Where We Live?


IF WE GO DEEP INTO OUR SPACE
WE WILL FIND THAT WE LIVE IN A GALAXY
IT IS CALLED "THE MILKY WAY"
WHT YOU KNOW ABOUT IT?


The Milky Way (a translation of the latin Via Lactea, in turn derived from the Greek Γαλαξίας (Galaxies) sometimes referred to simply as "the galaxy"), is a barrade sperial galaxy that is part of the local group of galaxies. Although the Milky Way is one of billion of galaxies in the observal univarse, the Galaxy has special significance to humanity as it is the home galaxy of the planet earth. The Milky Way galaxy is visible from Earth as a band of light in the night sky, and it is the appearance of this band of light which has inspired the name for our galaxy


Some sources hold that, strictly speaking, the term Milky Way should refer exclusively to the observation of the band of light, while the full name Milky Way Galaxy, or alternatively the Galaxy should be used to describe our galaxy as an astrophysical whole. It is unclear how widespread the usage of this convention is, however, and the term "Milky Way" is routinely used in either context.
