This page describes an image Northern Lights Color
Image caption:
This photograph taken with a smartphone captures the ethereal beauty of the Northern Lights at Cassidy Point, Yellowknife, NT, Canada on 24 March 2023, at temperatures well below freezing (–29°C). The mesmerising dance of the Aurora Borealis (Australis), commonly known as the Northern (Southern) Lights, paints the night sky in striking hues. The aurora is a natural phenomenon caused by charged particles from the Sun interacting with Earth’s atmosphere, and being redirected by Earth’s magnetic field towards the north and south polar regions. The charged particles excite atoms and molecules in the atmosphere, resulting in a light display that varies in colour and form. The different colours of an aurora are determined by the gases (atoms and molecules) in Earth's atmosphere, the altitude of the aurora, the density of the atmosphere, and the energy of the charged particles. In general, green is attributed to oxygen molecules, red is associated with high-altitude oxygen molecules, purple and blue are associated with hydrogen and helium, and pink auroras are typically associated with nitrogen. On this particular night, the serene environment of Cassidy Point provided an unobstructed view of the lights. In the foreground, Aurora Village can be seen, a site renowned for organised tours to witness this spectacle.

Image caption: Vincitore del concorso di astrofotografia IAU OAE 2023, categoria Immagini fisse con smartphone-dispositivi mobili: Colori dell'Aurora Boreale, di Jason Johnson
Questa fotografia è una delle sei vincitrici della categoria Immagini fisse scattate esclusivamente con smartphone/dispositivi mobili. Cattura la bellezza eterea dell'aurora boreale a Cassidy Point, Yellowknife, NT, Canada, il 24 marzo 2023, a temperature ben al di sotto dello zero (-29°C). L'ipnotica danza dell'Aurora Boreale (Australis) dipinge il cielo notturno con sfumature suggestive. L'aurora è un fenomeno naturale causato da particelle cariche provenienti dal Sole che interagiscono con l'atmosfera terrestre e vengono reindirizzate dal campo magnetico terrestre verso le regioni polari nord e sud. Le particelle cariche eccitano gli atomi e le molecole dell'atmosfera, dando vita a uno spettacolo luminoso che varia nei colori e nella forma. I diversi colori di un'aurora sono determinati dai gas (atomi e molecole) presenti nell'atmosfera terrestre, dall'altitudine dell'aurora, dalla densità dell'atmosfera e dall'energia delle particelle cariche. In generale, il verde è attribuito alle molecole di ossigeno, il rosso è associato alle molecole di ossigeno ad alta quota, il viola e il blu sono associati all'idrogeno e all'elio, mentre le aurore rosa sono tipicamente associate all'azoto. In questa notte particolare, l'ambiente sereno di Cassidy Point ha permesso di vedere le luci senza ostacoli. In primo piano si vede l'Aurora Village, un sito rinomato per i tour organizzati per assistere a questo spettacolo.

Image caption: 这张使用智能手机拍摄的照片捕捉到了加拿大西北地区黄刀镇卡西迪角于2023年3月24日的北极光瑰丽景色，当时的气温远低于冰点（-29°C）。极光的迷人舞动，为夜空描绘出引人注目的色彩。极光（英文也可以写为“Northern (Southern) Light”）是一种自然现象，由太阳带电粒子与地球大气层相互作用，并被地球磁场引至南北极地区而产生。这些带电粒子激发了大气中的原子和分子，产生了形态和颜色各异的光显示。极光的不同颜色取决于地球大气中的气体（原子和分子）、极光的高度、大气的密度以及带电粒子的能量。一般来说，绿色归因于氧分子，红色与高空氧分子有关，紫色和蓝色与氢和氦有关，而粉色极光通常与氮有关。在这个特定的夜晚，卡西迪角宁静的环境提供了一个无遮拦的视野来欣赏这奇观。在前景中，可以看到极光村，这是一个以组织观赏极光而闻名的地点。
