I-Messier 39

isiqephu 39

Itholakala kumlaza i-Cygnus, phakathi kwe-Deneb ne-Cocoon Nebula (IC 5146), ilele iqoqo lenkanyezi evulekile elithakazelisayo. Ngokubuka kwethu Emhlabeni, le nto yasezulwini yaziwa ngokuthi i-Messier 39. Nokho, iphinde ibalwe kukhathalogi ye-NGC njenge-NGC 7092, ehlelwe njenge-Mel 236 kukhathalogi yakwa-De Melotte futhi ikhonjwe njenge-Cr 438 kukhathalogi Collinder.

Kulesi sihloko sizokutshela zonke izici nokubaluleka mayelana uMesiya 39 kanye nekhathalogi yonke.

I-Messier 39

izinkanyezi esibhakabhakeni

Leli qoqo lezinkanyezi, elitholakala cishe eminyakeni engu-800 yokukhanya, ligqama njengelinye lamaqoqo aseduze avulekile esingakwazi ukuwafinyelela. Ihlanganiswe cishe izinkanyezi ezingu-30, kukhona ezimbalwa, cishe ezingu-10, ezikhanya ngokugqamile ngama-magnitude aphakathi kuka-6 no-9. Ukwengeza, leli qoqo lihlanganisa indawo enkulu esibhakabhakeni, uma kuqhathaniswa nobukhulu beNyanga egcwele. Ngobukhulu obubonakalayo obungu-4,6 nokukhanya kwendawo okungu-11,8 mag/min arc2, ikhipha ukukhanya okubalulekile.

Leli qoqo elivuliwe lathwetshulwa esithombeni ngo-December 8, 2018, kusetshenziswa i-Skywatcher 200/1000 ebonisa isibonakude kanye nekhamera yeCanon EOS 550D, njengoba kubonakala ku-Querol. Ngobukhulu obungatholakali kalula ngeso lenyama, le nto yasezulwini isemngceleni wokubona komuntu. Nokho, lapho ibhekwa ngezibonakude, ubukhona bayo buba sobala. Ngenxa yokwandiswa kwayo okukhulu, kuyatuswa ukuyibuka ngezibonakude noma isibonakude sokukhulisa esiphansi. Abanye bathi bayibonile ngaphandle kosizo, kodwa ngaphansi kwesimo sesibhakabhaka esimnyama bhuqe futhi ngaphandle kokukhanyisa okwenziwayo, futhi nalapho kubonakala njengokufiphala.

Ubani owayithola?

isiqephu 39

Umzingeli wenkanyezi enomsila uCharles Messier kuthiwa wathola ngokusemthethweni le nto yasemkhathini ngo-1764. Nokho, abanye bathi isazi sezinkanyezi saseFrance uGuillaume Le Gentil wasithola ngempela ngo-1750 , okubonakala kunengqondo uma kucatshangelwa ukungabikho kokungcola kokukhanya ngesikhathi sakhe. Ngaphansi kwezimo ezifanele, kungenzeka ukubona lesi simo ngeso lenyama.

Njengamaqoqo amaningi avulekile, I-M39 iqukethe iqoqo lezinkanyezi ezincane ezavela ku-nebula eyodwa futhi zavela kanyekanye. Ngokunembayo, izinkanyezi eziku-M39 zineminyaka engaba yizigidi ezingu-300 ubudala, okubonisa ubusha bazo obuhlobene (uma siqhathanisa, iLanga lethu liphila iminyaka engaba yizigidi eziyizinkulungwane ezingu-5).

Ithini ikhathalogi ye-Messier?

iqoqo lezinkanyezi

I-Messier Catalogue iyinhlanganisela yezinto zezinkanyezi ezibhalwe ngokucophelela. Ngo-1774, isazi sezinkanyezi esingumFulentshi uCharles Messier sahlanganisa uhlu oluphelele lwezinto ezingu-110 zezinkanyezi ezaziwa ngokuthi i-Messier Catalogue.

UMessier ayegxile kakhulu kukho kwakuwukuthola izinkanyezi ezinomsila, kodwa wabhekana nenselele yokuzama ukuhlukanisa phakathi kwezinto ezisatshalaliswa esibhakabhakeni kanye nezinkanyezi ezinomsila zangempela esebenzisa izibonakude ezazitholakala ngesikhathi sakhe. Ukuze aphendule lo mbuzo, uMessier wazibophezela ekuhlanganiseni uhlu olungeke lusize yena kuphela kodwa nabanye abazingeli benkanyezi enomsila ukuhlukanisa kalula izinto ezaziwa kuma-comet angaba khona. Ngale ndlela, Babengeke baphazame lezi zakhiwo ezilufifi esibhakabhakeni njengezinkanyezi ezinomsila ezintsha.

