This page describes a video Icelandic Rivers of Light, by Sergio Díaz Ruiz, Spain
Video caption:
Second place in the 2021 IAU OAE Astrophotography Contest, category Aurorae (time-lapses)
This video shows how aurorae evolve slowly over timescales of a few minutes. Note the clouds being illuminated from behind in the last two shots. Aurorae are caused by interactions between the charged particles blown out in huge explosions from the Sun and the Earth's magnetic field. The changes over time are caused by huge waves of particles pushing the Earth's magnetic field into strange shapes before it snaps back into place.

Video caption: ২০২১ আইএইউ ওএই অ্যাস্ট্রোফটোগ্রাফি প্রতিযোগিতায় দ্বিতীয় স্থান, ক্যাটাগরি অরোরা (টাইম-ল্যাপস)
এই ভিডিওটি দেখায় কিভাবে অরোরা কয়েক মিনিটের টাইমস্কেলে ধীরে ধীরে বিবর্তিত হয়। শেষ দুটি শটে মেঘগুলি পিছন থেকে আলোকিত হচ্ছে লক্ষ্য করুন। সূর্য এবং পৃথিবীর চৌম্বক ক্ষেত্র থেকে বিশাল বিস্ফোরণে উড়িয়ে দেওয়া চার্জযুক্ত কণাগুলির মধ্যে মিথস্ক্রিয়া দ্বারা অরোরা সৃষ্ট হয়। সময়ের সাথে সাথে পরিবর্তনগুলি কণার বিশাল তরঙ্গ দ্বারা সৃষ্ট হয় যা পৃথিবীর চৌম্বক ক্ষেত্রটিকে অদ্ভুত আকারে ঠেলে দেয় এবং এটি পুনরায় জায়গায় ফিরে আসার আগে।

Video caption: Secondo posto al Concorso di Astrofotografia IAU OAE 2021, categoria Aurore (time-lapses)
Questo video mostra come le aurore si evolvono lentamente nell'arco di pochi minuti. Si noti che le nuvole sono illuminate da dietro nelle ultime due immagini. Le aurore sono causate dalle interazioni tra le particelle cariche emesse dalle grandi esplosioni del Sole e il campo magnetico terrestre. I cambiamenti nel tempo sono causati da enormi ondate di particelle che mutano la struttura del campo magnetico terrestre in forme strane prima di farlo tornare alla struttura iniziale.

这段视频展示了极光如何在几分钟的时间尺度上缓慢演变。注意最后两个镜头中从后面照亮的云层。极光是由太阳爆发中喷出的带电粒子与地球磁场相互作用引起的。随时间变化的原因是巨大的粒子波推动地球磁场形成奇怪的形状，然后磁场会恢复原状。
