Sun - inkwenkwezi ikufutshane Earth

yonke - axakwe puzzle enkulu phezu izazinzulu ezininzi kunye nabaphandi. Kangangexesha umdla elide kwi uMhlaba kunye "abamelwane" yayo musa kuwanika amashumi amawaka abantu. Namhlanje, Noko ke, izazinzulu zobugcisa amanyathelo amaninzi phambili kuphando lwabo uze uphendule umbuzo, kodwa ezinye. Ezinye isithuba mfihlelo inkulu eluntwini.

Umhlaba kunye inkwenkwezi ekufutshane

Umhlaba, njengokuba sisazi, asinguye kuphela lo kwindalo iphela, hayi enkulu ubukhulu (elincinane). Kodwa ngokwenene iyodwa ngenxa yezizathu ezininzi. Phakathi kwabo: ubukho bamanzi neoksijini, osincedayo ukuba siphile umhlaba, iiminerali, umgama unique egqibeleleyo ukusuka elangeni, nokunye. Kaninzi, abantu bafuna ukwazi ukuba kwenzeka ntoni ngaphaya iplanethi yethu.

Le nkwenkwezi ekufutshane Umhlaba kwakhona umdla ukuba abalandeli zesiqhelo. Sun Kudala kwaziwa ngokuba ibhola omkhulu, ekufuphi emhlabeni wethu. Njengoko yaziwa, le nkwenkwezi ikhethekileyo yahlukile zonke ezinye: liphethe plasma eshushu, kwaye sihlale sisondele kungase akukho sidalwa kwindalo iphela.

Iimpawu kweLanga

Izazinzulu ziye zasekwa ukuba ilanga ithatha 99,8% sobunzima le nkqubo. Ukongeza, inkwenkwezi na umthombo wamandla, wabulela apho kukho yonke into esizibonayo. Hayi usanekwa impucuko yamandulo babenqula ilanga. Ayazi kakuhle ukubaluleka kwayo ebomini bethu, baqubuda kuye.

An okunika umdla ubungakanani kwelanga. Izazinzulu bathi ukuba zibekwe ngaphakathi 1300 Planet Earth. Ukongeza, lifana umazibuthe, kutsala ezinye iinkqubo izinto kunye neesathelayithi, kwakunye nothuli cosmic, izijikelezi-langa.

Sun Iimpawu

Kuye kwafunyaniswa ukuba nkwenkwezi ikufutshane Emhlabeni - Sun, ngoko (kunye nezinye izizathu ezininzi), wanikwa ixesha kangaka. Ngenxa yoko, izazinzulu zophando ziye zafumanisa ukuba lithatyathwe ilifu igesi kunye uthuli malunga 4.6 billion kwiminyaka eyadlulayo. Yinto eyaziwayo ukuba ilanga itshiswe ngokucothayo kakhulu, zonke hydrogen ebangel ibekwe macala. Ngaloo ndlela, ufikelela kwindawo incopho iminyaka a billion embalwa. Kusenokwenzeka ukuba le nkwenkwezi elikufutshane Umhlaba ukhamisile kangangokuba chithi iiplanethi yangaphakathi, kuquka ezethu.

Akukho ngaphantsi umdla kukuba ilanga kumhlophe, lo gama bonke abantu kokuba neyayanyaniswa ebomvu okanye naorenji. Ngokufundisisa wezijikelezi, sinako ukubona amatshatshazi plasma inkwenkwezi. Oku kungenxa emasimini eyomeleleyo ngemagnethi. Kukholelwa ukuba umsebenzi utshintsha ngaphezu kweminyaka elishumi elinanye. Xa ncinci, ngoko ke ilanga iphantse amabala. Kubalulekile ukuphawula ukuba ukhanyiso nekhupha umoya amasuntswana ityala aphaphazele ngeenxa isithuba, echaphazela umhlaba ekufuphi. Ukuba intsimi yimagnethi yomhlaba akakho, le miba iza asitshabalalise. Le umqobo engabonakaliyo kusigcina siphila iminyaka million eliqela.

Le nkwenkwezi elikufutshane Earth

imizimba yasezulwini ngezimanga basoloko utsale abantu. Abantu abaninzi banomdla koko inkwenkwezi ikufutshane Earth. Phantse zonke abaphandi bathi ukuba oko ilanga, kodwa kukho nezinye iziphakamiso. Ngokutsho kwabanye abaphengululi, inkwenkwezi uqikelelo - HD subgiant 140283 - yeyona into yokuba abaphandi babefuna elide kangaka. Space Ubudala babephila yiminyaka 13.2 billion ubudala.

Sekunjalo, amaninzi akathandi ukukholelwa ukuba Sun - inkwenkwezi ikufutshane uMhlaba. Enyanisweni kumgama owela ngaphakathi kwama-5 pc (16.308 St. Iminyaka) aman- yezinto isithuba ukuba basondele iplanethi yethu. Xa zizonke, 57 namhlanje eyaziwa iinkqubo nkwenkwezi.

Faka HD 140283

Ngoko ke, ngokutsho izazinzulu ezithile, HD 140283 - inkwenkwezi elikufutshane Umhlaba. Phonononga oko iinkcukacha ngakumbi, bafumana ukuba isithuba ixhoba bobabo iintlobo ezinqabileyo ziinkwenkwezi ezinkulu. Eli qela libandakanya izinto ubunzima yakhe ngaphezu kweenkwenkwezi eziphambili ngokulandelelana, kodwa ngezantsi ezinkulu. Subgiants namhlanje ivela Umhlaba kumgama 186 iminyaka elula. Yenziwe ngoobani kunye iimpawu HD 140283 ukuvumela ukuba bathi kwi yesibini labemi, oko kukuthi kuloo qela, guilabel ndawonye iinkwenkwezi ezininzi mandulo. adalwa ezinjalo Waqhula ngokuba izinto ebonakala ulutsha indalo yethu.

Ngelishwa, omdala kwaye inkwenkwezi ikufutshane Umhlaba ngokucotha obebuza, ukuba ulahlekelwa nokubengezela kwawo. Ukuhlola lakhanya ngakumbi, kwafika nabaphandi ukuya kwisigqibo enkulu ukuba ubudala injongosenzi lidlula lilonke yonke iphela.

Kukho into "uMethusela," elithetha "ixhoba yeBhayibhile." HD 140283 uthi phezu igama elinjalo. Kodwa okwangoku Star icompetition komnye, nenomlanga ebomvu, ngubani isenokuba ubudala yayo efanayo okanye umzalwana omncinane.

Ngenxa yoko, yonke iplanethi yethu iinkwenkwezi ezininzi ezikufuphi ukuba zikhanyise ebusuku ilizwe lethu, kodwa musa ukukhawuleza ukutyhila kuthi iimfihlelo yonke. Sun kwakhona indima ebaluleke kakhulu eyidlalayo.
