Nhema yezuva nezuva uye magetsi ekushaikwa
Chii ichi? Zvimwe zviratidzo zvezuva zvinoratidzwa nechiedza chemativi eguta, uye izvi zvinoita kuti mhepo yezuva iite mavara. Mavara aya anoonekwa sezviratidzo zvechokwadi kubva kustar catalog uyewo kuti ndezvipi zvakanga zvavharwa kana kuti zvaive zviri nani, kubva panzvimbo dzakaomarara kusvika kumaruwa.
Maitiro ekuishandisa: Dzvanya pane iyo bhokisi rezvinyorwa kuti uwane ruzivo rwekuonekwa kwezuva.
Ndeipi mvura yacho?
Dzvanya pane imwe yezviratidzo zvinoratidzwa. Choona kuti ndeipi inooneka panzvimbo yauri kugara. Kana uchida, sarudza imwe chete inoratidza zviratidzo zveOrion zvaunogona kuona panzvimbo iyi.
Zvita zvinzvimbo uye kutonhora kubva kuYale Bright Star Catalogue. Location yako haisi kuzochengetwa.
Tarisa izvi
- Kutanga pachikamu 1 (a chaizvo dark site) uye slowly kudhonza kuti 9.Nharaunda: From about 9,000 stars across the whole sky, only about 400 are left in a city centre, and only half of the sky is above you at any time.
- Choose Orion uye uenzanise mativi 4 ne8.Nharaunda: Chimiro chinozivikanwa chinogara, asi zvitanhatu zvinotyisa izvo zvinozadza, uye nzira yeMweya Mutsvene yakati, inodzokera.
- Pazuva rinotevera rakajeka, pasina mwedzi, enda kunze uchibva kumamwe mapoka ezuva uye mirira 20 maminitsi kuti amehlo ako agadzikane.Nharaunda: Tarisa ipapo kuti ndeipi mifananidzo inoenderana nezvauri kuona: izvi zvinoreva kuti ndeipi Bortle yako. Mifananidzo inoratidzwa iri muOrion area; chero imwe yaunoziva yezviratidzo inogona kushandiswa.
Maitiro ari kutevera
Chii chinogona kuita munhu wese?
Kukuvadza mhepo kunogadziriswa nyore: tinya bhatiri uye hapana chacho. Tinya mabhatiri ekunze, uwane chiedza chekuzvidzivirira, shandisa mabhatiri ane ruvara rwakanaka uye tinya mabhatiri asina munhu anoshandisa.
Zvinyorwa: zviratidzo zvenzvimbo uye kuratidzwa kubva ku Yale Bright Star Catalogue (5th revised edition). Mativi enyika neakanyanya kuonekwa zviratidzo kubva ku J. E. Bortle, "Introducing the Bortle Dark-Sky Scale", Sky & Telescope, February 2001. Kuratidzwa kwemashoko: DarkSky International. Location yako haizobvunzwa kana kuchengetwa.
Chiedza chinogadzirwa nevanhu chinoonekwa panzvimbo dzisina kufanira, kunyanya pasi. Icho chinoita kuti nyika yose iite seyakajeka uye ichibvisa zvitanhatu.
More in the glossary →A 1 kusvika 9 scale yekuti sei yakadzikama usiku chiedza, akaburitswa neamateur astronomer John E. Bortle mu 2001. Level 1 ndiro chakadzikama chiedza panyika; level 9 inzvimbo yeguta.
More in the glossary →The scale astronomers use for brightness. Bigger numbers mean fainter: the brightest stars are around magnitude 0 or 1, and the faintest you can see from a truly dark site are about magnitude 7 to 8.
More in the glossary →Akadzingwa nezuva, anenge 20 kusvika 30 maminitsi, uye kana uchitarisa pascreen kana mubhatiri rakanaka, zvinongoita kuti uone zvakanaka.
