You guys know about the Galaxy? Maybe we often wear the term "Galaxy" in everyday conversation, but it seems like there's not much that really understand its meaning.

As far as can be examined and measured in detail by humans, there are no fewer than one hundred billion galaxies in the universe! Well come back, what is a Galaxy.

A simple understanding of the Galaxy is, a bunch of space material which consists of stars, gas, dust, and other heavenly bodies are bound by a system of equal gravity.

Our solar system, with the Sun as its Center, is part of a galaxy called the milky way.

Milky way, our home

As with many other galaxies, the Milky Way's spiral-shaped, with two main arm (major arms), two arms and a minor (minor arms).

Then where the layout of our solar system.

The Sun and planets Entourage in one of the minor arm called the Orion. Arm (or belt) Orion is located between two major arms arm Perseusdan arm of Sagittarius.

The milky way is made up of billions of stars, many of whom, larger and older than our Sun. The diameter of the milky way is 100,000 light years across and is comprised of a thousand light years away.

In the center of the Galaxy is believed there was a very massive black holes, people might call "supermassive black hole.

Do galaxies move? The answer is Yes. All galaxies move, good motion rotating (spinning), or the motion of walking across the universe. In this trip is estimated at milky way's closest Galactic neighbors might hit named Andromeda.

By calculating the distance and the speed rate of the great collision of galaxies, it is expected to happen four billion years to come

But at that time it was estimated the Sun also has evolved and enlarged into a giant red star (red giant). This of course makes the Earth is no longer a planet that could be livable
