aurora
plural
aurorasA brilliant display of bands or folds of variously colored light in the sky at night, especially in polar regions. Charged particles from the solar wind are channeled through the Earth's magnetic field into the polar regions. There the particles collide with atoms and molecules in the upper atmosphere, ionizing them and making them glow. Auroras are of greatest intensity and extent during periods of increased sunspot activity, when they often interfere with telecommunications on Earth.
◆ An aurora that occurs in southern latitudes is called an aurora australis (ô-strā|||PRIMARY_STRESS|||lĭs) or southern lights. When it occurs in northern latitudes it is called an aurora borealis (bôr′ē-ăl|||PRIMARY_STRESS|||ĭs) or northern lights.

When To Use
An aurora is a natural light display in the sky that is caused by particles from the sun interacting with a planet’s magnetic field.The most well-known aurora is the aurora borealis, the shimmering display of colorful lights that sometimes appears in Earth’s Northern Hemisphere. The phenomenon is also commonly called the northern lights. The aurora that occurs in the Southern Hemisphere is called aurora australis or the southern lights. (The word borealis is Latin for boreal, which simply means “northern.” The word australis is Latin for austral, which simply means “southern.”)On Earth, auroras appear in many colors ranging from green and pink to red, yellow, and blue. Both the northern and southern versions can be called aurora polaris because they occur around Earth’s poles, but this term is not commonly used.Auroras are not exclusive to Earth and occur on every planet in our solar system except Mercury.
