Milky Way Galaxy
There is nothing more mysterious and fascinating look at the sky apart from the galaxy,which stretches like a strand of jewels from one end of heaven to the other end of the sky.In the olden times, when people look at this great show, they were filled with awe of its beauty just like us. But because it does not really know what it is, they make all sorts ofweird and wonderful explanation of the galaxy.

Our galaxy is roughly shaped like a watch, round and flat. If we can rise above it andlooking down, the galaxy looks like a great watch. But we are now in this galaxy, and if we look to the means we look toward the edge of the "watch" it. Thus, we see that the edgethat surrounds us. And because there are millions of stars in it, we see that as the Milky Way galaxy.
Note that there are at least three billion stars in the galaxy. And here's an idea of its size.It takes eight minutes for light from the sun to reach earth. The galaxy rotates on its headlike a wheel. From our position in the galaxy, would require approximately 200 millionyears only to make one revolution. Galactic year is defined as the time it takes the sun to circle the galaxy is about 240 x 10 ^ 6 years. The calculation of the mass of the galaxy, can also be done by Kepler's formula.
