aurora borealis
This term refers specifically to the Northern Lights. While the word aurora can be used generally for any polar light display, the addition of borealis (from the Latin for north wind) restricts the meaning to the Arctic region. Its counterpart in the Southern Hemisphere is the aurora australis.
In a scientific context, the term is used to describe the interaction between solar wind and Earth's magnetic field. In a descriptive or poetic context, it is often associated with terms like shimmering, ethereal, or curtains of light to capture its fluid, shifting appearance.
Meanings
