A supernova (/ˌsuːp?rˈno?v?/ plural: supernovae /ˌsuːp?rˈno?viː/ los yog supernovas, abbreviations: SN thiab SNe) yog ib tug muaj zog thiab luminous stellar tawg . Qhov kev tshwm sim astronomical no tshwm sim thaum lub sij hawm dhau los evolutionary theem ntawm lub hnub qub loj los yog thaum ib tug dawb dwarf tau ua rau khiav mus. nuclear kev fusion.
Ib yam li ntawd, tib neeg nug, pes tsawg lub foob pob nuclear yog supernova?
Supernovae yog ib qho ntawm qhov muaj zog tshaj plaws tawg hauv qhov, sib npaug rau lub zog hauv 1028 megaton foob pob (ie, ob peb octillion nuclear warheads ).
Qhov thib ob, lub supernova muaj zog npaum li cas? Pom: Feem ntau Muaj zog Supernova Puas Pom. Astronomers tau glimpsed tshaj plaws muaj zog supernova puas tau pom, lub hnub qub nyob rau hauv lub galaxy billions ntawm lub teeb-xyoos deb uas tawg nrog xws li quab yuam nws luv luv ci ze li ntawm 600 billion lub sij hawm ci dua peb lub hnub thiab 20 lub sij hawm ci dua tag nrho cov hnub qub nyob rau hauv Milky Way ua ke.
Raws li txoj cai, supernova tawg yog dab tsi?
Lub teeb ci ntsa iab yog qhov tawg ntawm a hnub qub uas tau mus txog qhov kawg ntawm nws lub neej, txwv tsis pub hu ua a supernova . Supernovae tuaj yeem luv luv outshine tag nrho galaxies thiab radiate ntau zog tshaj peb lub hnub yuav nyob rau hauv tag nrho nws lub neej. Lawv kuj yog qhov tseem ceeb ntawm cov ntsiab lus hnyav hauv lub qab ntuj khwb.
Lub supernova tawg loj npaum li cas?
Cov hnub qub no xaus lawv cov kev hloov pauv hauv cosmic loj tawg lub npe hu ua supernovae . Thaum twg supernovae tawg , lawv jettison teeb meem rau hauv qhov chaw ntawm qee qhov 9,000 txog 25,000 mais (15,000 txog 40,000 kilometers) ib ob.

Puas yog Dolomite muaj kev tawg lossis tawg?
Dolomite tsis tshua pom muaj nyob rau hauv ib puag ncig niaj hnub sedimentary, tab sis dolostones muaj ntau heev hauv cov ntaub ntawv pob zeb. Lub cev muaj zog ntawm Dolomite Chemical Classification Carbonate Diaphaneity Transparent to translucent Cleavage Perfect, rhombohedral, peb cov lus qhia Mohs Hardness 3.5 txog 4
Puas yog cinder cones tawg?
Cinder cones yog hom kab hluav taws xob yooj yim tshaj plaws. Cov tawg tawg tawg tau tshwm sim los ntawm cov roj tau nthuav dav sai thiab khiav tawm los ntawm cov lava molten tsim cinders uas poob rov qab nyob ib ncig ntawm lub qhov cua, tsim lub khob rau qhov siab ntawm 1,200 ko taw. Qhov kawg tawg tawg tau tso ib tug funnel-zoo li tus crater nyob rau sab saum toj ntawm lub khob hliav qab
Puas yog Mt Pinatubo yuav tawg dua?
20 Xyoo Tom Qab Pinatubo: Yuav Ua Li Cas Volcanoes tuaj yeem hloov pauv huab cua. Tom qab ntawd, thaum Lub Rau Hli 15, lub roob hluav taws tau tawg nws sab saum toj hauv qhov thib ob loj tshaj plaws volcanic eruption ntawm lub xyoo pua. Cov roob hluav taws no tsis yog metronomes; lawv nyiam sib txawv ntawm ib lub ntsiab lus. Txawm hais tias peb tsis cia siab tias yuav pom ib zaug ntxiv hauv peb lub neej, nws tsis yog ua tsis tau.'
Dab tsi ua rau tawg tawg?
Nyob rau hauv volcanology, ib qho tawg tawg yog ib qho hluav taws kub tawg ntawm hom kev ua phem tshaj plaws. Xws li eruptions tshwm sim thaum muaj roj txaus tau yaj nyob rau hauv lub siab nyob rau hauv ib tug viscous magma xws li uas tshem tawm lava hnyav froths rau hauv volcanic tshauv thaum siab dheev txo qis ntawm lub qhov cua
Lub supernova tawg li cas?
Muaj teeb meem ntau dhau ua rau lub hnub qub tawg, ua rau lub supernova. Raws li lub hnub qub khiav tawm ntawm cov roj nuclear, qee qhov ntawm nws cov huab cua ntws mus rau hauv nws cov tub ntxhais. Thaum kawg, lub hauv paus tseem hnyav heev uas nws tsis tuaj yeem tiv taus nws tus kheej lub zog gravitational. Cov tub ntxhais hluas tawg, uas ua rau muaj qhov tawg loj heev ntawm supernova
