Yadda Ake Gano Taurari a Sama Mai Dare
Lura da sararin samaniya na dare koyaushe yana da nasa kyan gani. Bayan walƙiyar taurari da ke kama da bazuwar, akwai wasu alamu da mutane suka gane tsawon dubban shekaru a matsayin taurari. Taurari suna taimaka wa matuƙan jirgin ruwa su yi tafiya, manoma suna tantance yanayi, kuma masana kimiyya suna tsara sararin samaniya. Duk da haka, ga masu farawa, samun "hoton" tauraro a cikin dubban wuraren haske na iya zama da rikitarwa. Wannan labarin zai tattauna yadda ake gano taurari kusan, daga shiri zuwa matakai masu amfani a fagen.
1. Fahimci farko: Taurari vs taurari
Kafin mu fara, yana da muhimmanci mu bambance tsakanin kalmomi guda biyu:
– Tauraron taurari (na hukuma) yanki ne da ke kan sararin samaniya wanda Ƙungiyar Tauraron Falaki ta Duniya (IAU) ta ayyana. A halin yanzu akwai tauraro 88 na hukuma.
– Taurari wani sanannen tsari ne na tauraro wanda galibi yake aiki a matsayin "alamar jagora" amma ba tambarin hukuma ba ne, misali Big Dipper wanda yake ɓangare na Ursa Major.
Sanin waɗannan bambance-bambancen yana taimaka maka ka guji rikicewa lokacin da app ko sky map suka nuna suna wanda ya bambanta da wanda ka saba da shi.
2. Kayyade lokaci mafi kyau don lura
Taurarin taurari da ake gani suna canzawa dangane da lokacin rana da yanayi. Sama da karfe 7:00 na yamma za ta bambanta da sama da karfe 2:00 na safe, kuma sama da za ta yi a watan Yuni za ta bambanta da sama da za ta yi a watan Disamba.
Wasu shawarwari don zaɓar lokaci:
– Zaɓi dare mai haske ba tare da gajimare masu kauri ba.
– A guji ganin taurari masu yawa idan ana son ganin taurari da yawa, domin hasken wata yana rage bambanci.
– Mafi kyawun lokaci yawanci shine bayan sararin sama ya yi duhu gaba ɗaya (kimanin sa'o'i 1-2 bayan faɗuwar rana) har zuwa wayewar gari.
Idan kana zaune a yankin da ke da wurare masu zafi kamar Indonesia, ana iya ganin taurari da yawa a duk shekara, amma matsayinsu da tsayinsu har yanzu za su canza dangane da yanayi.
3. Nemi wurin da babu gurɓataccen haske.
Babban abokin gaba na kallon taurari shine gurɓataccen haske daga hasken birni. Da zarar sararin samaniya ya yi duhu, to da sauƙin ganin taurari marasa ƙarfi da ke samar da taurari.
Domin samun sakamako mafi kyau:
– Je zuwa wani wuri mai faɗi kamar duwatsu, bakin teku, ko kuma wani yanki na karkara.
– Kashe fitilun da ba dole ba kuma a guji kallon allo masu haske.
– Ka ba idanunka lokaci don su saba da duhu na tsawon mintuna 15-30.
Daidaita ido yana da matuƙar muhimmanci; bayan ƴan mintuna, za ku fara ganin taurarin da ba a iya gani a da.
4. San manyan alkibla da wuraren nuni na sama
Don gano taurari, kuna buƙatar sanin kwatancen: arewa, kudu, gabas, da yamma. Kuna iya amfani da:
- Kamfas (ta jiki ko ta hannu)
– Alamomin ƙasa na halitta (misali faɗuwar rana a yamma)
- Aikace-aikacen ilmin taurari wanda ke nuna yanayin sararin samaniya a ainihin lokaci
Baya ga alkibla, kuma ku san tsayin taurari daga sararin sama. Wasu taurari suna bayyana ne kawai a ƙasa a sararin sama, yayin da wasu kuma za su iya kasancewa kai tsaye a sama (zuwa saman).
5. Yi amfani da "tauraro mai tsalle"
Hanya mafi inganci ga masu farawa ita ce tsalle-tsalle daga taurari masu haske, waɗanda ke ɗauke da tsalle daga tauraro mai haske, mai sauƙin ganewa zuwa tsarin da ake so. Fara da tauraro mafi shahara.
Wasu taurari masu haske waɗanda galibi ana amfani da su azaman nassoshi:
– Sirius (mafi haske a sararin sama na dare) – yana cikin ƙungiyar taurarin Canis Major
– Canopus – mai haske sosai, ana iya gani a sarari daga yankin kudu
– Arcturus, Vega, Capella, Altair, Antares (ya danganta da yanayi da wurin da ake ciki)
Ta hanyar gano tauraro ɗaya mai haske, za ka iya gano wata alama ta tunani zuwa ga taurarin da ke kewaye.
6. Fara da taurarin da aka fi sani da su cikin sauƙi.
Ga wasu taurari/taurari waɗanda galibi sune mafi sauƙi ga masu farawa:
a) Orion (Mafarauci)
Orion "wanda aka fi so" ne saboda siffarsa mai haske.
Babban fasali:
– Taurari uku sun daidaita don samar da Bel ɗin Orion.
– A ƙarƙashin bel ɗin akwai “takobi” wanda zai iya nuna zuwa ga Orion Nebula idan sararin samaniya ya yi duhu sosai.
