Nws yog lub hnub qub hnub qub ntawm sab qaum teb hemisphere ntawm lub ntuj Tri (lub npe luv Latin rau Triangulum) uas yog ib qho ntawm cov khoom nyiam tshaj plaws rau cov neeg nyiam ua haujlwm tshawb nrhiav.

Nyob saum ntuj

Nyob rau hmo tsaus ntuj, thaum tsis muaj qhov ci ci, peb tuaj yeem ntes nws hauv daim duab ntawm daim duab kom meej meej tsim los ntawm peb lub hnub qub, zoo ib yam li daim duab peb sab elongated. Lawv lub hnub qub loj tau nthuav tawm raws li hauv qab no: 3m thiab ob 4m txhua.

Yog li pom qhov muag tsis pom.

Los ntawm cov hnub qub nyob sib ze, koj tuaj yeem taug kev hauv lub hnub qub kom pom lub hnub qub Triangulum. Andromeda, Perseus, Aries thiab Pisces yuav pab koj nrog qhov no.

From keeb kwm thiab mythology

Lub hnub qub no tau paub txij thaum ub los, tab sis lub npe los ntawm qhov twg tseem tsis tau paub. Muaj cov ntawv sau txog nws hauv Babylonian catalogs thiab cov ntawv sau, uas tau sau tseg nyob ib ncig ntawm 1100 BC.

Cia tham txog cov yam ntxwv ncov

Lub hnub qub daim duab peb sab tsim cov duab uas zoo li tus duab geometric, raws li nws lub npe qhia.

Delineated los ntawm peb lub hnub qub tseem ceeb tshaj plaws hauv lub hnub qub. Cov khoom ci ntsa iab tshaj plaws Alpha, Beta thiab Gamma tsim cov duab peb sab tiag tiag. Lub cev cosmic tseem ceeb tshaj plaws hauv lub hnub qub Triangulum suav nrog cov khoom ci tshaj plaws hauv nws lub hnub qub, beta hu ua Deltotum. Los ntawm lub ntiaj teb mus rau lub hnub qub no, qhov kev ncua deb yog kwv yees li 125 lub teeb xyoo. Qhov thib ob brightest nyob rau hauv no constellation - Alpha - raws li kev faib tawm, belongs rau cov dawb-daj subgiants. Nws tseem yog hu ua sab saum toj ntawm daim duab peb sab, nws yog ob lub hnub qub ntawm ib qho kev sib luag. Qhov kev ncua deb ntawm lub hnub qub yog 64.2 lub teeb xyoo. Gamma, lub hnub qub ci ntsa iab thib peb, yog lub ntsej muag dawb, nyob ntawm qhov deb ntawm 188 lub teeb xyoo ntawm lub ntiaj teb. Delta muaj cov qauv zoo ib yam li Alpha. Nws muaj ob lub dwarfs - daj thiab txiv kab ntxwv. Qhov kev ncua deb ntawm peb ntiaj chaw thiab cov hnub qub no tsawg kawg yog 35 lub teeb xyoo.

kab laug galaxy M33

Lub hnub qub yog pom tau yooj yim thiab muaj nyob rau hauv nws cov ciam teb pom tsawg kawg tsis yog qhov ci tshaj plaws, tab sis ib qho zoo-paub kauv galaxy M33, uas belongs rau hom Sc thiab yog ib feem ntawm pab pawg ntawm cov galaxies hauv zos.

Muaj ntau lub nebulae hauv nws, muaj ntau lub hnub qub ci xiav loj heev thiab cov hnub qub pawg nrog nce ceev ntawm nws qhov chaw. Qhov kev ncua deb ntawm lub hnub mus rau kauv galaxy M33 yog peb lab lub teeb xyoo. Ntau tshaj 110 lub hnub qub sib txawv tau pom nyob rau hauv lub galaxy txog tam sim no.

Cov khoom loj tshaj plaws hauv thaj av saum ntuj no yog Andromeda galaxy, Milky Way thiab Triangulum galaxy, tseem hu ua M33 lossis NGC598.

Cov kauv galaxies loj tshaj plaws no muaj lawv tus kheej pawg ntawm galaxies. Feem ntau ntawm lawv yog txuam nrog "niam" loj gravitational rog. Lub Triangulum Galaxy txaus siab nyob rau qib thib peb (tom qab Andromeda thiab Milky Way) hauv pab pawg hauv zos ntawm galaxies. Nws txoj kab uas hla yog kwv yees li 50-55.6 txhiab lub teeb xyoo.

Lub qhov dub loj loj M33 X-7 tau pom nyob hauv Triangulum galaxy. Qhov loj ntawm lub cev cosmic yog 16 npaug ntau dua li lub hnub. Qhov no yog ib qhov loj tshaj plaws dub qhov, tshwj tsis yog rau qhov supermassive ntawm qhov deb ntawm peb.

Lub hnub qub Triangulum kuj suav nrog lwm cov kab ke galactic, lawv tsis tshua pom kev, thiab lawv qhov loj tsis tshaj lub hnub qub thib kaum. Qhov loj tshaj ntawm lawv yog kauvgalaxy NGC925. Qhov kev ncua deb ntawm peb lub hnub mus rau NGC925 yog 46 lab lub teeb xyoo. Nws nyob deb txaus, tab sis ua tsaug rau lub telescopes muaj hwj chim loj, astronomers kawm sab nrauv thiab cov khoom tshwj xeeb ntawm lub ntiaj teb nyob rau saum ntuj.
