Milky way
Milky way is the Galaxy which we lives ( the name means that the Galaxy with the appearance of Earth). The milky way galaxy is a barred spiral Galaxy with four major in it's disk and a newly discovered outer arm. super massive black hole in it's center (call's as Sagittarius A*).
Milky way galaxy profile:
The milky way galaxy have been forming about 13.5 billion years ago and eating other small galaxies in it's way and the milky way has been for med in the denser area of the early universe.

The milky way is a small part of the local cluster of galaxy which is the part of the virgo super cluster.
The first of the star's that forms in the milky way galaxy is still on the globular cluster.
The milky way galaxies neighboring galaxy is Andromeda galaxy and the scientist predict that the milky way galaxy will collide to the Andromeda galaxy in 4 billion years also they says when it collide and makes a big elliptical galaxy.
