Etymology: "Aurorae" is the plural of "aurora," the Latin name for the dawn goddess, and the Roman poet Ovid used the figure of Aurora as a personification of the morning light. In Latin, "aurora" was tied to the word for dawn, and it passed into English as a poetic name for the sunrise before it was ever applied to lights in the night sky. The sky phenomenon took its name from that same goddess. Because the northern lights often appear in the hours before dawn and glow in the colors of morning, people compared them to Aurora's rising. The Latin plural "aurorae" keeps the form of the original noun, so it appears in more formal or scientific writing, while "auroras" is also accepted in modern English.

Synonyms: northern lights, polar lights
