Mphatso ya mwanga

Kwa zaka mamiliyoni ambiri, aliyense amene anayang’ana pamwamba pa usiku woyera anaona chinthu chimodzi: ziwanda za nyenyezi ndi mtsinje wa Milky Way. Anapanga kalendala, maulendo, miyambo ndi sayansi. M’moyo umodzi taziyika pansi pa khoma lowala la dzuwa lomwe lidawonongedwa. The Light Initiative ilipo kuti ibweretsenso, ndipo iyi ndi vuto limodzi lachilengedwe lomwe lingasinthidwe usiku womwe musankha kukhazikitsa.

Mdima wa usiku m’mawerengedwe

According to the world atlas of artificial sky brightness, 80 percent of the world’s people, and 99 percent of people in the United States and Europe, live under light-polluted skies. One in three people on Earth can no longer see the Milky Way from where they live. Ndipo izi zikuchepa: mamiliyoni ambiri a anthu odziwa zasayansi akuwerengera ziwanda zinapeza kuti nyanja ya usiku idawala ndi pafupifupi 9.6 peresenti chaka chilichonse pakati pa 2011 ndi 2022, yomwe imadutsa kuwala m’maola asanu ndi awiri.

Nkhani yabwino

Kusiyana ndi magazi a greenhouse, kusefukira kwa dzuwa sikuwonjezeka. Kutseka, kuteteza kapena kuwala kwa lampu ndi nyengo yozizira imabwerera nthawi yomweyo. Zosinthazi ndi zotsika mtengo, zomwe zimapezeka m’masitolo onse a zida, ndipo nthawi zambiri zimapulumutsa ndalama pamagetsi. Mizinda yonse, zilumba ndi mapaki padziko lonse lapansi anakhala malo ovomerezeka a dark-sky posintha magetsi awo.

Kuwononga mpweya ndi kokha komwe kumatha kuwonongeka nthawi yomweyo pamene mumawachotsa.

Zimene Light Initiative imachita

• Imafotokoza za kusefukira kwa dzuwa ndi zotsatira zake m’njira yosadziwika bwino: onani chiyani chikusefukira cha dzuwa.
• Ikusonyeza momwe mungachitire, ndi malangizo othandiza kwa maofesi, bizinesi ndi mizinda: onani kuwala kunja mosamala.
• Kugwirizana kwa nyanja ndi kuphunzira. Tikugwiritsa ntchito space learning platform yathu yaulere yomwe imayamba ndi nyanja pamwamba pa inu.
• Kuthandiza ntchito za m’deralo, monga usiku wa chiwanda, kuwerengetsa magalasi ndi kukambirana ndi zipani, zomwe zimachitikira ndi ogwira ntchito mwakhama pogwiritsa ntchito boma la malipiro.

Kodi nyanja yanu ndi yofiira bwanji?

The Mapa a Kuwononga Kwamawala Kuwala kwa dzuwa ndi Yurij Stare kusonyeza kukoma kwa dzuwa kopangidwa ndi munthu kulikonse padziko lapansi, mogwirizana ndi deta ya satellite. Projekiti ya sayansi ya anthu Globe at Night imalola aliyense kuyesa dziko lapansili ndi chilichonse koma maso awo, ndipo amawonjezera kuchuluka kwanu ku rekodi yapadziko lonse.

Momwe mungathandize

• Kuwerengera ziwanda zanu. Kutenga nawo mbali pa Globe at Night nthawi zina m’chaka; kuganizira kwanu kumasintha kukhala deta.
• Fixed wanu owala okha kawiri: kuteteza iwo, kuwaika pansi, kutentha iwo, kuwadula ndi kuwaika pa ma timers kapena ma sensors a m’manja.
• Kuyankhula ndi anzanu. Ambiri owala magetsi amatengedwa pa chizolowezi, si zofunika. Kulankhulana kwachikondi ndi buku la nkhani limeneli nthawi zambiri kumathandiza.
• Ikani lamuloli pa msonkhano wanu. Funsani za malamulo a zowunikira ndi kuteteza kwabwino, kutentha kwa mtundu wotentha wa 3000 K kapena pansipa, kuwala kotsika pambuyo pamdima, komanso kuteteza mapiri ku dzuwa lofiira.
• Funsani makampani kuchotsa zilembo ndi magalimoto oyendetsa galimoto pambuyo potseka.
• Kuchita mwambo wa nyenyezi. Teleskopu pa usiku woyera imasintha maganizo mofulumira kuposa chilichonse cha statistics. Kuyamba imodzi mwa contribution board.
