 Appearance  Size and composition  Video Shows galaxy  Structure and Formation  Age 2
 The Milky Way has a relatively low surface brightness. Its visibility can be greatly reduced by background light such as light pollution or stray light from the moon.  The light in this band originates from un-resolved stars and other material that lie within the Galactic plane 3
 The Milky Way contains at least 100 billion stars and may have up to 400 billion stars.  The stellar disk of the Milky Way Galaxy is approximately 100,000 ly (31 kpc) in diameter. 4
This Video shows a panoramic view for galaxy 5
 It consists of a bar- shaped core region surrounded by a disk of gas, dust and stars.  The gas, dust and stars are organized in roughly logarithmic spiral arm structures. 6
 a star in the galactic halo was estimated to be about 13.2 billion years old.  About 0.5 billion years less than the age of the universe. As the oldest known object in the Milky Way at that time 7
 This galaxy conations millions of stars  The milky way galaxy is the most galaxy studied by space scientific specialist because it contain our plant. 8
