POLAR LIGHTS Meaning and
Definition
-
Polar lights, also known as auroras, are naturally occurring atmospheric phenomena characterized by bright and colorful lights that illuminate the northern and southern polar regions of the Earth. These luminous displays are caused by the interaction between the solar wind and the Earth's magnetic field.
When charged particles from the Sun, predominantly electrons and protons, are ejected into space, they travel towards the Earth at high speeds. As they approach our planet, they are deflected by the magnetic field, forming two oval-shaped regions around the magnetic poles called auroral ovals. Auroras can be seen within these ovals, typically between 60 and 75 degrees latitude.
The polar lights take on various colors depending on the type of gas in the atmosphere and the altitude at which the interaction occurs. The most common colors observed are green, caused by oxygen molecules at approximately 100 kilometers above the Earth's surface, and red or purple, resulting from high-altitude oxygen emissions. Blue and pink hues can also be observed, which are more rare and caused by nitrogen and molecular nitrogen, respectively.
Polar lights often appear as ribbons or curtains of light, and their intensity can vary from faint glows to vibrant and fast-moving displays. The phenomenon is most commonly seen during the winter months when the nights are dark and the polar regions are in darkness for an extended period. It is a captivating spectacle that has fascinated humans for centuries and continues to inspire awe and wonder.

Etymology of POLAR LIGHTS
The word "polar lights" refers to the natural phenomenon of bright lights in the night sky observed in polar regions, commonly known as the Northern Lights (aurora borealis) in the Northern Hemisphere and the Southern Lights (aurora australis) in the Southern Hemisphere.
The term "polar" comes from the Latin word "polaris", meaning "of or pertaining to the poles". It is derived from the Latin word "polus", which means "end of an axis" or "point around which something revolves". This is in reference to the Earth's geographical poles, namely the North Pole and the South Pole.
The word "lights" refers to the illumination and radiance exhibited by this phenomenon in the sky.
Therefore, the term "polar lights" represents the lights observed in the polar regions, which are caused by the interaction of charged particles from the sun with the Earth's magnetic field.
