Answer:
In Norse mythology, the northern lights, also known as the aurora borealis, were believed to be caused by the goddess Freyja and her daughters, the Valkyries. According to the mythology, Freyja and the Valkyries rode through the sky on their horses, pulling a chariot that was filled with torches. As they rode, the sparks from the torches would fly off and create the northern lights in the sky. In some versions of the mythology, the northern lights were also said to be caused by the fire-breathing dragon that guarded the gates of Valhalla, the Norse heaven. The northern lights were considered to be a sign of the gods' presence and were thought to be a good omen.
