fathom-the-universe: The word galaxy is derived from the Greek galaxias, meaning “milky” and the name was originally reserved for the light band of stars seen in the night sky which is our own Milky Way Galaxy seen side on. We now know our sun is one of billions of stars in this giant spiral star system, and that this system is one of many. There are many billions of galaxies in the observable universe alone, containing anywhere from millions to trillions of stars each.
