GALACTIC POLES Meaning and
Definition
-
Galactic poles refer to the two opposite points in the celestial sphere where the axis of a galaxy intersects the celestial sphere, usually referencing the Milky Way galaxy. The galactic poles are determined by the galactic coordinate system, a celestial coordinate system used to describe the position of objects within our galaxy.
In the case of the Milky Way, the axis of rotation runs roughly perpendicular to the plane of the galaxy. This means that the celestial sphere intersects the galaxy's plane at two points, called the galactic poles. The North Galactic Pole (NGP) and the South Galactic Pole (SGP) are the two corresponding points where the axis of the Milky Way extends into space.
These poles are useful reference points for astronomers, as they can be used to locate other celestial objects within the Milky Way galaxy. Furthermore, studying the distribution of celestial bodies relative to the galactic poles can provide insights into the structure, motion, and dynamics of our galaxy. These reference points also aid in determining the orientation of the Milky Way relative to other galaxies or structures in the universe.

Etymology of GALACTIC POLES
The word "galactic" refers to anything related to a galaxy, specifically the Milky Way galaxy in this context. The term "pole" originates from the Old English word "pāl" meaning a stake or post. It was adopted in Middle English and eventually came to represent the geographical poles of the Earth.
Therefore, the term "galactic poles" combines "galactic" and "poles" to describe the two points of reference in the Milky Way galaxy that are similar to the Earth's geographical poles. These points are located at the extreme ends of the galactic axis, and they play a significant role in studying the orientation and structure of our galaxy.
