Tam sim no, astronomy tau txais kev faib ntawm tag nrho lub ntuj ceeb tsheej rau hauv 88 ntu - pawg hnub qub - nrog cov ciam teb ruaj. Txawm li cas los xij, yav dhau los, cov hnub qub tau raug txhais raws li cov hnub qub sawv tawm saum ntuj, uas tuaj yeem nco qab los ntawm qee cov ntsiab lus. Lub sijhawm sib txawv, lawv tau muab cov npe cuam tshuam nrog cov ntsiab lus tseem ceeb rau tib neeg. Lub hnub qub me me hauv qab Compass yog ib qho ntawm cov "monuments ntawm lub sijhawm."

Yuav ua li cas lub Compass tshwm saum ntuj

Nyob rau hauv lub sijhawm qub, cov cim dab neeg tau hloov mus rau saum ntuj, hauv Hnub Nyoog Tshiab, thaum cov kws tshawb fawb tau tshawb nrhiav lub ntuj nyob rau yav qab teb Hemisphere, lawv sim ua kom cov npe ntawm European huab tais lossis cov ntsiab lus los ntawm lub neej niaj hnub uas tau ntsib. tsim ntawm science thiab technology ntawm lub hnub qub maps. Nyob deb ntawm tag nrho cov txiv hmab txiv ntoo ntawm cov neeg ua haujlwm no tau muaj sia nyob rau hnub no: piv txwv li, lub hnub qub hluav taws xob tshuab tam sim no tsuas yog nco txog keeb kwm kev xav paub. Tab sis cov pab pawg hnub qub txheeb xyuas nyob rau hauv nruab nrab ntawm lub xyoo pua 18th los ntawm ib tug tswv cuabParis Academy, xib fwb ntawm lej thiab astronomer N. Lacaille, muaj hmoo, thiab ntawm lawv cov constellation Compass.

Legends yos rov qab mus rau qub txeeg qub teg, lub hnub qub no tsis muaj, tab sis tsis ncaj nws tseem txuas nrog ib daim duab mythological uas nyob saum ntuj ceeb tsheej ntev. Lub nkoj loj loj Argo, muaj npe tom qab lub nkoj legendary, tau tshwm sim hauv Ptolemy's atlas ntawm xyoo pua 2 AD. e., thiab ib pab pawg ntawm cov hnub qub dim nyob qhov twg Argo mast qee zaum tau piav qhia hauv atlases, xyoo 1754 ntawm daim duab qhia ntawm Lacaille tau txais lub npe Compass ntawm Navigator (hauv Latin - Pyxis Nautica). Ob xyoos tom qab, Lacaille tau faib lub nkoj Argo rau hauv Stern, Kiel thiab Sails (lawv tseem muaj nyob) thiab tau thov kom tso tawm ib lub hnub qub Mast nyob rau hauv qhov chaw ntawm Compass, tab sis keeb kwm tau txiav txim rau lwm yam, khaws cia, txawm hais tias nyob rau hauv ib tug truncated version, tus thawj lub npe. - Compass (Pyxis, abbreviated as Pyx).

Qhov chaw thiab piav qhia ntawm lub hnub qub

Thaj tsam ntawm lub ntuj uas yog Compass yog me me - tsuas yog 221 square degrees xwb. Nrog rau qhov muag liab qab, koj tuaj yeem pom txog ob thiab ib nrab lub hnub qub hauv nws. Tsuas yog yim tus uas ci dua 5m thiab tsuas yog ob lub ci dua 4m. Lub constellation Compass zoo li yuav luag txoj kab ncaj nraim tsim los ntawm peb lub hnub qub ci tshaj plaws - Alpha, Beta thiab Gamma. Nws nyob ib sab ntawm lub loj Hydra, nrog rau cov hnub qub ntawm Sails, Pump thiab Stern.

Nyob rau sab qaum teb Hemisphere Compass tsis tuaj yeem pom nyob txhua qhov chaw. Nyob rau hauv nruab nrab-latitudes, ib feem ntawm lub constellation yog pom nyob rau hauv lub qab ntug heev nyob rau hauv sab qab teb, thaum tag nrho visibilityua tau tsuas yog sab qab teb ntawm 54 ° sab qaum teb latitude. Lub sijhawm zoo rau kev soj ntsuam yog feem ntau nyob rau lub caij ntuj no - txij lub Ib Hlis mus txog Lub Peb Hlis. Nyob rau hauv daim duab, lub constellation Compass tshwm rau lub qhov muag raws li ib tug tawg ntawm cov hnub qub tsis dim.

