Ukuqonda Izinkanyezi Nezinkanyezi Ezitholayo
Amaqoqo ezinkanyezi angenye yezindlela ezindala kakhulu abantu abaye baqonda ngazo isibhakabhaka sasebusuku. Esikhathini eside ngaphambi kwama-telescope, amamephu esibhakabhaka anamuhla, noma isayensi ye-astrophysics njengoba siyayazi namuhla, abantu abavela emiphakathini eyahlukene babebuka amaqoqo ezinkanyezi futhi bawaxhumanise namaphethini. Lawa maphethini aziwa ngokuthi amaqoqo ezinkanyezi. Ngokuthakazelisayo, amaqoqo ezinkanyezi awawona nje "izithombe" esibhakabhakeni, kodwa futhi ahlobene nomlando wamasiko, ukuhamba, amakhalenda, kanye nentuthuko yezinkanyezi njengesayensi. Lesi sihloko sixoxa ngencazelo yamaqoqo ezinkanyezi , umsebenzi wawo kanye nomlando wawo, kanye nokuthi ubani "owathola" wona kumongo womlando onengqondo kakhulu.
Ukuqonda Izinkanyezi Zezinkanyezi
Kalula nje, i-constellation yiqembu lezinkanyezi ezibonakala zakha iphethini ethile uma zibukwa eMhlabeni, bese leli phethini linikezwa igama. Amagama e-constellation avame ukubhekisela ezingomeni, ezilwaneni, noma ezintweni zasenganekwaneni, isibonelo, i-Orion (umzingeli), i-Scorpius (ufezela), i-Leo (ingonyama), njalo njalo.
Nokho, kubalulekile ukuqonda ukuthi izinkanyezi eziseqoqweni lezinkanyezi azihlali zisondelene ngokomzimba. Zibonakala zakha iphethini ngoba izikhundla zezinkanyezi zibonakala edomeni. langit dari perspektif pengamat di BumiEqinisweni, inkanyezi ngayinye ikude kakhulu noMhlaba, futhi eziningi azinawo uxhumano lwamandla adonsela phansi.
Ku-astronomy yanamuhla, igama elithi i-constellation linencazelo ehlelekile kakhulu. I-constellation akuyona nje isithombe esicatshangwayo, kodwa kunalokho isifunda esithile sesibhakabhaka. Lokhu kusho ukuthi yonke indilinga yasezulwini ihlukaniswe ngezifunda ezisemthethweni, ngayinye inegama le-constellation, njengamazwe asebalazweni lomhlaba.
Umsebenzi Wezinkanyezi Kubantu
Izinkanyezi zidlale indima ebalulekile emlandweni wesintu, okuhlanganisa:
1. Navigasi dan penunjuk arah
Abahambi ngamatilosi nabahambi basebenzisa i-bintang njenge-“compass yemvelo.” Isibonelo esaziwayo ukusetshenziswa kweqoqo lezinkanyezi i-Ursa Minor (eliqukethe i-Polaris, noma i-North Star) ukuthola indlela eya enyakatho eNyakatho Nenkabazwe.
2. Ikhalenda nezinkathi zonyaka
Ukuphakama nokushona kwezinkanyezi ezithile ngezikhathi ezithile zonyaka kwasiza abantu basendulo ukuba baqaphele izinkathi ezishintshayo. Lokhu kwakubalulekile kwezolimo, emasikweni, nasekuhleleni uhambo.
3. Ukumapha esibhakabhakeni kanye nokuxhumana kwezinkanyezi
Izinkanyezi zenza kube lula ngezazi zezinkanyezi ukubhekisela ezindaweni zezinto zasezulwini. Isibonelo, lapho abantu bethi "nebula e-Orion" noma "iplanethi ebonakalayo e-Taurus," kusiza ukuhlonza indawo evamile.
4. Ifa lamasiko kanye nelezinganekwane
Izinkanyezi eziningi zixhumene nezinganekwane nezinkolelo, ngaleyo ndlela ziba yingxenye yobuntu bendabuko bomphakathi.
Umlando Omfushane Wezinkanyezi: Kusukela Emasikweni Kuya Ku-Astronomy
Izinkanyezi bezilokhu zaziwa izinkulungwane zeminyaka. Imiphakathi ehlukene ibinezinhlobo zayo namagama ayo, isibonelo:
– IMesopotamiya (iBhabhiloni): eyaziwa njengenye yemiphakathi yokuqala ukuhlanganisa amakhathalogi ezinkanyezi nezinkanyezi.
