Humans were always fascinated by nature, fire, water, stars... They tried to understand or imagine the rules of this universe. We came a long way from the prehistoric time... We have so much technology and we understand so many of the mysteries of the universe. Or do we? We understand the motion of the planets and stars, we have theories about the size of our galaxy but we're still limited to our beautiful Earth and warm, yellow Sun... We dream of getting someday on another planet or inside of a different solar system.
Stars were considered almost magical, objects that can influence our future and fate. We saw dragons, lion, heroes and gods... Roman gods still give the name of the brightest objects in the night sky: planets.