Ikhathalogi kaMessier iyinhlanganisela yezinto ezihlukahlukene zasemkhathini, okuhlanganisa ama-nebulae, amaqoqo ezinkanyezi ezivulekile neziyimbulunga yonke, nemithala, ebonisa imvelo yazo ehlukahlukene. UMessier wahlola ngokucophelela lokho okuphawulwe izazi zezinkanyezi zangaphambili, eqinisekisa ukunemba kwako. Ngaphezu kwalokho, wahlanganisa okutholwe yisazi sezinkanyezi uPierre Meschen, ababe nesandla ekuhlonzweni cishe kwesigamu sezinto ezisohlwini lwekhathalogi kaMesiya. Ukwengezwa kokuqala kwaleli qoqo kwakuwumthala ovunguzayo owaziwa ngokuthi i-M63. UMessier wakuqinisekisa ngenkuthalo ukwaziswa okunikezwe uMeschen futhi wakufaka ohlwini lwakhe olubanzi.

Ukuvela kwekhathalogi ye-Messier

Ngo-1774, ukushicilelwa kokuqala kohlu lukaMesiya kwakuhlanganisa ingqikithi yezinto ezingu-45. Ngokushesha phambili ku-1781, lapho kushicilelwa uhlelo lokugcina, ukwandisa ikhathalogi ukuze ihlanganise ingqikithi yezinto eziyi-103.

Ekuqaleni uMessi wayehlose ukuphetha ikhathalogu yakhe ngezinto ezingu-100 zasezulwini ezihlaba umxhwele. Nokho, ngaphambi nje kokuba umbhalo wesandla wokugcina ulungele ukushicilelwa, uMeshen wembula ukuthi kukhona ezinye izinhlangano ezintathu ezengeziwe. Ngeshwa, umsebenzi kaMessier kukhathalogi wamiswa kungazelelwe ngenxa yokulimala kanzima. Ngaphezu kwalokho, isazi sezinkanyezi esiyiNgisi uWilliam Herschel, esasihlome ngamathuluzi athuthuke kakhulu, sadlula lokho okwafezwa uMesiya ngokuhlanganisa ikhathalogu eyayihlanganisa izinto ezimangalisayo ezingu-2.500 XNUMX.

Ngemva kokushona kukaMesiya, ikhathalogi yayo yanwetshwa ukuze ifake i-M110, ngoba wayebone izinto ezithile kodwa engaziqambi ngezinombolo ngazinye. I-Meshen yathatha i-M104 - M107. Ngaphezu kwalokho, kwase kubhekiselwe ku-M108 naku-M109 encazelweni ye-M97.

U-Messier, nakuba abona i-M110, isiphuphutheki se-Andromeda Nebula, akakubonanga njengokubalulekile ukuyichaza ngegama elithile lezinombolo.

Iqoqo elaziwa ngokuthi i-Messier's Catalogue lihlaba umxhwele kakhulu labo abenza isayensi yezinkanyezi njengento yokuzilibazisa. Okwenza ithakazelise nakakhulu ukuthi yahlanganiswa ngasekupheleni kwekhulu le-18, isikhathi lapho izibonakude zazingenawo amakhono amangalisayo ezinawo namuhla. Yingakho ke, Izinto zasezulwini ezikhanya kakhulu kuphela ezivela kukhathalogi kaMessier, okuyizona futhi okulula ukuzibona ngesibonakude sezinganekwane. Kodwa-ke, kunezinkampani eziphawulekayo ezingazange zisike kukhathalogi kaMessier. Isibonelo, amaqoqo enkanyezi e-Chi ne-Ash Perseus (NGC 884 ne-NGC 869) noma umthala we-Leo NGC 3628, ophawuleka njengozakwabo abangomakhelwane i-M65 ne-M66.

Kosonkanyezi abayizimfundamakhwela, i-NGC inikeza ikhathalogi ebanzi kakhulu yemithala nama-nebula, nakuba ukubheka okuningi kwakho kudinga ukusetshenziswa kwezinto ezithuthuke kakhulu kunetheleskopu evamile. Njengoba izinto zitholwa futhi zirekhodwa kukhathalogi, zinikezwa izinombolo ezilandelanayo futhi zikhonjwe ngohlamvu 'M' owandulela inombolo.

Ngithemba ukuthi ngalolu lwazi ungafunda okwengeziwe ngoMesiya 39 nezici zakhe.
