Caption: Second place in the 2021 IAU OAE Astrophotography Contest, category Light pollution.

This composite image taken in Slovakia in 2020 illustrates the effect due to artificial illumination of light polluted areas. The higher the level of light pollution, the less we can observe in the sky, notice how the number of stars visible even to a sensitive digital camera decreases from right to left. Light pollution not only affects the visibility of objects in the night sky, but also significantly impacts ecosystems, negatively affecting many animals, such as migratory night birds, which may encounter difficulties to find the direction to where they should migrate to, or the sea turtles, which may be confused by the lights from coastal cities located near the beaches where they are supposed to spawn. Light pollution can also negatively impact some human health. Therefore, it is important to preserve the dark and quiet night sky for the benefit of the entire planet and all the diverse life it supports.

Caption: الصورة الفائئزة بالمركز الثاني في مسابقة التصوير الفلكي لمكتب تعليم الفلك لعام 2021 فئة التلوث الضوئي.

توضح هذه الصورة المركبة التي التقطت في سلوفاكيا عام 2020 تأثير التلوث الضوئى الناتج عن الإضاءة الإصطناعية لبعض المناطق. وتوضح الصورة انه كلما ارتفع مستوى التلوث الضوئي ، قل ما نلاحظه في السماء ويمكن ملاحظة كيف أن عدد النجوم المرئية يتناقص من اليمين الى اليسار حتى للكاميرا الرقمية الحساسة. كما ان التلوث الضوئي لايؤثر فقط على رؤية الأجسام في سماء الليل بل يؤثر أيضًا بشكل كبير على النظم البيئية، مما يؤثر سلبًا على العديد من الحيوانات ، مثل الطيور الليلية المهاجرة ، والتي قد تواجه صعوبات في العثور على الاتجاه الصحيح إلى المكان الذي يجب أن تهاجر إليه ، أو السلاحف البحرية ، والتي قد تختلط عليها الأضواء من المدن الساحلية الواقعة بالقرب من الشواطئ حيث من المفترض أن تفرخ.. كما أن التلوث الضوئي يؤثر أيضًا بشك سلبى على صحة الإنسان. لذلك ، من المهم الحفاظ على هدوء الليل وظلمة السماء وهذا لصالح الكوكب بأسره ولدعم كل اشكال الحياة المتنوعة عليه.

Caption: Secondo posto al concorso di astrofotografia IAU OAE 2021, categoria Inquinamento luminoso.

Questa immagine composita, scattata in Slovacchia nel 2020, illustra l'effetto dovuto all'illuminazione artificiale delle aree inquinate dalla luce. Maggiore è il livello di inquinamento luminoso, minore è la quantità di stelle che possiamo osservare nel cielo; si noti come il numero di stelle visibili anche a una sensibile fotocamera digitale diminuisca da destra a sinistra. L'inquinamento luminoso non solo influisce sulla visibilità degli oggetti nel cielo notturno, ma ha anche un impatto significativo sugli ecosistemi, influenzando negativamente molti animali, come gli uccelli notturni migratori, che possono incontrare difficoltà nel trovare la direzione verso cui migrare, o le tartarughe marine, che possono essere confuse dalle luci delle città costiere situate vicino alle spiagge dove dovrebbero deporre le uova. L'inquinamento luminoso può anche avere un impatto negativo sulla salute umana. È quindi importante preservare un cielo notturno buio e silenzioso per il bene dell'intero pianeta e di tutte le diverse forme di vita che sostiene.