– Taurari biyu masu haske: Betelgeuse (ja) da Rigel (shuɗi).
Shawara: Da zarar ka sami bel ɗin Orion, za ka iya amfani da layukansa don nemo wasu taurari kamar Sirius.
b) Crux (Kudancin Cross)
A yankin kudu, Crux ya shahara sosai.
Babban fasali:
– Manyan taurari guda huɗu suna samar da siffar giciye.
– Sau da yawa ana amfani da shi don taimakawa wajen tantance alkiblar kudu.
Lura: A wasu wurare, Crux na iya bayyana a ƙasa a sararin sama, don haka zaɓi wuri mai faɗi da ke kallon kudu.
c) Scorpius (Kura)
Ana iya gane Scorpius cikin sauƙi ta hanyar tauraruwarsa.
Babban fasali:
– Tauraron mai haske ja Antares shine "zuciyar" kunama.
– Siffa kamar harafin "S" ko dogon ƙugiya.
Wannan yawanci yakan bayyana ne a wasu watanni lokacin da dare ya fi haske.
7. Yi amfani da taswirar sararin samaniya ko manhajoji cikin hikima
Akwai manyan kayan aiki guda biyu:
1) Taswirar sararin samaniya da aka buga (planisphere)
Amfani: babu walƙiya, babu buƙatar batura, yana da kyau don fahimtar koyo.
Yadda ake amfani da shi: juya bisa ga kwanan wata da lokaci, sannan daidaita alkiblar taswirar da alkiblar da kake fuskanta.
2) Manhajojin ilmin taurari (misali Stellarium, SkySafari, Star Walk, da sauransu)
Amfani: yana da matuƙar amfani, yana iya nuna sunayen taurari da taurari kai tsaye ta kyamarar.
Domin kada ya lalata daidaitawar ido:
– Kunna yanayin dare (yanayin ja) idan akwai.
– Rage hasken allon.
Amma kada ka dogara da manhajoji da yawa. Ka yi ƙoƙarin haddace muhimman tsare-tsare domin ka iya gane taurari ba tare da taimako ba.
8. Kula da tsarin, ba yawan taurari ba.
Masu farawa galibi suna ɓacewa suna ƙoƙarin haɗa dukkan taurari. Mabuɗin gane taurari shine a mai da hankali kan:
- tsarin zane
- nisan da ke tsakanin taurari
- tauraro mafi haske a matsayin anga
Misali, Orion ba wai game da dukkan taurarin da ke kewaye da shi ba ne, a'a, bel ce mai matuƙar bambanta. Da zarar an kafa babban tsari a cikin kanka, ƙarin taurari za su yi ma'ana cikin sauƙi.
9. Yi hankali da "taurari na ƙarya": duniyoyi da tauraron dan adam
Wani lokaci abin da kake tunanin tauraro ne mai haske a zahiri duniya ce, musamman:
- Venus (mai haske sosai, yawanci kusa da sararin sama a lokacin faɗuwar rana ko fitowar rana)
– Jupiter (mai haske da kwanciyar hankali)
- Mars (yana da launin ja)
– Saturn (ya fi Jupiter rauni amma har yanzu yana da ban mamaki)
Siffa mai bambantawa: taurari yawanci suna kama da suna "ƙara haske" sosai, yayin da taurari ke samun haske mai ƙarfi (kodayake wannan ya dogara da yanayin yanayi).
Ana iya ganin tauraron dan adam na wucin gadi a matsayin ɗigo masu haske suna tafiya a hankali a sararin samaniya. Wannan abu ne na al'ada kuma ba ya tsoma baki ga gano taurari matuƙar kun mai da hankali kan tsarin taurari mai tsayayye.
10. Yi aikin lura da kuma rubuta bayanai.
Ikon gane taurari yana inganta da aiki. Gwada waɗannan:
– A riƙa yin minti 15-30 a kowane lokaci sau ɗaya a mako.
– Zaɓi taurari 1-2 don yin nazarin kowane zaman.
– Yi bayanin kula: kwanan wata, lokaci, wuri, yanayin sararin sama, da kuma taurarin da ake iya gani.
– Gwada zana tsarin tauraro mai sauƙi. Ba lallai ne ya zama mai kyau ba; manufar ita ce horar da ƙwaƙwalwar gani.
Cikin 'yan makonni kaɗan, za ku fara fahimtar "taswirar" sararin samaniya ta halitta.
Penutup
Gano taurari a sararin samaniya na dare ƙwarewa ce mai daɗi da annashuwa. Mabuɗin shine zaɓar lokaci da wuri da ya dace, fahimtar yanayin tafiyarku, amfani da taurari masu haske a matsayin jagora, da kuma yin aiki don gane muhimman alamu. Da taimakon taswirar sararin samaniya ko manhaja—ba tare da dogaro da su sosai ba—nan ba da daɗewa ba za ku iya "karanta" sararin samaniya kamar babban taswira, yana canzawa daga lokaci zuwa lokaci. Da zarar kun duba sama kuma kuka lura, haka taurarin za su ji, kamar kuna da kamfas na halitta da aka ba ku daga masu kallon sararin samaniya a tsawon tarihi.
Idan kana so, zan iya yin jerin taurarin da suka fi sauƙin gani musamman ga Indonesia bisa ga watan (Janairu-Disamba) tare da alkiblar da suke bayyana.