– IGrisi Yasendulo: yandisa futhi yathandwa kakhulu amaqoqo amaningi ezinkanyezi asetshenziswa kakhulu ezinkanyezini zaseNtshonalanga.
– IShayina: inesimiso sezinkanyezi kanye “nezigodlo zasezulwini” (i-asterism) esihlukile emasikweni amaGreki.
– Isi-Arabhu: Izazi zezinkanyezi zama-Arabhu zenze igalelo elikhulu ekuhumusheni, ekuthuthukiseni nasekuqambeni izinkanyezi eziningi; amagama amaningi ezinkanyezi asetshenziswa namuhla asuselwa kusi-Arabhu (isib., i-Aldebaran, i-Betelgeuse, i-Rigel).
– IPolynesia kanye neqoqo leziqhingi zase-Indonesia: nazo zinamasiko okuzulazula ngezinkanyezi; ezindaweni ezahlukene zase-Indonesia, amaqoqo athile ezinkanyezi aziwa ngamagama endawo ahlobene nemijikelezo yokutshala kanye namasiko.
Lokhu kubonisa ukuthi izinkanyezi azizange “zitholwe” ngumuntu oyedwa kuphela, kodwa kunalokho umphumela ohlangene wokubonwa kwesikhathi eside kuzo zonke izizukulwane.
Ubani Owathola Izinkanyezi Eziqoshwe Ezinkanyezini?
Umbuzo wokuthi ubani “owasungula” amaqoqo ezinkanyezi uvame ukuvela, kodwa impendulo idinga ukucaciswa. Amaqoqo ezinkanyezi awadalwanga ngumsunguli oyedwa, njengocingo noma ugesi. Amaqoqo ezinkanyezi akhule emasikweni ahlukahlukene amasiko. Noma kunjalo, izibalo eziningana nezikhungo ziye zaba nomthelela omkhulu ekwenzeni amaqoqo ezinkanyezi abe sezingeni elifanayo, ikakhulukazi emasikweni aseNtshonalanga nawanamuhla ezinkanyezi.
1. UPtolemaios (uKlaudius Ptolemy) kanye nezinkanyezi zezinkanyezi ezingu-48 zakudala
Isibalo esivame ukuhlotshaniswa “namaqoqo ezinkanyezi” emlandweni wezinkanyezi zaseNtshonalanga nguClaudius Ptolemy (cishe ngekhulu lesi-2 CE), isazi sezinkanyezi nesazi sezibalo esasihlala e-Alexandria (eGibhithe laseRoma). Emsebenzini wakhe odumile, i-Almagest, uPtolemy waqoqa ikhathalogi yezinkanyezi eyayihlanganisa amaqoqo ezinkanyezi angu-48. Lolu hlu lwalungeyona “into eqanjwe nguPtolemy” ngokuphelele—iningi lalo livela emasikweni amadala aseGrisi—kodwa umsebenzi wakhe waba yinkomba eyinhloko amakhulu eminyaka eYurophu naseMpumalanga Ephakathi, futhi ekugcineni wathonya izinkanyezi zanamuhla.
Ngenxa yethonya elikhulu lika-Almagest, uPtolemy uvame ukubhekwa njengomuntu “owasungula” noma “owazuza njengefa” amaqoqo ezinkanyezi akudala aziwa kabanzi.
2. UJohann Bayer kanye namamephu esibhakabhaka asekuqaleni kwesimanje
Ngekhulu le-17, isazi sezinkanyezi saseJalimane uJohann Bayer (1572–1625) washicilela incwadi yezinkanyezi enesihloko esithi Uranometria (1603). Wasiza ekulinganiseni indlela izinkanyezi ezingaphakathi kwezinkanyezi ezaziqanjwa ngayo kusetshenziswa izinhlamvu zesiGreki (isib. u-Alpha Centauri, u-Beta Orionis, njalo njalo). Nakuba uBayer engazange athole izinkanyezi, iminikelo yakhe yayibalulekile ngoba yenza ukumepha isibhakabhaka kube ngokuhlelekile.
