Aurorae are the result of ionisation and excitation processes in Earth's upper atmosphere, caused by charged particles from the solar wind or from coronal mass ejections. The different colours in an aurora display indicate the species of atmospheric atoms and molecules involved. The most common colour is a bright green, which, together with deep red, originates from atomic oxygen. Blue, purple and pink hues are much rarer and originate from molecular nitrogen. The reflection of the aurora in the water indicates the brightness of intense aurorae at higher latitudes.

Image caption: ২০২১ এইএইউ ওএই অ্যাস্ট্রোফটোগ্রাফি প্রতিযোগিতায় প্রথম স্থান, বিভাগ অরোরা (এখনও ছবি)
অরোরা হল পৃথিবীর উপরের বায়ুমণ্ডলে আয়নিকরণ এবং উত্তেজনা প্রক্রিয়ার ফলাফল, যা সৌর বায়ু থেকে আধানযুক্ত কণা বা করোনাল ভর নির্গমন থেকে সৃষ্ট। একটি অরোরা ডিসপ্লেতে বিভিন্ন রং বায়ুমণ্ডলীয় পরমাণু এবং জড়িত অণুগুলির প্রজাতি নির্দেশ করে। সবচেয়ে সাধারণ রঙ একটি উজ্জ্বল সবুজ, যা গভীর লালের সাথে একত্রে পারমাণবিক অক্সিজেন থেকে উদ্ভূত হয়। নীল, বেগুনি এবং গোলাপী রঙগুলি অনেক বিরল এবং আণবিক নাইট্রোজেন থেকে উদ্ভূত। জলে অরোরার প্রতিফলন উচ্চ অক্ষাংশে তীব্র অরোরার উজ্জ্বলতা নির্দেশ করে।

Image caption: Première place au concours d'astrophotographie 2021 de l'IAU OAE, catégorie Aurores (images fixes)
Les aurores sont le résultat de processus d'ionisation et d'excitation dans la haute atmosphère terrestre, causés par des particules chargées provenant du vent solaire ou d'éjections de masse coronale. Les différentes couleurs d'une aurore indiquent les espèces d'atomes et de molécules atmosphériques impliquées. La couleur la plus courante est le vert vif, qui, avec le rouge profond, provient de l'oxygène atomique. Les teintes bleues, violettes et roses sont beaucoup plus rares et proviennent de l'azote moléculaire. La réflexion de l'aurore dans l'eau indique la luminosité des aurores intenses à des latitudes plus élevées.

Image caption: Primo posto al concorso di astrofotografia IAU OAE 2021, categoria Aurorae (immagini fisse)
Le aurore sono il risultato di processi di ionizzazione ed eccitazione nell'alta atmosfera terrestre, causati da particelle cariche provenienti dal vento solare o da espulsioni di massa coronale. I diversi colori di un'aurora indicano le specie di atomi e molecole atmosferiche coinvolte. Il colore più comune è il verde brillante che, insieme al rosso intenso, deriva dall'ossigeno atomico. Le tonalità blu, viola e rosa sono molto più rare e provengono dall'azoto molecolare. Il riflesso dell'aurora nell'acqua indica la luminosità delle aurore intense alle latitudini più elevate.

极光是地球高层大气电离和激发过程的结果，由太阳风或日冕物质抛射产生的带电粒子引起。极光中不同的颜色显示了参与反应的大气原子和分子的种类。最常见的颜色是明亮的绿色，它与深红色一起源自原子氧。蓝色、紫色和粉色的色调则较为罕见，来源于分子氮。极光在水中的倒影显示了高纬度地区强烈极光的亮度。
