How does the milky way | Earth, Solar System and Universe.
If we could see the milky way from outside of it, we would see Centre
bulky, yellow and bright, with rugby ball shape, and a thin disc of
bluish turning around.
The milky way is spiral shaped barrada, as a grinder. In the Center there is a black hole, which scientists call Sagittarius A. The Center is not round, but somewhat elongated. Near it are old, red, and yellow stars.
The Center give birth to four arms: Perseus arm, arm of Orion, Sagittarius arm and arm cross Centaur. They form a disc that rotates slowly spiral. On the arms are younger stars, white and blue. There are also many nebulae; in most of these new stars are formed. The Sagittarius arm is the brightest of all.
The milky way is a large galaxy. Measure diameter light 100,000 years and contains more than 200 billion stars. Their gravity is so powerful, that attracts other smaller nearby galaxies.
Earth is 25,000 light-years from the center of the Galaxy, in an area that is sparsely populated in the Orion arm. Our Solar system takes 225 million years on a full ride to the milky way.
Also called the Milky the Camino de Santiago, as formerly it served as a guide to the pilgrims going to Santiago de Compostela. Compostela means field or road star.