3. Inkathi Yokuhlola: Izinkanyezi Esibhakabhakeni SaseNingizimu
Lapho abantu baseYurophu beqala ukuhlola iNingizimu Yenkabazwe ngekhulu le-16 nele-17, babona izindawo zesibhakabhaka ezingabonakali eYurophu. Lokhu kwaveza amaqoqo amaningi amasha ezinkanyezi, ikakhulukazi esibhakabhakeni esiseningizimu. Izibalo ezibalulekile zifaka:
– UPetrus Plancius (1552–1622): wethula izinkanyezi eziningana ezintsha eziphefumulelwe yizilwane nezinto, ezivame ukusetshenziswa kumamephu esibhakabhakeni.
– UFrederick de Houtman (1571–1627): wasiza ekucebiseni ikhathalogu yezinkanyezi esibhakabhakeni saseningizimu.
– UNicolas-Louis de Lacaille (1713–1762): Isazi sezinkanyezi saseFrance esadala inqwaba yezinkanyezi ezintsha, eziningi zazo zisekelwe ezintweni zesayensi (isib. iTelescopium, iMicroscopium), futhi sathuthukisa ukumepha kwesibhakabhaka saseningizimu.
Babengebona “abatholi bezinkanyezi,” kodwa babengabantu abadali bezincazelo zezinkanyezi namamephu ezindawo zesibhakabhaka ezazingabhalwanga kahle ngaphambilini emasikweni aseYurophu.
4. I-International Astronomical Union (IAU): Ukumiswa Kwezindikimba Ezisemthethweni Ezingu-88
Dalam astronomi modern, pihak yang paling berwenang terkait konstelasi adalah International Astronomical Union (IAU) , organisasi astronomi internasional yang didirikan tahun 1919. Pada tahun 1920-an hingga 1930-an, IAU menetapkan 88 konstelasi resmi beserta batas-batasnya di langit. Salah satu tokoh penting dalam proses pembakuan batas konstelasi adalah astronom Belgia Eugène Delporte , yang membantu merumuskan batas resmi konstelasi yang masih dipakai hingga sekarang.
Ngakho-ke, uma umbuzo othi "umtholi" uhunyushwa njengeqembu elasungula ngokusemthethweni amaqoqo ezinkanyezi ngokwesayensi yanamuhla, khona-ke impendulo ikhomba ku-IAU (kanye nezibalo ezihilelekile). Kodwa-ke, uma "umtholi" ehunyushwa njengomqalisi wesiko lamaqoqo ezinkanyezi asendulo, khona-ke uPtolemy uvame ukusetshenziswa njengereferensi eyinhloko ngoba imibhalo yakhe inethonya elikhulu.
Umehluko phakathi kwe-Constellation ne-Asterism
Ezingxoxweni ngamaqoqo ezinkanyezi, igama elithi asterism liyavela futhi. I-asterism iyiphethini yezinkanyezi ethandwayo neyaziwa kabanzi, kodwa akuyona iqoqo lezinkanyezi elisemthethweni. Isibonelo esaziwayo yi-Big Dipper, i-asterism eqoqweni lezinkanyezi i-Ursa Major. Ngakho-ke, akuwona wonke amaphethini ezinkanyezi ajwayelekile ayiqoqo lezinkanyezi elisemthethweni ngokuzenzakalelayo.
Isiphetho
I-constellation yiqembu lezinkanyezi ezibonakala zakha iphethini futhi, ku-astronomy yanamuhla, iyisifunda esisemthethweni endaweni yasezulwini. Ama-constellations awazange atholwe ngumuntu oyedwa, kodwa kunalokho angumphumela wokubuka namasiko avela emiphakathini eyahlukahlukene eminyakeni eyizinkulungwane edlule. Ngokwesiko laseNtshonalanga, uPtolemy ungumuntu obalulekile ekubhaleni ama-constellations angu-48 akudala e-Almagest. Phakathi naleso sikhathi, ukumiswa kwezinkanyezi kwanamuhla njengezifunda ezingu-88 ezisemthethweni kwenziwa yi-IAU ngekhulu lama-20, ngeminikelo evela kososayensi abanjengo-Eugène Delporte. Ngokuqonda ama-constellations, asigcini nje ngokufunda izinkanyezi kodwa futhi silandelela umlando wesintu ekufundeni nasekunikezeni incazelo esibhakabhakeni sasebusuku.