Ntxhais hnub qub

Alpha Compass yog chav B kub xiav loj heev nrog qhov kub thiab txias tshaj 24,000 K, 845-880 lub teeb xyoo deb. Nws yuav pom tau tias ci dua yog tias cov plua plav interstellar tsis nqus qee qhov ntawm nws cov hluav taws xob. Lub hnub qub no belongs rau lub sij hawm luv luv pulsating variables ntawm Beta Cephei hom. Qhov loj ntawm Alpha Compass yog ntau tshaj 10 npaug, thiab lub luminosity yog 10,000 zaug siab dua lub hnub.

Lub hnub qub tseem ceeb tshaj plaws hauv lub hnub qub yog ob lub T Compass, uas yog nyob rau hauv chav kawm ntawm kev rov ua dua tshiab. Cov kab ke no suav nrog lub ntsej muag dawb thiab lub hnub qub hnub qub. Qhov kawg tshwm sim tau sau npe hauv 2011. Nws yog qhov ua tau tias qhov loj ntawm cov ntses dawb twb nyob ze rau qhov tseem ceeb, tom qab ntawd qhov kev tawg ntawm supernova yuav ua raws. Ntau txhiab lub teeb xyoo deb ntawm peb, T Compass yog ib qho ntawm cov neeg sib tw supernova ze tshaj plaws rau lub Hnub.

Lub hnub qub Compass muaj ntau lub hnub zoo li lub teeb pom kev zoo, nrog rau lub ntsej muag liab, nyob ib puag ncig uas tau tsim muaj exoplanets. Tag nrho cov ntiaj chaw no yog cov roj loj heev, nyob ze ze rau niam txiv lub hnub qub, lossis, hloov pauv, nyob deb dhau. Cov ntiaj chaw uas muaj huab hwm coj sib piv rau lub ntiaj teb tseem tsis tau pom ntawm no.

hnub qub pawg

Part of the sky related torau lub hnub qub no, suav nrog ntau lub hnub qub qhib pawg. Lawv tuaj yeem pom nrog amateur telescope. Xws li, piv txwv li, yog pawg NGC 2658 (nyob ze Alpha Compass) thiab NGC 2627 hauv cheeb tsam ntawm ob lub hnub qub Zeta Compass.

Zoo nkauj heev qhib pawg NGC 2818. Nws nyob rau sab qab teb ntawm lub hnub qub, thiab ntau dua 10,000 xyoo teeb ntawm peb. Cov khoom no yog qhov zoo tshaj plaws nyob rau hauv uas nws muaj ib tug planetary nebula ntawm ib tug txawv txawv zoo li - cov seem ntawm ib tug gaseous plhaub pov rau hauv qhov chaw los ntawm lub hnub qub uas tau tas nws txoj sia. Lub ntiaj teb zoo nkauj nobula tau yees duab nyob rau hauv siab daws teeb meem los ntawm Hubble Space Telescope nyob rau hauv 2008.

Extragalactic Attractions

Los ntawm cov khoom sib sib zog nqus hauv lub hnub qub Compass, ob lub galaxies tuaj yeem nkag mus rau hauv lub tsom iav raj amateur (txoj kab uas hla ntawm daim iav loj yuav tsum yog tsawg kawg 200 hli): lub elliptical NGC 2663 thiab kauv NGC 2613, uas yog pom tau. tilted "ntug" nyob rau hauv kev sib raug zoo rau lub ntiaj teb soj ntsuam. Cov caj npab kauv ntawm NGC 2613 tsuas yog daws tau los ntawm kev pom ntev ntev nrog lub tsom iav muaj zog.

Yog li, lub hnub qub qis Compass - keeb kwm ntawm lub sijhawm ntawm txoj kev loj hlob ntawm kev taug kev nyob rau sab qab teb dej hiav txwv - tsis ci nrog cov khoom zoo nkauj ntawm qhov ci ntsa iab, thiab txhawm rau kom txaus siab rau kev xyiv fab ntawm nws tus kheej saib ntawm ntu no ntuj, tsim nyog tej yam kev mob thiab lub xub ntiag ntawm ib tug telescope yog tsim nyog. Tab sis txawm tias tus kiv cua ntawm astronomy tsis muaj lub sijhawm zoo li no, nws muaj thiab yuav muaj ntau duaCov duab zoo nkauj yog tsim los siv ob qho tib si muaj zog tshaj lij thiab cov cuab yeej nyiam siv.
