai, da kuma mataimakin versa.

Yana da aka hada da gas, zuwa mafi girma har - hydrogen. A kan bãyan tẽkun, da wani babban zazzabi, da hydrogen kwayoyin tsãgewar ƙwãyar cikin biyu kwayoyin halitta. An zarra kunshi wani proton da wani electron. Duk da haka kwayoyin halitta a ƙarƙashin rinjayar high yanayin zafi "release" su electrons, sakamakon wani gas, wanda aka kira - jini. Atom, sauran ba tare da wani electron, da ake kira da kwaya.

Kamar yadda taurari haskaka haske

Star, saboda gravitational karfi, yayi kokarin damfara kanta da kanta, sakamakon a tsakiyar rabo daga gare shi ne karfi da zafin jiki da yistin. Fara faruwa nukiliya halayen, sakamakon samuwar helium da wani sabon core, wanda kunshi biyu protons da biyu neutrons. A sakamakon haka, samuwar wani sabon tsakiya, wani babban adadin makamashi sake. Barbashi-photons tsaya fitar a matsayin haddi makamashi - su ma gudanar da wani haske. Wannan haske yana da karfi da matsa lamba, wanda fitowa daga cibiyar na star, sakamakon wani ma'auni tsakanin matsa lamba da suka samo asali daga tsakiyar da kuma wani gravitational karfi.

Saboda haka, samaniya jikinsu cewa haskaka kansu, wato taurari haskakawa ta hanyar samar da makamashi a nukiliya halayen. Wannan makamashi ne da nufin yaki da wannan gravitational kuma sojojin da watsi da haske. A mafi m wani star ne, da karin makamashi da aka saki, kuma da haske da hasken taurari.

comets

Nisan kafa kunshi kankara gudan jini, cikinsa da gas, ƙura. Da zuciyar shi ba emit haske, amma a lokacin da gabatowa da rana ta core fara narke da barbashi daga turɓãya, datti, gas jefarwa a cikin sarari. Sun samar da wani irin m girgije a kusa da nisan kafa, da ake kira - coma.

Ba za mu iya ce cewa tauraro mai wutsiya - a wani sarari suKe jiki da haskakawa ta kanta. Babban haske cewa emits, aka nuna hasken rana. Da yake daga hasken rana, da nisan kafa ba bayyane haske, kuma kawai na gabatowa da samun hasken rana haskoki, shi ya zama na fili. Nisan kafa da kanta fitarda wani kananan adadin haske saboda coma kwayoyin zarra da kwayoyin da cewa emit photons na samu hasken rana. The "wutsiya" na tauraro mai wutsiya - wani "niƙẽwa kura", wanda aka alama da rana.

meteorites

Ƙarƙashin rinjayar nauyi a kan surface na duniya za su iya fada m cosmic jikinsu, wanda ake kira meteorites. Ba su ƙone a cikin yanayi, da kuma lokacin da wucewa ta hanyar da shi sosai zafi da kuma fara zuwa emit mai haske haske. Irin wannan glowing meteorite kira wani meteor.

A karkashin matsin lamba daga iska iya meteor farfashe a cikin da yawa kananan guda. Ko da yake shi sosai zafi, na ciki na yawanci zauna sanyi, tun a haka short wani lokaci ya da dama, ba zafi sama gaba daya.

Yana iya ƙarasa da cewa na sama jikin da haskaka kansu - taurari. Kawai za su iya yi saboda da tsarin da kuma matakai da ke faruwa a ciki emit haske. Yanaye, zamu iya cewa wani meteorite - a wani sarari suKe jiki da haskakawa ta kanta, amma wannan shi ne zai yiwu ne kawai a lokacin da ta shiga da yanayi.
