The universe refers to all that exists, whether visible (solid), or not visible (air). Objects in the universe can be divided into two main groups, the living and nonliving matter.
Some scientists believe that the Universe started with a big explosion that formed space, time, energy, and matter. In the Universe are galaxy clusters has been too big to be known as a general group, consisting of clusters of smaller galaxies. In clusters of galaxies are smaller than the general group, in which we are known as the Local Group. There are 30 galaxies including the Milky Way that have been identified, revolves around the center of the local group. In each galaxy is estimated there are100,000 million stars and galaxies typically every form of flat and slightly thicker in the middle you like dishes with a diameter size of 100,000 years cahaya. Although, there are spiral galaxies, crossed circle, ellipse, non-uniform shape. Each galaxy rotates around the center of the galaxy, and this includes the solar system located at the edge of two-thirds of the Milky Way galaxy, about 30 thousand light years away from the center. Solar System takes 220 million years to complete one circulation around the center of the Milky Way galaxy. In the solar system are all nine planets revolving around the sun. Some planets in our solar system has a moon orbiting around them.
