The Universe and our Solar System

CIENCIAS SOCIALES PRIMARIA

INTRODUCTION

 When we see a cloudless night sky, we can see thousands of dots that shine, with more intensity than others. All these dots are stars or celestial bodies.

Fifteen billion years ago, there was a huge explosion, known as "The Big Bang", which was the origin of the universe.

The universe is made up of millions of galaxies. Our galaxy is called the Milky Way, and in it is located the solar system, and therefore our planet Earth.

Nowadays, everything we know about the universe, is the result of years and years of research.
